Laboratory turbidimeters can be used to measure the turbidity of raw or purified water on filtration devices in various places, such as drinking water, various production and industrial waters, and wherever qualified water is required
.
The product is compact in structure, with built-in backlight LCD screen, data storage, and relay control output (3 channels)
.
The turbidity controller outputs a 4~20mA isolated signal to transmit reliable data wherever turbidity needs to be monitored and controlled
.
Built-in microprocessor, configuration, powerful functions, is a very turbidity measuring instrument, based on the 880nm infrared light source through the optical lens and penetrating the sample liquid, according to the ISO7072 standard to measure the scattered light in the 90° direction, Beijing Tianyu Water Instrument Relevant personnel of Science and Technology Co.
, Ltd.
suggest that the following 6 points should be paid attention to when using the laboratory turbidity meter: 1.
Measure the other position difference (cylinder difference) of the two sample cups, and make the corresponding turbidity measurement values in the future samples.
Correction
.
2.
If the selection key of "Range" needs to be changed during the measurement, except for the selection of different cuvettes, the zero-adjustment step for turbidity-free water must be repeated once
.
3.
If there are few samples to be measured, the same cuvette can be used for zero calibration and sample measurement, so that the old cuvette will not be brought into the cylinder, which is beneficial to the reliability of test data and avoid unnecessary operation errors
.
4.
When using an old cuvette to hold the sample and add "0" water during measurement, it must be put into "0" water at the same time before the sample is tested
.
5.
Carefully check the turbidity standard plate.
If there is dust or stains, it can be wiped off with absorbent cotton, ethanol and a half mixture of acetaminophen.
The cuvette can be cleaned with detergent or detergent, and then rinsed with clean water.
Dry face
.
Warm up the instrument for 10 minutes
.
6.
During the measurement, the two optical paths of the cuvette must be free of any dirty spots, and there must be no water stains on the two sides and bottom
