 In designing this new collection of Semi-Standard PRT's (Platinum Resistance Thermometers), both the customers' needs and the equipment used were taken into consideration.
PRT's (Platinum Resistance Thermometers) are typically made in stainless steel sheaths which are 6mm in diameter, and have a Ro value of 100 ohms and an alpha [(R100-Ro)/Ro] of 0.00385. A variety of configurations are available, since particular characteristics might be required such as short sensing length, fast response, or applicability to a particular temperature range.
Most of our Semi-Standard PRT's (Platinum Resistance Thermometers) have been made longer and have a slightly wider temperature range. The stability of the semi-standard will depend upon its range of use and should remain within those uncertainties between successive annual calibrations.
These Semi-Standard PRT's are fitted with a handle and strain relief brushing for the cable, except where otherwise stated. They are all constructed with high-quality 100 ohm detectors and are assembled and calibrated using fixed point cells in-house in a NAMAS-approved and supervised laboratory.
