ETI ThermaData® HTDF temperature & %RH logger. External sensors. With display. Indicates when temperature limits are reached. USB-C connection. Free software for reporting

The HTDF humidity logger is a data logger that measures and records both relative humidity (% RH) and temperature in the range of -20 to 85 °C and 0 to 100% RH.

With programmable intervals, the HTDF humidity logger simultaneously records both temperature and humidity, storing up to a maximum of 16,000 readings (8,000 humidity and 8,000 temperature). The ThermaData HTDF humidity logger features a built-in LCD screen that displays both temperature and humidity levels.

An optional 3-point (25, 50, and 75% rh) UKAS humidity calibration certificate is available at a preferential price when purchased with these thermo-hygrometers. Select this option from the dropdown menu.

Each humidity logger features a red and a green LED. The blinking green LED indicates that the logger is active/logging, while the blinking red LED indicates that your custom preset alarms have been exceeded. ThermaData loggers are suitable for a wide range of applications, including HVAC climate monitoring, QA control, or storage areas, and many more.

NOTE ON HUMIDITY SENSORS: The humidity sensors in these products are susceptible to contamination from pollutants such as solvents and exposure to saturated air, and are therefore not covered by the 2-year warranty.

Furthermore, the sensor’s readings are expected to drift by up to 0.5% per year.
