Description of Thomas Traceable Hygrometer Thermometer Barometer

Digital thermometer, hygrometer, and barometer for measuring temperature, humidity, and barometric pressure. Measures temperature from 0 to 50 degrees C (30 to 122 degrees F), with an accuracy of + or - 1 degree C. Measures humidity from 10 to 95% RH, with an accuracy of + or - 3%. Barometer measures pressure in inches of Mercury (inHg), millibars (hPa), and millimeters of Mercury (mmHg). Calibrated to ISO 17025 traceability standards for reliability of measurements.

Inaccurate Readings and Glitchy Display

My analysis of this hygrometer thermometer barometer showed that the readings were consistently off by a significant margin, making it impossible to rely on for accurate measurements. Additionally, the display would sometimes glitch out AND require resetting..

Pros
  • None
Cons
  • Inaccurate readings, glitchy display.

Excellent accuracy for the price

It is quite unusual for a hygrometer under $200 to come with an individually numbered certificate of calibration. This one does. However, since it only comes with a one-point calibration (23°C, 46% RH), I tested mine at various temperatures and relative humidity levels. Checking the temperature was easy for me: first I calibrated the digital thermometer in ice water and in boiling water, then I compared this device with this thermometer (I could not directly check this device in water because…

Pros
  • Ideal for outdoor activities
Cons
  • Not sure
