The Infrared Ear Thermometer And Forehead Thermometer Calibration
System
PanRan Measurement & Control provides a comprehensive infrared ear
thermometer and infrared forehead thermometer calibration solution.
The infrared ear thermometer and forehead thermometer calibration
system consists of three parts:
Part1. Black-body radiation cavity, high-emissivity black-body
radiation cavity is a key component required for the calibration of
infrared ear thermometers and forehead thermometers. Its structure
and the quality of the internal coating have a significant impact
on the calibration results.
Part2. Temperature source--Liquid constant temperature device, used
to place and immerse the black body radiation cavity, so that each
surface of the radiation cavity has excellent temperature
uniformity and temperature fluctuation.
Part3. Temperature standard, used to measure the temperature of the
medium in the liquid thermostat.
Part1. Black-body radiation cavity
There are two types of black body radiation chambers, which are
used to calibrate infrared ear thermometers and infrared forehead
thermometers. The black body cavity is gold-plated on the outside
and has a high-emissivity coating inside. Requirements to meet the
calibration requirements of most infrared ear thermometers and
infrared forehead thermometers.

| Diameter of the hole | 10mm | 60mm |
| Max immersion depth | 150mm | 300mm |
| Flange diameter | 130mm |
Part2. Temperature source--the liquid constant temperature device
The liquid constant temperature device can choose two types of
products, the PR560B infrared thermometer calibration thermostat or
the PR532-N10 refrigeration thermostat, both of which have
excellent temperature stability and temperature uniformity. Among
them, the volume of the thermostat used for the calibration of the
PR560B infrared thermometer is only 1/2 of that of an ordinary
thermostat, which is convenient to move, transport, or transform it
into a vehicle-mounted calibration device.

Note: If the customer already has a constant temperature device
that can meet the calibration requirements, it can also be used
directly.
Part3. Temperature standard
Option 1: In response to the calibration requirements of infrared
thermometers, PanRan introduced the PR712A standard digital
thermometer, with an annual change of better than 0.01 ° C over the
full range. Compared with the PR710 and PR711 precision digital
thermometers of the same series, it has a better built-in reference
resistance, better temperature coefficient and long-term stability.
At an ambient temperature of 10 to 35 ° C, its typical temperature
coefficient is only 0.5 ppm / ° C.
Option 2: Traditional electrical measurement equipment + standard platinum
resistance. The electrical measurement equipment in this solution
can be configured with PR293 series nanovolt micro-ohm thermometer
or PR291 series micro-ohm thermometer. Both series of products can
meet the requirements of electrical thermometers related to
infrared thermometers.

Application:
The high precision cooling thermostatic bath is suitable for
measuring, biochemical, petroleum, meteorology, energy,
environmental protection, medicine and other departments and
manufacturers of thermometers, temperature controllers, temperature
sensors and other manufacturers to test and calibrate physical
parameters. It can also provide constant temperature source for
other experimental research work. Example 1. Second-class standard
mercury thermometer, Forehead thermometers, Infrared Surface
Thermometers, Ear Thermometers, beckman thermometer, industrial
platinum thermal resistance, standard copper-constantan
thermocouple verification, etc.
