A reliable choice trusted by growers for years, the ETI Min/Max Thermo-Hygrometer offers accurate monitoring of both temperature and humidity.

It features built-in sensors to measure the temperature and humidity at the unit's location, as well as an external probe that provides an additional temperature reading. This allows you to monitor conditions both in the grow space (such as a room or tent) and directly among the plants.

The internal sensors measure temperature from -19.9°C to 69.9°C and relative humidity from 20% to 99%. With the external temperature probe, the temperature range extends from -49.9°C to 69.9°C.

Key Features:

• Dual temperature monitoring (internal and external)
• Measures relative humidity
• Records minimum and maximum readings
• Proven reliability among growers
