The RHT20 is a humidity and temperature datalogger that can record up to 16,000 values with a user-programmable sample rate. USB interface for simple configuration and data download. Data sampling rates can be set anywhere from 1 second to 24 hours. Alarm thresholds for humidity and temperature can be programmed by the user. The LCD displays the current temperature and humidity values, as well as the Min/Max and Alarm status. Long battery life. Install or attach the datalogger in a monitoring position (storage bin, vehicle, cargo hold, freezer, temperature-controlled chamber, etc.). The datalogger records temperature and humidity at the user-specified sampling rate. To retrieve readings, connect the datalogger to your PC via the USB interface. The datalogger displays the current humidity and temperature, as well as the min/max and alarm status, which may be accessed at any point during the recording process. Complete with
