This instrument is developed in accordance with the requirements of the clarity tester device in the standard GB/T 18712-2002 "Test Method for Performance of Flocculants for Coal Preparation". For coal slurry in coal preparation plants, the performance of flocculants is reflected in differences in sedimentation speed, supernatant clarity, and sediment volume. The flocculant solution is added to a measuring cylinder containing coal slurry, mixed, and an interface is formed between the supernatant and flocs. The free sedimentation speed (or initial sedimentation speed), supernatant clarity, and sediment volume are measured to characterize the performance of the flocculant.
I. Main Features of YJH-18712 Supernatant Clarity Tester
1. The traditional timing dial code is removed, replaced by chip integrated control, with full-touch keys, making operation simple and convenient, and the service life of the instrument is increased by 3 times.
2. Users can calibrate the instrument's illuminance by themselves according to a standard illuminance meter, which adds a self-calibration function.
3. The length of the bottom whiteboard is increased, enabling side-by-side detection of supernatants.
4. The detection lamp tube is upgraded to an Aji precision lamp tube, with a service life 2 times that of traditional lamp tubes.
5. A voltage stabilization control circuit is added, and the detection optical path system eliminates stroboscopic effect. The illuminance is adjustable, improving visual resolution and reducing eye fatigue.
6. A digital electronic illuminance meter is adopted, with intuitive and stable readings. The detection time can be set arbitrarily, and it has an audible and visual alarm function.
7. The light source illuminance index, black background and detection whiteboard of this instrument all meet the standards.
8. The optical path system composed of dedicated tri-color fluorescent lamp, electronic ballast and light-shielding device is adopted, which eliminates stroboscopic effect, improves visual inspection resolution and reduces eye fatigue.
9. The illuminance is adjustable, and the digital electronic illuminance meter has intuitive and stable readings.
10. The instrument has a reasonable design, stable performance, simple operation and beautiful appearance.
11. Black numbers are engraved on the inner wall of the test container.
