ThermaData® HTB Blind Humidity Logger — Internal Sensors

The HTB Humidity Data Logger is a portable blind humidity logger that measures and records both relative humidity (% RH) and temperature over the range of -20 to 85°C and 0 to 100 %rh.

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. Please note: when ordering loggers it is necessary to order at least one ThermaData logger cradle. 

At programmable intervals, the HTB 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 data logger includes internal humidity and temperature sensors.

Each HTB ThermaData 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.

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.

ATTENTION HUMIDITY SENSOR The Humidity Sensors housed in these products are susceptible to contamination from pollutants such as solvents and exposure to saturated air and therefore are not covered under the 2 year warranty. Furthermore it is expected that the sensor’s readings will drift by up to 0.5% per year.
