8 channel temperature controller

8 channel temperature controller

The Kelvinion is a powerful low-temperature thermostat。It includes eight independent high precision temperature measurement channels (supporting RTD and Diode type thermometers) and two high power PID output channels up to 100W+50W, as well as two relay outputs and two analog output channels。The addition of practical functions such as PID closed-loop control, Zone mode, variable temperature rate setting and active overheat detection makes the Kelvinion cryogenic thermostat an excellent tool for cryogenic research。
