More info

The MTP ST-171 digital thermo hygrometer with buil-in USB port, comes with a very precise temperature and relative humidity sensors. This temperature humidity gauge provides continuous monitoring of the temperature and dew point temperature (from -40 to 70°C ) and relative humidity (0 to 100% RH). Thanks to its small size the MTP ST-171 can be used into tiny spaces. During the environmental measurements you can save up to 32000 readings into its internal memory and save those measurements on your local PC using the USB port and the analysis software (included).

Simply plug the MTP ST-171 Datallogger into the USB port of your computer to begin downloading - no cables or wires are required

When both temperature and relative humidity readings exceed alarm level synchronously, LED status indication alternate every cycle. For example: If there is only one alarm, the REC LED blinks for one cycle and alarm LED will blink for next cycle. If there are two alarms, REC LED will not blink. First alarm will blink for first cycle and the next alarm will blink for next cycle. To save power, alarm LEDs for temperature and humidity can be disabled via the supplied software.
