ST128 Electronic (grain) capacitance meter

Grain bulk density refers to the weight of grains per unit volume. It is a core indicator for evaluating the quality, fullness and grade of grains, directly affecting the purchase pricing, storage stability and processing value of grains. Generally, the higher the bulk density, the plumper the grain particles and the better the quality.

The determination of bulk density of grains is a key link in the fields of grain purchasing, storage, processing and quality inspection. By precisely measuring bulk density, the maturity and impurity content of grains can be quickly judged, providing a scientific basis for grain quality control and trade settlement.

The ST128 (HGT-1000) electronic grain bulk density tester is a new type of grain quality inspection instrument developed in tandem with the research and formulation of the new national standard for corn, and it complies with the GB/T 5498-2013 "Determination of Bulk Density in Grain and Oilseed Inspection" standard. It can not only measure the bulk density of large-grain grains such as corn, but also that of small-grain crops like millet, wheat and sorghum, and is suitable for the bulk density determination of multiple varieties of grains.

This instrument is an intelligent weighing device equipped with a microprocessor. It features reliable performance, convenient operation and high precision. The results are displayed on a red LED digital tube. Data can be printed through a randomly configured printer or connected to a computer via an interface. Its main technical indicators are as follows:

- Maximum working weight: 1000g±2g
