Water quality transparency measurement equipment
JN-TMD330
Testing item (water quality transparency)
1、 Product Introduction
Water quality transparency measurement equipmentJN-TMD330 is made of organic glass, with a transparency meter of 330mm in length and 25mm in inner diameter. It is a colorless organic glass cylinder engraved with a 10MM scale and has a white porcelain tile at the bottom (with a black cross or black E inside).
2、 Operation steps
1. Transfer the thoroughly mixed water sample to a transparent cylinder and fill it up,
2. Observe vertically from the mouth of the pipe with your eyes, while turning on the switch at the lower outlet. Stop draining when you can just recognize the black cross shape at the bottom.
3. Record the height of the water column (CM).
4. Repeat the above steps twice and take the average.
5. Result calculation: Transparency=Water column height (CM), recorded to the nearest 10MM.
3、 Precautions
1. Water samples with a high concentration of suspended matter may sometimes experience sedimentation at the bottom of the transparency meter, which is a cause of error and should be noted.
2. Lighting conditions should be as consistent as possible. The light source should be white light in principle, avoiding direct sunlight.
3. Differences in vision can cause deviations in the measured values, so it is best to choose a tester with normal vision and take the average of multiple or multiple measurements.
Water quality transparency measurement equipmentIt is one of the important equipment for monitoring the treatment of black and odorous water. Black and odorous water monitoring equipment also requires three parameter monitoring equipment for black and odorous water quality, such as ammonia nitrogen detectors and dissolved oxygen detectors.
According to the needs of rural black and odorous water treatment work, the current water quality status can be monitored, including main water quality indicators such as transparency, dissolved oxygen, and ammonia nitrogen; When necessary, selective investigation of indicators such as total nitrogen, total phosphorus, chemical oxygen demand, and fecal coliforms can be conducted.
