Kelvinion Monitor Temperature Monitor

Brand：MultiFields

Model : Kelvinion Monitor

Q'ty :

For the multi-channel temperature sensing requirements in large cryogenic setups, MultiFields introduces the Kelvinion Monitor cryogenic monitor. It allows users to select the number of measurement channels, each independent and compatible with RTD, Diode, and thermocouple thermometers. Each temperature measurement channel features a sampling rate of 10 SPS, with inter-channel synchronous sampling capability—synchronization time is better than 100 μs. The master-slave design enables easy expansion to up to 32 temperature measurement channels and supports installation in standard racks.
