Semi-standard PRTs are typically made in stainless steel sheaths which are 6mm in diameter,
and have an 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 PRTs have been made longer, and have a slightly wider temperature range.
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.
These sensors are ideal for a comparison reference sensor in industrial and secondary laboratories.
