This type of hygrometer thermometer is useful for measuring the temperature and humidity at home.Temperature and humidity sensors are integrated in the device.
The display is large enough and the digits are well recognizable.What is missing is pointing decimal values,the device only shows the full value. This thermometer – hydrometer is beter for accuracy but has a smaller display.
If you need humidity switch good choice is KT3012
Test Thermometer + Hygrometer with integrated sensors
I tested the accuracy of this device in my lab. I compared it with Testoterm calibrated device for measuring temperature and humidity. The results are good. Thermometer + Hygrometer has good accurate, but a little longer stabilizes.
After 20 minutes of stabilization + thermometer hydrometer showed the following values
Temperature… 24 ° C
Humidity is .. 27%
For control the Testoterm showed 24.6° C temperature and 25.9% humidity. Result is good!
