Rotronic HL-20D HydroLog Stand Alone Data Logger.
There are many environments and applications where temperature and humidity need to be monitored and data recorded to ensure that conditions are within specified tolerances, this is often a requirement of Quality Management Systems. These include museums, galleries, laboratories, test facilities, print rooms, production and storage areas, offices and during product transportation.
The Rotronic compact temperature and humidity HygroLog HL-20D stand-alone logger is the perfect device. Using AirChip3000 technology, it provides high precision measurements with an integrated sensor (0.8 %rh, 0.3 °C at ambient) with a configurable logging interval from 5 seconds to 1 hour. The logger has a long battery life and can record measurements for many months. An LC graphical display with backlight is a useful feature and shows temperature and humidity values clearly.
