To prevent the RH5 and probe from being damaged when used in heave stacks of paper there is an optional protection sleeve available as well as a sleeve removal tool. The sleeve can be inserted into a stack or pile of paper after which the RH5 is attached to it. Measurements can then be taken without measurement outcomes being distorted. After you are finished you can remove the RH5 probe from the stack with a special "probe removal tool".
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 calibrated range of the RH5 hygrometer is 10% to 90% relative humidity, and when the probe is used this is related to the moisture content in the paper stack. Naturally the device can also be used for normal relative air humidity measurements.
Alternatively the actual air humidity or dew point temperature on the probe (sword) tip can be measured.
The model RH5-USB is equipped with a USB interface for data transfer. This model includes software and a data data transfer cable for connection to a PC or printer. A portable thermal printer is available that can be used to print measured values directly from the instrument.
