The "Kelvinion" from MultiFields is a powerful cryogenic temperature controller. The Kelvinion is a powerful cryogenic thermostat that includes two independent high-precision temperature measurement channels (RTD and Diode type thermometers are supported) and two high-power PID outputs of up to 100W+50W, as well as two relay outputs and two analogue output channels. Kelvinion cryostat is a great tool for cryogenic research.
