Temperature monitor

Temperature monitor

Kelvinion Monitor A low-temperature temperature monitor,It comes standard with 12 independent high precision temperature measurement channels (supporting RTD and Diode type thermometers), each with a sampling rate of 10SPS, with synchronous sampling between channels, synchronizing time better than 100us。The master/slave design allows easy expansion to up to 32 temperature measurement channels and supports installation into standard cabinets。

Temperature monitor product overview


In large cryogenic devices, it is often necessary to detect the temperature of multiple locations at the same time, so MultiFields introduced the "Kelvinion Monitor" cryogenic monitor for multi-channel temperature measurement。It comes standard with 12 independent high precision temperature measurement channels (supporting RTD and Diode type thermometers), each with a sampling rate of 10SPS, with synchronous sampling between channels, synchronizing time better than 100us。The master/slave design enables easy expansion to 32 channels for temperature measurement and supports installation into standard cabinets。


Product features:
- Temperature measurement can be as low as 300 mK with measurement resolution up to 0.1 mK (24-bit ADC);
- 12 temperature measurement channels are standard, and 2 to 32 temperature measurement channels are optional.
- Each temperature measurement channel is independent of each other, and the sampling rate is 10 SPS;
- Support synchronous sampling between channels. The synchronization time is better than 100us.
- Automatically adjust the thermometer excitation current to obtain measurement accuracy and heat output;
- Support 1000+ user-defined indexing tables;
- Support USB(serial port), network port, RS485 communication mode。
