RH5 Paper Moisture Meter
Click images to enlarge.
The RH5 Paper Moisture Meter is designed for measuring relative moisture in paper by inserting the sword probe into a stack/pile of paper. The measured values can be manually entered into datalogger or can be set to automatically record at pre-set intervals

The temperature is measured as well and included in the hygromeasurement. Temperature range for measurement is -10 to +60 °C and can either be displayed in °C or °F. The RH5 hygrometer can measure the relative air humidity measurements or dew point.

Model RH5-USB includes USB output for transferring recorded data to a PC or printer for analysis/documentation. It is supplied with FREE software and USB data transfer cable for connection to a PC. There is also an option for a thermal printer with which you can print you measured values without a PC directly from the instrument. For additional protection, we recommend the optional RH-SWORD sensor holder to prevent the sensor or gauge being damaged during the "insertion" process. We also recommend using the optional RH-REMOVE removal tool to extract the sensor holder from the stack of paper.

RH5 Measuring procedure

To determine the moisture in paper piles, the sword sensor is inserted into the paper stack and left there for a short conditioning time. The large, well-lit display shows the current moisture and temperature value. Via the integrated datalogger the measuring values can be stored and additional data can be added. The Autolog function enables an automatic saving of measuring values in adjustable time intervals. To prevent a damage of the sword sensor in heavy paper stacks, a sword sensor holder and a tool for removing the sword sensor holder are available optionally. The humimeter USB data inter-face module offers the possibility to connect the device to a PC. Via the delivered LogMemorizer software the measuring values can be read off the device, addition information can be added, and the data can be archived, exported and processed.
