Temperature Meter, Probe, and System Calibrations
For many types of thermometry probes your application requires, Tra-Cal can ensure the accuracy of your meter, probe, or system!
| NIST-traceable report for: | Description |
|---|---|
| Thermocouple, standard types | Four test points across range of instrument. Meter: –270 to 2316°C (–454 to 4200°F); Probe and System: –80 to 1300°C (–112 to 2372°F). Actual range is dependent on type of probe. |
| RTD | Four test points across range of instrument. Meter: –200 to 1000°C (–328 to 1832°F); Probe and System: –80 to 1300°C (–112 to 2372°F). Actual range is dependent on type of probe. |
| Bimetal or dial | Four test points across range, –197 to 1000°C (–320 to 1832°F) |
| PRT probe or HART® style meter and probe | Four test points across range of instrument. Meter: –270 to 2316°C (–454 to 4200°F); Probe and System: –80 to 1000°C (–112 to 1832°F). Actual range is dependent on type of probe. |
