This equipment is used to quickly measure the moisture percentage in paper / paperboard / corrugated boards. The Instant Moisture Meter is an electrical resistance-type moisture meter, utilizing the relationship between moisture content and electrical resistance. The contact pins mounted on the top of the meter are used for making direct contact with the material.
Note :
Instant Moisture Meters (of any brand / make) should be used for approximation only. Instant Moisture Meters measure the electrical resistance between the contact points (probes), hence they will measure only the maximum moisture % at contact point. If you use any Flat Probe Type unit, it will show the Surface Moisture only. If your use any Pin Probe Type unit, it will show the maximum moisture across the point of penetration. NO INSTANT MOISTURE METER IN THE WORLD can show the MOISTURE CONTENT of the sample Paper / Board, etc. The Surface Moisture / Instant Moisture readings will vary from the Moisture Content value of the sample. This instrument is OK for quick checks under stabilized conditions or for testing paper. For the most authentic Moisture Content analysis, use a Moisture Oven or Moisture Analyser which works on the LOSS ON DRYING principle and is the only recommended method as per TAPPI standards.
