Product
The MK33 Mini is the miniaturization of the well proven MK33 sensor. Using the MK33 polymer on a minimal
sensor surface this sensor exhibits a signal ouput comparable to the P14 and simultaneously brings the best in
chemical resistance at an affordable price.

Advantages
High chemical resistance
Wide temperature operating range (up to +190 °C)
Hot water resistance
Condensation resistant – fast recovering time after dewing,
and at high dew point temperatures as well
High humidity stability
