HTC-1 Temperature and Humidity Meter User Manual

Product specifications:

Temperature measurement range: -50℃~70℃

Temperature measurement accuracy: approximately ±1.0℃ (1.8 oF)

Temperature resolution: 0.1℃ (0.2 oF)

Humidity measurement range: 10%RH~90%RH.

Humidity measurement accuracy: ±5% (30%-70%) ±7% (other)

This needs some explanation. That is to say, even in a relatively dry room with almost no humidity, its error will increase. Humidity is not like temperature, which can be accurate to about ±1 degree. Even in the laboratory, it cannot be achieved. This device is sufficient for household humidity measurement and is definitely much more accurate than the one that comes with a humidifier! This is just for household use. It will tell us whether the room needs to be humidified or dehumidified. As the guardian of your healthy living space, it is quite competent!
