The PCE-HT 71N Data Logger detects air temperature and humidity and stores readings to its internal memory. This Data Logger is compact and has enough memory to store up to 32,000 readings, 16,000 for each parameter, and is used above all as a Data Logger, in supermarket refrigeration units, refrigerated transport, warehouses and other temperature controlled environments. These temperature and humidity logging test instruments are manufacturer calibrated. An ISO calibration certificate is an option.
