The RH5.1 stick hygrometer is a powerful moisture meter with sword sensor for moisture determination in paper stacks. In order to measure the moisture in a stack of paper, this sensor only has to be guided into the stack and there for a short adjustment time .

The measured values can also be stored via the data logger of the Humimeter RH5.1 lancing hygrometer, provided with additional data and called up again later. In order not to damage the sword when working with heavy paper stacks, the sword sleeve and the sword sleeve extractor are available as accessories. The sword sleeve can be driven into the paper stack, then the Humimeter RH5.1 lancing hygrometer is inserted into it and the measurement is taken without falsifying the result. At the end of the measurement, the device is pulled out of the sleeve and this can be easily removed from the stack with the sword sleeve extractor.

At the same time, the Humimeter RH5.1 lancing hygrometer also measures and displays the temperature of the material and also includes it in the moisture calculation. The measuring range for this is -10 to +60 °C, 14 to 140 °F, resolution 0,1 °C and can be displayed optionally in °C or °F.

The calibrated measuring range of our humimeter RH5.1 lancing hygrometer ranges from 10% to 90% relative humidity. Of course, the device for paper moisture can also be used to measure to normal humidity in a room.
