Heraeus MR Series Platinum Elements

Heraeus MR series sensors are flat thin-film platinum elements housed in a round ceramic body.  This circular design can aid sensor assembly or it’s possible to have an extra sensing element (in the duplex version) to have built-in redundancy.

Two probe diameters (2.8mm and 4.5mm) are available with Pt100, Pt500 and Pt1000 options depending on the size chosen.  Duplex versions are also possible with the Pt100 and Pt1000 sensor elements.
