HTBF humidity temperature recorder blind with external sensors

- Stores up to 16,000 readings. - LED shows if limits are exceeded. - Dual function data logger. - User Manual - Certificate of conformity Note: When ordering loggers, it is necessary to order at least one ThermaData® logger holder. The ThermaData® HTBF Humidity Logger is a portable blind logger that measures and records both relative humidity (%RH) and temperature over a range of -20 to 85°C and 0 to 100% RH. At programmable intervals, the HTB humidity logger records temperature and humidity simultaneously, logging up to a maximum of 16,000 readings (8,000 humidity and 8,000 temperature). The ThermaData® HTBF Blind Humidity Logger includes internal humidity and temperature sensors. Each humidity logger includes a red and green LED, flashing green LED indicates the logger is active/logging and flashing red LED indicates your custom preset alarms have been exceeded. ThermaData humidity and temperature loggers are suitable for a wide range of applications including HVAC climate monitoring, quality control or storage areas and many more. Note: When ordering loggers, it is necessary to order at least one ThermaData® logger holder, which includes the software. A UKAS 3-point humidity calibration certificate (25, 50 and 75% RH) is available as an option at a preferential price when purchased with these thermo-hygrometers. ThermaData Studio software is compatible with all models of ThermaData loggers, including wireless. The software is both powerful and user-friendly, organizing and analyzing temperature data to provide management information.
