Turbidity measurement device WGZ Series dispersive optical turbidity gauges are used to measure the degree of light scattering from insoluble particulate matter suspended in water or transparent liquids, and to characterize the problem of suspended grain content in these substances. Turbidity measurement device can be widely used in power plants, water plants, domestic sewage treatment stations, beverage plants, environmental protection departments, industrial water, alcohol, pharmaceutical industry, turbidity measurement, popular prevention departments, hospitals and so on.
turbidity measurement device
Minimum Readout ( NTU)
Bench top type
1, zero turbidity water poured into the sample bottle to the scale line, then screw on cap, and clean the bottle water trace and fingerprints, it should be noted that the open not available when the hand directly with the bottle body, so as not to leave fingerprints, affect the accuracy of measurement.
2, will be packed with zero turbidity water sample bottle, into the sample holder, and to ensure that the specimen bottle scale line with quasi specimen holder white line of position, and then covered with a shading cover.
3, wait for stable after adjusting zero adjusting knob, so that the display is zero.
4, the same device calibration using 100NTU standard solution, and is placed in the sample holder, adjustment knob, so that the display as the standard value 100.
5, 2, 3, 4, repeat steps, to ensure zero and calibration values are correct and reliable.
6, into the sample bottle, and stable to note the water turbidity value.
1,after starting up, display
A、power line and socket connection is bad or loose
A、fastening socket or for power line
A, light damage
B, internal connector loose
C, electrical system fault
3,measurement instability or drift
A, solution with bubbles or particles in does not stop moving
