Product Description

Product Overview of Thermometer Calibration Device

NM-TWJ Thermometer Calibration System is mainly used for calibration of non-contact infrared body temperature measuring instruments, such as infrared ear thermometer and infrared forehead thermometer, as well as verification of glass thermometer and medical electronic thermometer. This product is a high-precision auto-control digital temperature calibration device, with the characteristics of good temperature stability, uniform temperature field, high temperature control accuracy, low noise, good reliability and long service life. The device adopts PID for temperature regulation to realize automatic temperature control. It is of compact structure, easy to operate and shows indicating value intuitively. This product is suitable for the calibration and use of non-contact infrared body thermometer by manufacturers, measuring units, medical and health departments, etc. The performance index of the high-precision thermostatic source matched with this product conforms to the verification regulation for glass thermometers and medical electronic thermometers.

Features of Thermometer Calibration Device

1. The thermostatic bath for calibration of NM-RTS05TB thermometer is a thermostatic source specially designed for calibrating the thermometer. Its volume is only 1/2 of an ordinary thermostatic bath. Thus, it is easy to carry and move. Totally-enclosed environment-friendly compressor refrigeration system, without CFC.

2. The latest generation of integrated PID automatic temperature control program and the high-precision Pt100 temperature sensor are built in. A touch screen operation panel is provided, and it is easy to operate with high digital display resolution to ensure accurate and stable temperature control.

3. The high uniformity of flow field and temperature field in the bath is realized by using the side stirring circulation system.

4. The exterior of the black body cavity is plated, and the interior is covered with a black body coating of high emissivity to ensure high black body emissivity and long service life.

5. The anti-aging electrostatic spraying technology is applied to the body shell, and the high-quality S304 stainless steel is used for the inner bath.

6. The shell with fine workmanship and unique humanized design structure are convenient for operators to use.
