The HTDF humidity logger is a data logger that measures and records both relative humidity (% RH) and temperature over the range of -20 to 85 °C and 0 to 100% RH. At programmable intervals, the HTDF 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 HTDF 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 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 USB cradle.
