 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.
