Sentinel has combined digital temperature and humidity controls together in one flexible unit called the EVC-2. It is EXTREMELY accurate and can control temperature and humidity levels independently OR combine the functions to activate together. Unlike other competing controllers, the EVC-2 has been designed to be easy to understand. Each function has a clearly identified “pushbutton” and a large LCD display. No complicated menus to negotiate. It also records minimum and maximum temperature and humidity levels. The EVC-2 also has a16 ft remote probe assembly so the temperature and humidity can be measured exactly where you would want to… at plant level.
