Description
The STS050A350DH is an STS-050 reference sensor in variant A with a 350 mm probe, configured with order suffix DH. The JOFRA STS series from Ametek are Pt100 reference temperature sensors built to serve as the measurement standard during temperature calibration. Placed in a dry-block or liquid bath next to the sensor under test, the probe reports the true block temperature to a JOFRA calibrator with a reference input, so the comparison does not rely on the source’s internal control sensor alone. Calibration labs, instrument shops and plant maintenance teams use them to calibrate RTDs, thermocouples, thermometers and temperature switches.
Key features
- Pt100 platinum resistance element with specified low drift
