The new ThermaData HTD humidity logger / 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.
Please note: At least one MT103 USB cradle is required for use with MT102 loggers
