Digital Moisture Meter Manufacturer,Supplier and Exporter in India

The Digital Moisture Meter is a compact electronic tester for the water content of food grains, pulses, oil seeds and vegetable seeds. It works on the pressure principle, gives moisture values for around 15 commodities and keeps readings in its memory, so a class can log a series of samples during one practical.

Grain and seed practicals with the moisture meter

Drying curve. Read a freshly harvested sample, then dry it in a laboratory oven at a low setting. At fixed intervals, cool a sub-sample in a closed container and read it on the meter. Plotting moisture against drying time shows how quickly each crop gives up water.

Rapid test against a reference. Split one lot with a riffle sample divider so both portions match. Test one portion on the meter and the other on a moisture analyser, then discuss why the two values differ.

Moisture and germination. Record the moisture of each seed lot, count replicate lots on the Seed Counter and set them out in Petri dishes to germinate. Students then relate the moisture at storage to the germination count.

Store-room survey. Students draw samples from bags at the top, middle and bottom of a stack and log each reading in the meter. Comparing the stored values shows where damp grain collects and which bags need drying first.

Frequently Asked Questions About the Digital Moisture Meter

Why must the right commodity be selected before each test?

Each grain and seed packs and holds water differently, so the meter needs the setting for that crop. Reading wheat on a pulse setting gives a wrong value. Check the selected commodity every time the sample type changes.

Does the temperature of the sample affect the reading?

Yes. Grain taken straight from a dryer or a cold store can read differently from grain at room temperature. Let the sample settle in a closed container before testing, and follow the meter's own instructions on temperature correction.

How do students compare the meter with the oven method?

Divide one sample in two. Read one portion on the meter, then weigh, oven-dry and reweigh the other. Moisture on a wet basis is the weight lost divided by the fresh weight, times a hundred. The gap between the two figures shows how close the rapid test comes.

Why does pressing each sample the same way matter?

The meter works on the pressure principle, so a loosely filled chamber and a tightly packed one can give different values for the same grain. Fill to the same level and apply pressure the same way every time to keep readings comparable.

Why is moisture checked before grain or seed goes into storage?

Damp produce heats up, grows moulds and attracts insects in storage, and seed loses its ability to germinate sooner. Each crop has a moisture level below which it keeps well, so a reading shows whether a lot needs more drying first.

How should the meter be cleaned between commodities?

Empty the sample chamber after every test and brush out dust, husk and broken grain. Wipe away any oil left by oil seeds before testing a dry cereal. Store the meter in a dry place, away from damp store rooms.
