The new ThermaData HTD humidity and temperature data logger is a portable humidity logger with 10mm LCD display that measures and record both relative humidity (% RH) and temperature over the range of -20 to 85°C and 0 to 100% RH.

At programmable intervals, the HTD humidity logger will record simultaneously both temperature and humidity, recording up to a maximum of 16,000 readings (8,000 humidity and 8,000 temperature). The ThermaData HTB humidity logger has a built-in LCD display that shows both temperature and humidity levels and includes internal humidity and temperature sensors.

Each humidity logger incorporates a red and green LED, the flashing green LED indicates that the logger is active/logging and the flashing red LED indicates that your customised pre-set alarms have been exceeded. The humidity and temperature ThermaData loggers are suitable for a diverse range of applications which include HVAC climate monitoring, QA control or storage areas and many more.

An optional 3-point (25, 50 & 75%rh) UKAS Humidity Calibration Certificate is available at a preferential price when purchased with these therma-hygrometers. Select this option from drop-down.
