The YJH-18712 Supernatant Clarity Tester is an instrument developed in accordance with the requirements for clarity testing devices specified in the standard GB/T 18712-2002 "Test Methods for Performance of Flocculants Used in Coal Preparation". For coal slime water in coal preparation plants, the performance of a flocculant is manifested in differences in settling velocity, supernatant clarity, and sediment volume. The flocculant solution is added to a graduated cylinder containing coal slime water, mixed, and an interface is formed between the supernatant and flocs. The free settling velocity (or initial settling velocity), supernatant clarity, and sediment volume are measured to characterize the performance of the flocculant.
I. Main Features
1. The traditional timing dial switches are removed, replaced by chip integrated control, with full-touch keys, making operation simple and the service life of the instrument increased by 3 times.
2. Users can calibrate the illuminance of the instrument 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 the supernatant.
4. The detection lamp is upgraded to an Aji precision lamp, with a service life twice that of traditional lamps.
5. A voltage stabilization control circuit is added, the detection optical path system eliminates stroboscopic effect, the illuminance is adjustable, the visual resolution is improved, and visual fatigue is reduced.
6. A digital electronic illuminance meter is adopted, with intuitive, stable and reliable readings, the detection time can be set arbitrarily, and it has sound and light alarm functions.
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 a dedicated tri-color fluorescent lamp, electronic ballast and light-shielding device is adopted, which eliminates stroboscopic effect, improves visual inspection resolution and reduces visual fatigue.
9. The illuminance is adjustable, and the digital electronic illuminance meter has intuitive, stable and reliable 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.
