Mini temperature controller

Mini temperature controller

The Kelvinion mini from MultiFields is a compact low-temperature thermostat。It consists of two independent high-precision temperature measurement channels and a high-power PID output channel up to 100W, as well as a relay output and an analog output channel。The addition of practical functions such as PID closed-loop control, Zone mode, variable temperature rate setting and active overheat detection makes the Kelvinion mini cryogenic thermostat an excellent tool for cryogenic research。
