MicroLite USB Temperature and Humidity Logger




This MicroLite logger measures temperature, relative humidity and dew point over a range of -40 to 80 ˚C and 5 to 95 %. With a 32,000 sample cyclic memory, the MicroLite Temp/RH logger features a USB interface for easy connection to a PC for user configuration, data download and sensor calibration using the free Windows-based DataSuite data analysis software.

You can setup low and high alarm thresholds and view the logger data (including dew point) on the 4-digit LCD, which scrolls between the current and minimum/maximum readings. The LED provides additional sample and alarm indication in the event the LCD is off due to the MicroLite's power save mode.

The logger is designed for both portable and stationary multi-use operation with a replaceable 3V coin battery lasting up to 1.5 years, depending on the operating conditions.


Together with the DataSuite software the MicroLite Temp/RH is also 21 CFR Part 11 compliant.
