Compact USB Temperature and Relative Humidity Data Logger

The OM-62 temperature/relative humidity data logger is an easy-to-use, versatile device which can be used for a wide range of logging applications. The OM-62 is capable of sampling as fast as once per second or as slow as every 18 hours. A total of 43,344 temperature measurements can be stored in the data logger memory if only temperature is measured, or 21,672 measurements for temperature and humidity.

In addition to measuring temperature and relative humidly, the easy-to-use Windows software included with the OM-62 data logger calculates and displays the dew point temperature. The software is a full-featured program that allows you to set up all data logger functions including sampling rate, logging duration, start mode, logging mode, and high and low temperature and relative humidity alarm values.
Once data has been logged, the program then allows you to download data from the logger, plot the data and export the data to an ASCII text or Excel file format for further analysis.
