MultiFields introduces the "Kelvinion Monitor", which comes standard with 12 independent, high-precision temperature measurement channels (RTD and Diode type thermometers are supported), each with a sampling rate of 10 SPS, and synchronised sampling between the channels with a sync time of better than 100 us. the master-slave design allows for easy expansion to up to 32 channels and support for mounting in standard cabinets. The master-slave design makes it easy to expand to a maximum of 32 channels and supports installation in standard cabinets.
In large cryogenic installations it is often necessary to check temperatures at several locations simultaneously, and for this need of multi-channel temperature measurement MultiFields has launched the "Kelvinion Monitor" cryogenic monitor. It comes standard with 12 proprietary, high-precision temperature measurement channels (RTD and Diode type thermometers), each with a sampling rate of 10 SPS and synchronised sampling between the channels with a sync time of better than 100 us. the master-slave design allows for easy expansion up to 32 channels and supports mounting in standard enclosures.
Features:
- Temperature measurement can be as low as 300 mK, the measurement resolution is as high as 0.1 mK (24-bit ADC).
- Standard configuration of 12 channels, and support for optional 2 ~ 32 channels;
- Each temperature measurement channel is independent of each other, the sampling rate are 10 SPS;
- Each channel is independent of each other, with a sampling rate of 10 SPS; the channels support synchronous sampling function, with a synchronisation time of better than 100us.
- Automatically adjust the excitation current of the thermometer to obtain the measurement accuracy and heat generation;
- Support 1000+ user-defined indexing table;
- Support USB (serial port), network port, RS485 communication mode.
