LCD Digital Thermometer Hygrometer with External Sensor

The LCD Digital Thermometer Hygrometer with External Sensor is a versatile device designed to accurately monitor indoor and outdoor temperature and humidity levels. Featuring a clear display, it can easily switch between degrees Celsius and Fahrenheit, catering to your preference.

This unit includes a highest/lowest temperature and humidity function, allowing you to track the extremes of your environmental conditions. Additionally, the frost point alarm function alerts you when temperatures are between -1C and +4C (30.2F to 39.2F), ensuring you stay informed of potential cold weather impacts.

The comfort display visually indicates when your indoor environment is within the optimal range. Comfort is defined as an indoor temperature between 20C and 25C (68F to 77F) with humidity levels ranging from 40% RH to 70% RH. If humidity exceeds 70% RH or drops below 40% RH, warnings will be issued accordingly. Furthermore, if the temperature falls below 20C or rises above 25C while humidity remains between 40% RH and 70% RH, the comfort display will not show any indicators.

With compact dimensions of 70 x 81 x 20 mm, this thermometer and hygrometer is easy to place in any setting. It requires one 1.5V AA battery (not included) for operation. In the packaging, you will find the digital LCD thermometer hygrometer and a user manual in English.

For operation, simply open the battery cover, insert the battery with the positive side facing up, and secure the cover back in place. The device features several buttons: the [MAX/MIN] button displays the maximum and minimum recorded values for indoor and outdoor conditions, while the [C/F] button lets you switch between temperature units. The [CLEAR] button resets the maximum and minimum records, and the [FREEZE ALT] button allows you to activate or deactivate the frost point alarm. To set the frost point alarm, press the [FREEZE ALT] button for two seconds.
