Measure and display both temperature and humidity at the same time with the ETI 810-155 therma-hygrometer!

Both temperature and humidity can be measured using built-in sensors with range from 20 to 99% RH for humidity and 0 to 49.9°C. An external temperature sensor probe is also included which can be used to measure temperature from a specific area from -49.9 to 69.9°C.

When temperatures reach 0°C or below (as detected by the remote probe), the 810-155 will sound an audible alarm. This is ideal for use in frost/freeze alerting in horticulture and similar applications.

Additional functions of the 810-155 includes a MAX/MIN mode which will calculate maximum and minimum temperatures over a period of time and the ability to switch between Celsius and Fahrenheit measurement modes with a simple button press.
