Moistrex MX8000

Moistrex MX8000 Paper Moisture Analyzer

Overview

The Moistrex MX8000 benchtop moisture analyzer provides fast and accurate moisture measurement of paper samples. The instrument only measures the water-bound to the cellulose fibres and is insensitive to printing, surface treatments and plastic laminations. Since the instrument uses microwave technology to measure moisture, polythene and plastics do not affect the measurement. Therefore paper samples can be stored in polythene bags and presented to the MX8000 for measurement. This preserves the integrity of the samples and prevents moisture conditioning between the sampling point and measurement. The device is delivered pre-calibrated and ready to use for instant results.

Quick Spec

Model Paper weight range Moisture range Accuracy
MX8000-T80 30-400 gms 0-15% ±0.1% moisture content
MX8000-T20 150-1200 gms 0-15% ±0.1% moisture content

Operating Principle

The MX8000 incorporates a waveguide down which a microwave signal is transmitted. When a paper sample is inserted, the waveguide is split into two. The water molecules within the paper or board sample attenuate the microwave signal which is proportional to the amount of water in the paper. The detector measures the microwave loss and converts this signal into a percent moisture value. The measurement is unaffected by colour printing, surface finish or sizing. Because the measurement technique measures through the paper or board sample, it is unaffected by any moisture stratification.

Applications

The instrument is used in for all types of paper and board products such as newsprint, tissue, towelling, corrugating, liner and board products where rapid and accurate moisture measurement is required.
