These resistance temperature probes S 33/250 are designed for contact measurement of solid sustances with flat and smooth surface. The temperature range for the use of the probe is -30 to 150 °C. The probes consist of a metal case terminated by a special cup to contract the measured surface, a handle and a lead-in cable. The resistance sensing element is located in a brass (duralumin) sup, which is firmly placed in a special rubber case reducing the influence of the surrounding environment on the measurement.

The temperature probes are intended for operation in chemically non-aggressive environment.


  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
