Meatest M631 RTD simulator decadebank

The Meatest M631 RTD simulator decadebank has a high accuracy with a range of 16 Ω to 400 kΩ. This model has a basic accuracy of 0.01 °C, with a resolution of 0.001 °C. The decadebank consists of extremely stable film resistors, switched by means of relays. You can use the Meatest M631 as a RTD temperature sensor simulation (temperature setting in degrees Celsius or Fahrenheit) and as a standard resistance decadence bank. This instrument can be controlled via RS232, USB, LAN or GPIB interface. The decadebank uses an internal power supply with a very low noise level. The simulator can be used in AC applications. The standard frequency range is mentioned in the datasheet.

The RTD simulator is designed for calibration laboratories, for temperature testing of RTD evaluation units such as temperature controllers and transducers. With the resistance simulation function, the Meatest M631 can also be used as an ohimeter calibrator or used for quality testing in industry.
