Meatest M641 programmable RTD simulator

The Meatest M641 is a programmable RTD simulator with a range of 10 Ω to 300 kΩ. This model has a basic accuracy of 0.1°C and a resolution of 0.001°C. The simulator consists of “High load” resistors, switched off by relays. The Meatest M641 can be used as RTD temperature sensor simulation (temperature setting in degrees Celsius or Fahrenheit) or as a standard resistance decadebank.


This instrument can be controlled via RS232, USB, LAN or GPIB interface. The RTD simulator has been developed for use in industry as a device for temperature testing of RTD evaluation instruments, such as temperature controllers and transducers. With the resistance simulation function, the M641 can also be used as an ohimeter calibrator or used for quality testing in industry.
