The RV2100 electronic digital display temperature and humidity meter is a simple handheld electronic digital display temperature and humidity meter imported from TQC of the Netherlands. It can display temperature and air humidity values ââââat the same time. RV2100 digital display temperature and humidity meter has the function of storing MIN/MAX values, ℃/â selection function, holding function and dew point indication function.
The 3 AAA batteries used in the RV2100 digital thermometer and hygrometer can support the thermometer and hygrometer to continuously measure up to 10,000 hours. It will automatically shut down after 10 minutes of no operation.
! Humidity sensor note:The built-in humidity sensor of the RV2100 electronic digital thermohygrometer is easily contaminated by contaminants, such as solvents, exposure to saturated air, etc., and is therefore not covered by the 1-year warranty. Additionally, sensor readings can drift by up to 0.5% per year.
Suitable for steel industry, wood, wholesale, transportation, shipping industry, food, laboratory, aviation, air conditioning, coating industry, automobile, paint, etc.
