What is a Digital Moisture Meter and how does it work?
A Digital Moisture Meter is an electronic laboratory and field instrument used to measure the moisture percentage in agricultural produce. National Instruments meters operate on the impedance measurement principle, calculating the dielectric constant of materials with an accuracy of 0.2% as per IS-8824 standards.
Which commodities can be tested with National Instruments moisture meters?
Over 60 commodities can be tested across 10 categories including Oilseeds (Soya bean, Mustard, Groundnut, Castor, Till), Grains (Paddy, Wheat, Maize, Bajra), Pulses & Dal (Chana, Toor, Mung, Urad), Vegetable Seeds, Spices Whole, Dry Fruits, Fryums, Cakes & DOC, and Flours.
Is the sample testing non-destructive?
Yes, National Instruments moisture meters use non-destructive sample testing. You pour the 150g (250 CC) sample into the hopper, obtain the reading within 40 to 60 seconds, and pour the sample back out completely intact.
What is the difference between DMM and DMA series?
DMM is the regular series featuring an LCD display and standard moisture readings. DMA is the advanced series featuring a 16x2 LCD display, microcontroller, auto calibration check (Press 5+7), personalised display text, service indication, and empty cavity reading of 0.0%.
How fast is a single moisture reading?
A complete moisture measurement takes under 60 seconds per sample (1 sample per minute), allowing rapid testing of multiple bags in godowns, mandi markets, and processing plants.
Are National Instruments moisture meters compliant with Indian Standards?
Yes, all DMM and DMA series models are calibrated and tested in accordance with IS-8824-Part-I-1978 specifications.
