Hermetically Sealed
PT100 Resistance Thermometer Probe
Originally designed to service the requirements for a robust PT100
resistance thermometer for use on skid mounted or portable process
plant within the pharmaceutical industry.
The assembly utilises an aerospace/military style of connector which
enables the probe to be left in position during CIP procedures or whilst
undergoing sterilisation cycles.
