The device’s fully digital operation and a large 2.1 inch, high-contrast red OLED display make setup and control intuitive and fast. Instantly view real-time power consumption (in Amperes) and input voltage at a glance.

An included external temperature and humidity sensor provides continuous monitoring of relative humidity, ambient temperature, and dew point—essential for maintaining optimal conditions.
