Model GWJ-1 Grain Hardness Tester

The GWJ-1 grain hardness tester is specially designed for testing the hardness of grains (wheat, rice, rice, etc.) and adopts advanced force measurement technology. It has high testing accuracy, high instrumental visibility, high resolution, easy operation, and durability. specialty.

The performance of this instrument is better than that of PHARMA TEST. And it has a more beautiful appearance, you can buy on-site handheld measurement, but also can be rotated on the laboratory bench test. Its price is only 1/20 of imported instruments.

Suitable for scientific research and teaching in the agricultural industry.

1, the main technical features:

u hardness measurement pressure range 0~200N (0~20kg)

u Test accuracy ±5N (±0.5kg)

u resolution 0.1N (0.01kg)

u Determination of the maximum diameter of each item 18mm

u Dimensions (length × width × height) 140mm × 100mm × 250mm

u Weight (gross weight) 3kg

2, use method:

a. When testing small grains, use a photon to fix the grain (preferably upright), then rotate the handwheel to make the jack slowly pressurize and move forward. At this moment, the meter starts to indicate the pressure load and the pointer to the moment of grain crushing. Indicates the maximum number of pressures.

b. To retest, press the button on the instrument dial to start the next test. If the pointer does not point to zero, turn the circular dial so that the pointer points to zero and start the test.

3, reading method:

The big pointer is a 1kg walk, a small one is 0.01kg, and a big one is 0.1kg.

A small pointer to go is 1kg

The number of small hands is the measured number of kg

Measurement result = small pointer number + large pointer number

4, note:

(2) To avoid the impact of precision when used, wipe it clean.

(3) All parts of the instrument have been adjusted to the best condition. Do not disassemble the instrument.

5. Random list: one host, two height adjustment stations, one certificate, one manual
