RH6 Paper moisture meter with sword sensor for piles of paper.
The RH6 is also ideal for automatic monitoring of climate in printing rooms and paper storage rooms.
Paper moisture meter for relative and absolute moisture, temperature compensated paper and wood equilibrium moisture content, calibration curves for determination of water content.
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 interface 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.
Description of Definitions:
Relative air humidity: indicates the relation between the current water vapour pressure and the maximal possible water vapour pressure (called saturation vapour pressure).The relative humidity shows the degree the air is saturated with water vapour. For example:50% relative humidity indicates that at the current temperature and the current pressure the air is saturated with water vapour for half of its value, 100 % relative humidity means that the air is totally saturated. When the air has more than 100 % of relative humidity, the excessive moisture would condense or form fog.
Absolute humidity: shows the contained amount of water in grams per cubic metre of air. The absolute humidity is a direct degree for the amount of water vapour contained in a certain air volume. It shows how much moisture can maximally condense or how much water has to be evaporated to receive certain desired air humidity.
Dew point temperature: The dew point indicates the temperature that the not completely saturated air has to reach in order to be completely saturated with water vapour. If the room with the current relative humidity is cooled down to the dew point temperature, the water vapour begins to condense.
EMC wood: shows the equilibrium moisture content of wood (for timber stored under these conditions) in % moisture content of wood and the temperature in the selected unit (°C or °F).
aH kraftliner: shows the equilibrium moisture content of kraftliner paper (for paper stored under these conditions) in % moisture content and the temperature in the selected unit (°C or °F).
aH testliner: shows the equilibrium moisture content of testliner paper (for paper stored under these conditions) in % moisture content and the temperature in the selected unit (°C or °F).
empty curves: can be used to calibrate some special products
