humimeter PMZ cellulose moisture meter

Cellulose moisture measured in the stack of sheets

The humimeter PMZ is pushed in between the cellulose sheets and gives the absolute water content within seconds. The stack stays intact, so the measurement can be taken on goods ready for dispatch or on a delivery being received, with no sample cut out and no drying oven.

What it measures

cellulose sheets in stacks and bales
bleached and unbleached cellulose
pulp in sheet form
other sheet materials, once a curve has been worked out in the manufacturer’s laboratory

The measuring range of 6 to 40 % water content covers both commercial cellulose at normal moisture and material that has taken up water in transport.

Advantages

non-destructive measurement, the stack stays fit for dispatch
a 300 mm sensor blade reaching into the stack
a removable cross handle that makes the blade easier to push in
resolution 0.1 % water content
automatic temperature compensation
automatic and manual data logger for 10,000 readings with a measuring point report
wooden case included
a result in seconds, with no sample preparation

How the measurement is taken

Take the instrument by the cross handle and push the sensor blade in between the sheets over its full length.
Read the water content from the backlit display.
Repeat at several points of the stack: moisture can differ between the edge and the middle of a bale.
Store the readings with the measuring point description if the result is going into receiving or dispatch documentation.

Where it is used

pulp mills - checking the product before dispatch
paper mills - incoming control of delivered cellulose
pulp trading - settling a batch in which water weighs as much as fibre
warehouses and forwarding - checking whether a batch has taken up moisture in transit

Scope of delivery

humimeter PMZ with rubber protection cover
removable steel cross handle
wooden case
batteries

The USB interface module with the LogMemorizer software is not included: it is a separate item, art. no. 12278, or 14957 in the battery version.

Checking the readings

Test block art. no. 12308 gives a quick check that the instrument still measures as it did on the day it was calibrated. Independently of that, it is worth comparing a reading with the drying-oven result from time to time.

PMZ or another paper moisture meter

The PMZ is made for cellulose sheets in a stack and gives the absolute water content. For paper and solid board in a stack there is the humimeter PMP, selected by the density of the paper; for waste paper bales the humimeter RP6, measuring to a depth of 500 mm; and for the equilibrium moisture content in a stack of paper the humimeter RH5 with its sword probe.
