The main requirement of a reference probe is stability. This means minimal drift as a function of operating time at the actual temperature. The less the probe drifts, the lower the measurement uncertainty.   Especially for the ETC-400 R calibrator JOFRA has designed a special 3 mm STS reference sensor, the STS-103 B. The sensor can be used as a reference sensor when a higher accuracy is required or for recalibration of the ETC-400 R. Due to the small immersion depth requirement of the sensor it can be placed under the surface of the target.
