Temperature & Humidity Meter Indoor and Outdoor Temperature Hygrometer round Temperature & Humidity Meter Multicolor

temperature and humidity table widely used in home, laboratory, breeding industry, instrument workshop, library, hospital, computer microcomputer room, etc.
especially with the continuous improvement of people's living standards, it is more important to measure environmental temperature and humidity when air conditioning and heating enter families, hotels and restaurants.

measurement range:

   temperature-30 ℃-50 ℃
humidity 20% rh-100% rh
technical indicators:

   temperature below 10 ℃ ± 1.5 ℃ 10 ℃-25 ℃ ± 1 ℃ above 25 ℃ ± 1.5 ℃
humidity below 40% ± 7%rh 40%-75%±5% rh above 75%± 7%rh

best environmental temperature and humidity reference value:

★the most suitable environment for human body: temperature 15 ℃-25 ℃, relative humidity 40% rh-75%rh

★living environment: 40% rh-70%rh

★library, art gallery, museum: 40% rh-60%rh
