About: In 2009, we introduced our Compact Grain Moisture Meters, reducing the weight from 22 kg (of existing Universal Moisture Meter models ) to just 12.5 kg. This redesign made these moisture meters more portable and easier to handle, while still retaining the critical advantage of the test cup being visible during operations. With the reduced weight and size, our compact Moisture Meters offer the perfect blend of portability and ease of use. This also helped in reducing the moisture machines price. With just one switch, it reduces the chance of mistakes, making it perfect for quick moisture checks, even for less experienced users. The design of this model is registered under number 225286, dated October 12, 2009.
Application:These Compact moisture meters are highly popular in the milling industry and are widely used in dal mills, rice mills, flour mills, grain warehouses, seed companies, and government procurement agencies.
Construction: These new compact digital moisture detector models feature main bodies made from a special alloy steel, while the test cup, top plunger, bottom plunger, ratchet handle, and crank handle’s body are constructed from stainless steel. In this design the Top plunger is fixed and the Test Cup moves upwards to compress the grain sample. The thickness is measured on the linear vertical scale ( main division ) and the dial ( sub division) on the side of the meter. The mechanical components including buttress thread lead screw, bevel gears, main body, plungers etc of these moisture meters are manufactured by CNC machining process to very high precision to ensure interchangeability.
Working Principle: Digital moisture meter 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:Indosaw moisture meters feature a single switch for easy operation. 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 switch is pressed to display the moisture content on the LED display of the rapid digital moisture meter.
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.
