M series - miniature sensors

Humidity/-temperature compact sensors with cable or plug-in connection

These sensors are especially adapted to the requirements of measurement tasks which only have limited space available. They are suitable for measuring the relative humidity and temperature in air and other non-aggressive gases. Using the sensors for outdoor applications is not recommended.
The sensors are based on our miniature sensors in the calHT series (product info B1.10). They are fitted with a filter and a 4-pin plug (MCK...4S0) or with a permanently connected 1.5 m long cable (MC(P)K...1Kn). Suitable cables for the model MCK...4S0 can be supplied in different lengths as an option.
The sensors feature high long-term stability, small hysteresis and good dynamic performance.

User instructions


Install the sensors at a place in the room where characteristic levels of humidity occur. Avoid installing them close to heaters or windows or against outside walls.
In general, the sensors are maintenance-free. If the PTFE filter is contaminated with dust, grease and oils, this can have a negative impact on the dynamic behaviour. In this case the sensor head of the plug version needs to be disconnected from the cable and to be cleaned by blowing or carefully rinsing off with distilled water. After removing the filter, make sure that the sensitive sensor surface is not touched, as this can lead to irreparable damage. An exact measured value can only be attained again after being completely dried; this also applies to condensation.
Please consult „application instructions for the sensing elements“ (product info sheet no. A 1) for further information
