The PCE-THB 38 air humidity meter is ideal for detecting and digitally displaying humidity, temperature and barrometric pressure. Temperature is measured by an RTD sensor and air humidity is measured by a highly repeatable capacitive sensor. The air humidity meter also calculates dew point. The air humidity meter also shows atmospheric pressure in a range of 10 to 1100hPa. With all of these features, it is a complete climatological device. It is shipped from the manufacturer already calibrated. Otherwise, a laboratory calibration and certificate can be ordered which meets ISO calibration standards.
