About: Since 1993, we have been manufacturing Agro-body Grain Moisture checking machines. Weighing approximately 9.5 kg, these meters are significantly lighter than other 30 cc sample volume models, enhancing portability. They are calibrated for Cereals, Pulses, Millets, Oil seeds, Vegetable seeds, coffee seeds. Highly popular across the milling industry, our moisture meters are widely used in Dall mills, Rice mills, Flour mills, Grain warehouses, Seed companies, and government procurement agencies. This model also has a real time data logging facility.
Application: These are commonly referred as moisture meters for paddy, rice moisture meters, maize moisture meters and seed moisture meters, they offer trusted performance and reliability.
Construction: In these Agro Body moisture meter models, the main body is made from mild steel plates, while the test cup, ratchet handle, and crank handle’s body are constructed from stainless steel. Pressure is applied via a top plunger, while the test cup remains stationary during moisture measurement. The thickness is measured using a linear vertical scale (main division) and a round dial (subdivision) on the top of the meter. The mechanical components, including the buttress thread lead screw, bevel gears, main body, and plungers, are manufactured with high precision using CNC machining to ensure interchangeability
Working Principle: Agro body digital moisture meters for grains operate on the principle that the electrical resistance of grains changes with moisture content. A table is programmed into the microcontroller to map the relationship between moisture content and resistivity constant. Additionally, they are programmed to compensate for temperature variations, ensuring precise moisture measurement for grains.
Operation: These moisture meters feature a membrane keypad for selecting commodities and navigating menu options. To operate, a fixed volume of grain (about 30 cc) is measured using the provided volume cup and transferred to the stainless steel test cup. High pressure is then applied to compress the grain to a predetermined thickness, after which the read switch is pressed to display the moisture content on the LCD screen of the digital moisture meter tester.
Standards: The accuracy, repeatability, and reproducibility of this machine meet BIS (IS-8824 Part 1: 2022) and international standards. Indosaw now has an in-house NABL-approved (ISO 17025: 2017) moisture testing lab for IS-4333 (Part 2: 2017) to verify the results of our grain moisture meters.
