Product Overview

The Electronic Cadaver Thermometer — High-Precision Semiconductor Sensing, ±0.1℃ Accurate Measurement, -20℃ to +50℃ Wide Range, Forensic Autopsy Rectal Temperature Acquisition & Postmortem Interval Estimation Auxiliary Detection System (also referred to as the FGCW-Ⅰ Electronic Cadaver Thermometer or Cadaver Rectal Thermometer) is a dedicated electronic temperature measurement instrument based on semiconductor sensing technology. It constitutes a foundational and essential quantitative detection device in the fields of forensic pathological autopsy, postmortem interval estimation, and preliminary scene investigation. This product is deeply customized for precisely and rapidly measuring the deep body temperature of a cadaver (usually rectal temperature) and providing critical foundational data for estimating the postmortem interval (PMI) in conjunction with environmental temperature and other parameters. It perfectly adapts to various professional scenarios, including immediate temperature measurement of a cadaver at a homicide scene for preliminary PMI estimation, standardized data acquisition during systematic autopsy in a forensic autopsy room, special temperature measurement of cadavers under refrigerated or extreme environmental conditions, and assisting in determining whether there was pre-mortem hyperthermia, hypothermia, or post-mortem artificial interference. The system's temperature measurement range covers -20℃ to +50℃, with an accuracy of ±0.1℃. It employs a semiconductor temperature sensor to convert the physical quantity of temperature into an electrical signal, displaying the reading directly on a digital LCD screen. It is one of the most commonly used and most objective quantification tools in the series of methods for forensic postmortem interval estimation and is a basic and essential piece of equipment for forensic laboratories and scene investigations.

Technical Principle

This instrument operates based on the thermoelectric effect principle of a semiconductor temperature sensor. Its core detection component is a semiconductor thermistor element housed within a stainless steel probe. The resistance value or the forward voltage drop of the PN junction of this element exhibits a highly linear and regular change with temperature variation. When the operator inserts the probe into the rectum of the cadaver to an appropriate depth (typically 6-8 cm recommended), the sensor rapidly senses the temperature of the rectal tissue, converting the physical quantity of temperature into a corresponding electrical signal. After signal conditioning, linearization correction, and analog-to-digital conversion by the built-in microprocessor, a precise temperature reading is displayed directly on the digital LCD screen. The sensor typically requires several tens of seconds to reach thermal equilibrium with the deep tissue. The reading obtained once the displayed value stabilizes is the initial rectal temperature value of the cadaver. The system's temperature measurement range covers -20℃ to +50℃, comprehensively meeting the full-scene temperature measurement needs from ultra-low temperature frozen cadavers to decomposed cadavers in high-temperature environments. The accuracy reaches ±0.1℃, a high precision that ensures the reliability of subsequent PMI calculation formulas. The instrument's operating ambient temperature range is -20℃ to +60℃, with humidity <85%, ensuring stable operation in various common indoor and outdoor field environments.

Core Functions and Compliance Operational Value

±0.1℃ High-Precision Deep Body Temperature Acquisition, Providing Reliable Input Parameters for Scientific PMI Calculation Using Methods Such as the Henssge Nomogram

The instrument achieves an accuracy of ±0.1℃. The precisely measured rectal temperature is the most basic input parameter for applying rectal temperature decline curves, such as the Henssge Nomogram method, to estimate the postmortem interval. Combined with corrective factors such as ambient temperature, body weight, clothing, and the surrounding medium, the forensic examiner can calculate an approximate range for the time of death. This high-precision quantitative data fundamentally changes the early forensic practice of relying on subjective empirical judgment based on hand-touch temperature sensation, elevating PMI estimation from qualitative experience to quantitative scientific analysis, and providing an objective data foundation for establishing a critical timeline in case investigations.

-20℃ to +50℃ Wide Range Coverage, Meeting Full-Scene Temperature Measurement Needs from Ultra-Low Temperature Frozen Cadavers to Highly Decomposed Remains

The device's temperature measurement range covers -20℃ to +50℃. It is not only suitable for routine rectal temperature measurement of cadavers at indoor and outdoor scenes but also applicable to the special temperature measurement of refrigerated or frozen cadavers and decomposed cadavers exposed to extreme high-temperature environments, adapting to the full range of climatic conditions across China, from the severe cold of northern winters to the extreme heat of southern summers. When combined with environmental temperature and other parameters, the measurement data can assist in determining whether there were abnormal conditions such as pre-mortem hyperthermia or hypothermia, or post-mortem artificial interference like heating or cooling.

Standardized Operating Procedure and Immediate Data Recording, Ensuring the Objectivity of Temperature Measurement Data and the Completeness of the Forensic Case File

The instrument's operation follows a standardized procedure—the probe is inserted into the rectum of the cadaver to an appropriate depth (typically 6-8 cm recommended). Once the displayed value stabilizes, the initial rectal temperature reading is taken. The measurement time, ambient temperature, humidity, wind speed, and the supporting body surface are simultaneously and accurately recorded. All measurement data is fully and accurately documented and archived as original data. This provides complete parametric support for subsequent PMI calculation and meets the statutory requirements of the Standards for Forensic Pathological Autopsy regarding the completeness and traceability of autopsy data records.

Compliant Application Scenarios

Immediate Temperature Measurement and Preliminary PMI Estimation Scenario for Cadavers at Homicide Scenes

During the scene investigation of a homicide, the forensic pathologist or investigator immediately uses this device to acquire first-hand, objective deep body temperature data from the cadaver at the earliest opportunity, preventing data distortion caused by body movement or environmental changes. The precisely measured rectal temperature, combined with ambient temperature and other parameters, is used to preliminarily estimate the postmortem interval range through scientific methods such as the Henssge Nomogram, providing a critical timeline basis for the case investigation.

Standardized Data Acquisition Scenario During Systematic Autopsy in a Forensic Autopsy Room

During a systematic forensic pathological autopsy, the forensic examiner uses this device to perform rectal temperature measurement in accordance with standardized operating procedures. The temperature measurement data is archived as a statutory component of the autopsy record. In major cases involving multiple deceased individuals, the unified temperature measurement standard and precise data provide a scientific basis for the horizontal comparison and analysis of the postmortem intervals of each body.

Special Temperature Measurement Scenario for Cadavers Under Refrigerated and Extreme Environmental Conditions

For cadavers that are refrigerated, frozen, or exposed to extreme high-temperature environments, the device's -20℃ to +50℃ wide-range temperature measurement capability can accurately acquire their deep body temperature. When determining whether abnormal conditions such as pre-mortem hyperthermia, hypothermia, or post-mortem artificial interference exist, a comparison between the body temperature and the post-mortem phenomena can provide important auxiliary reference.

Core Technical Parameters

The product model is FGCW-Ⅰ. The temperature measurement range covers -20℃ to +50℃, with a measurement accuracy of ±0.1℃. The sensing method employs a semiconductor temperature sensor, sensing the deep tissue temperature via a probe. The display method is a direct reading on a digital LCD screen. The operating ambient temperature range is -20℃ to +60℃, with humidity <85%. The reference price is RMB 560.

Compliant Field Application Cases

An unnatural death case occurred in a city. The deceased was found in a rented apartment where he lived alone, with no obvious signs of violence at the scene. The forensic pathologist immediately used this Electronic Cadaver Thermometer during the scene investigation. Following the standard operating procedure, the probe was inserted approximately 7 cm into the rectum of the deceased. After several tens of seconds, the reading on the LCD screen stabilized, showing a rectal temperature of 32.5℃. The measurement time and ambient temperature were simultaneously recorded. The forensic pathologist, combining the ambient temperature, the deceased's body weight, and clothing, applied the Henssge Nomogram method to estimate the time of death to be approximately 6 to 8 hours before the body was discovered. Based on this postmortem interval range, investigators retrieved surveillance footage from around the time of the incident and successfully identified the suspect who was the last to enter the rented apartment. During the subsequent interrogation, the time of the crime confessed by the suspect was highly consistent with the PMI estimated by the forensic pathologist. The temperature measurement data and the estimation process were admitted as an integral part of the expert opinion during court cross-examination.
