The newly developed ear/forehead thermometer calibration device DCHW by Shanghai Hengping-0515A， It is a calibration instrument specifically designed for non-contact infrared human body thermometers such as infrared ear thermometers and infrared forehead thermometers.

1. Adopting microcomputer temperature control PID regulation and self-tuning control technology, the temperature control accuracy reaches ± 0.01 ℃

2. Adopting a large frequency screen LCD display for a more intuitive understanding of the working status

3. Fully enclosed environmentally friendly brand compressor refrigeration system, CFC free, fast cooling.

4. The body shell adopts anti-aging electrostatic spraying technology, and the platform, inner tank, mixing pump, etc. are all made of high-quality SUS304 stainless steel material, with excellent workmanship;

5. Exquisite workmanship of the front panel and countertop of the chassis, combined with unique humanizationRThe rounded design structure can prevent operators from being accidentally injured by sharp edges.

6. Detachable ventilation grille for easy cleaning of the condenser of the refrigeration unit

7. Internal circulation function: Adopting a non heat centrifugal circulation pump to avoid the influence of traditional water pumps on the tank temperature field due to their own heat generation.

8. Safety protection device for low-temperature constant temperature bath:

1) Equipped with power-off protection function

2) Capable of setting upper and lower temperature limits

3) Temperature runaway protection and alarm function

4) The heating device has low water level anti dry burning and explosion-proof functions

5) Multiple protection functions for compressor overheating and overcurrent

6) There is a sensor open circuit display function

9. Optional high emissivity blackbody with an emissivity of 0.99.
