Platinum Resistance Temperature Detector
MH 220
Mseries PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy over
a large temperature range are vital. Typical applications are Automotive, White goods, HVAC, Energy management,
Medical and Industrial equipment.
