humimeter RH5.1 hand-held paper hygrometer with sword probe

Art. No.: 11994 humimeter RH5.1 Paper hygrometer with sword probe


The humimeter RH5.1 hand-held Paper hygrometer with sword probe is a powerful moisture tester with sword probe (see picture) for moisture measurement in paper stacks.  To determine humidity, the sword sensor only has to be inserted into the paper stack and left there for a short conditioning time.  The paper moisture tester will display results within a few seconds.

Via the integrated datalog the measuring results can be stored on the RH5.1 paper moisture tester and additional data can be added.
In order to prevent a damage of the sword sensor when using the RH5.1 paper moisture tester in heavy paper stacks, a sword sensor holder and a tool for removing the sword sensor holder are available optionally. Before inserting the probe, the sword sensor holder is driven in the paper stack and enables a measurement without any falsification of the measuring value. For an easy removal of the sword sensor holder after drawing out the RH5.1 Paper hygrometer with sword probe, the tool for removing the sword sensor holder is used.

Simultaneously, the paper moisture tester also measures the material temperature and includes it in the calculation of the measuring result. The temperature range goes from -10 °C to +60 °C and can be set to °C or °F as required.

The calibrated measuring range of our RH5.1 Paper hygrometer with sword probe goes from 10 % to 90 % relative air humidity. Using the sword sensor in a paper stack, the air humidity equates to the paper moisture. Naturally, the RH5.1 paper moisture tester is also suited for determining the air humidity in a room.
