II. Special Blackbody Thermostatic Bath for Clinical Thermometers

The special blackbody thermostatic bath for clinical thermometers is equipped with a blackbody cavity for forehead thermometers and a blackbody cavity for ear thermometers. It is mainly used for calibrating infrared ear thermometers (guns) and infrared forehead thermometers (guns), and can also be used for calibrating infrared body surface screening instruments. It complies with JJG 1164-2019 Verification Regulation for Infrared Ear Thermometers and other relevant verification regulations.

Main Technical Parameters

  • Temperature range:(0 ~ 95) °C

  • Accuracy:±0.1 °C

  • Stability (Fluctuation):±0.02 °C / 10 min

  • Uniformity:±0.02 °C

  • Resolution:0.001 °C

  • Emissivity:≥ 0.999

  • Forehead thermometer blackbody cavity test aperture:Φ45 mm

  • Ear thermometer blackbody cavity test aperture:Φ10 mm

  • Overall dimensions:680 × 645 × 1400 mm

  • Equipped with a 7-inch touchscreen display for simple operation

  • Isothermal blackbody cavity with a single cavity opening — cavity opening radiation is uniformly distributed across the spectrum, with cavity opening emissivity above 0.999

  • Heating element is insulated from the outer shell; special software-limited heating is used, eliminating the need for high-power power transformers

  • Temperature fluctuation curve — built-in temperature control curve in the system for real-time monitoring of temperature changes
