Overview
Product Details
WGZ series of scattered light turbidity meter is used for measuring suspended in water or in transparent liquids insoluble particulate matter produced by scattering, and quantitative standard to the suspended particle matter content. Can be widely used in power plant, the pure water plant, water plant sewage treatment factory, beverage factory, environmental protection departments, industrial water, wine making industry and the pharmaceutical industry, hospitals, epidemic prevention departments and other departments of the determination of turbidity.

ZD Series scattered light turbidity meter is a combination of photoelectric precision measurement instruments, should read the instructions carefully before operating and obtain accurate results through action to correct.1. Environmental working conditions must be met.2. measuring cell must be clean and dry for a long time, no dust shall cover shielding cover when not in use.3. humid climate, it must be extended boot time.4. test solution should be carefully poured along the sample bottle, to prevent bubbles affect the measurement accuracy.5. Replacing the sample bottle or to be re-calibrated after repair.6 .Non-professional maintenance engineers, do not open the instrument for maintenance.
1. The instrument should be placed in a dry room, temperature 5 ℃ -35 ℃.2 .should be placed on a flat work surface, and to avoid vibration.3. indoor lighting should not be too strong, and avoid direct sunlight irradiation.4. as far away from high-intensity magnetic field, electric field and the occurrence of high-frequency waves of electrical equipment.5 .Avoid high temperatures close to the instrument.6. Power supply Instruments: 220V ± 22V, 50 ± 1Hz, and must have a good grounding wire.
5Measurement preparation1. Switch on the instrument's power switch;2 .does not drop the hair soft cloth to wipe the water marks and fingerprints on the sample bottle, available as easy to wipe soaked in detergent and then rinse with water;Formazin turbidity standard solution ready for school
3. petty zero turbidity water and preparation of calibration4. with a good clean container collected a representative sample;
