    mini temperature controller

    mini temperature controller

    The "Kelvinion mini" from MultiFields is a compact cryogenic temperature controller with two independent high precision temperature measurement channels and a high power PID output of up to 100W, as well as a relay output and an analogue output. It consists of two independent high-precision temperature measurement channels and one high-power PID output channel up to 100 W, as well as a relay output and an analogue output channel. practical features such as PID closed-loop control, Zone mode, variable temperature rate setting and active overheat detection make the Kelvinion mini cryostat a powerful tool for cryogenic research.
