HM-GW grain freshness tester Introduction: The grain freshness tester is suitable for the grain industry standard of LS/T 6118-2017 "Grain and Oil Inspection - Determination and Discrimination of Rice Freshness", and is a specialized instrument for detecting the freshness of rice. The working principle is based on the amount of aldehydes and ketones produced during the aging process of the rice sample. The rice sample is ground into rice, and a special reagent - freshness measuring agent is added to the rice sample. After shaking and mixing, centrifugation treatment is carried out. The color change of the mixed solution after the reaction between the sample and freshness measuring agent is detected by the instrument, and the freshness value of the sample is displayed to determine the freshness of the rice sample. This instrument is mainly used in grain depots, rice processing enterprises, grain quality inspection centers, etc. to evaluate the freshness of rice. Features: 1. Android intelligent system version 7.1 provides a better interactive experience and is more convenient to use. 2. Adopting a precision rotary detection device with 12 detection channels, it can detect multiple samples in batches. 3. Supports WiFi and Bluetooth transmission, and data can be uploaded wirelessly; Supports copying data from USB drives without driver insertion and removal. 4. Configure a data platform, where detection results can be stored for long-term viewing and analysis, and assist in management. Technical parameters: Product composition: host, sample pre-processing components, and freshness testing agent; Measurement object: Rice (third grade rice that needs to be hulled and milled); Testing item: Can detect the FD value (freshness) of rice; Sample size for testing: 0.5-2g; Result expression: Freshness value; Measurement range: 0-100 points; Measurement time: ≥ 1min/12 samples; FD value repeatability: ≤ ± 2 points Working temperature: 18-25 ℃; Working humidity: below 80% (without condensation).
