Use of online residual chlorine detector

Precautions for the use of online residual chlorine detector The online residual chlorine detector is composed of a residual chlorine sensor and a residual chlorine meter. It can measure residual chlorine and temperature at the same time. It is widely used in electric power, water supply, medicine, chemical industry, food and other industries. Continuous measurement of residual chlorine in water. 1. The user should use the manufacturer's supporting residual chlorine (total chlorine) DPD reagent when measuring the instrument. 2. If the temperature of the water sample is lower than 15°C, it should be preheated to above 15°C after adding the drug (wrap the sample cell with a layer of paper and shake it with your hands), until the drug is completely dissolved, and then measure. 3. Sampling samples must be analyzed immediately and cannot be stored for later analysis. 4. When the sample cell is inserted into the sample cell slot, the sample cell must be correctly positioned and locked (the sample cell is placed in the sample cell slot, so that the triangular mark on the bottle cap is aligned with the triangular positioning mark on the instrument) to prevent stray light Enter. After the sample cell is installed in the sample cell tank, it should be kept still for at least 30 seconds (to allow the air bubbles in the sample to be eliminated and the solid particles to settle) before measurement. 5. After one measurement (residual chlorine or total chlorine measurement), the sample cell must be thoroughly cleaned before using the same sample cell for another measurement. 6. The sample cell and bottle cap must be cleaned immediately after measurement to prevent contamination and corrosion of the sample cell. 7. If solid or solution enters the sample cell, it must be cleaned before being put into the sample cell. When the 'READ' key is pressed continuously, if the reading increases or the reading is unstable (nearly before '- - - L' appears), it means that the battery voltage is insufficient, and the battery should be replaced and measured again. 8. The standardization of the time used to control each step is crucial to improving the precision of the determination. The color development can be stable for about 5 minutes at a concentration of 0.5 mg/L, and the color development can be stable for about 2 minutes at a concentration of about 2.0 mg/L. 3.0 The color development at a concentration of about mg/L can be stable for about 1 minute. 9. When the concentration of the water sample to be measured is greater than the measuring range of the instrument, the reading of the instrument will overflow and cannot be read. At this time, the water sample to be tested should be diluted to an appropriate concentration with distilled water or deionized water for measurement. The concentration value of the tested water sample is calculated according to the following formula: The concentration of the tested water sample = instrument reading × dilution ratio
There are many issues that affect water quality monitoring device, which has led to the need of getting specialists trained in certain areas so as to handle all issues that may arise as well as water analyzer products that can solve water quality monitoring device problems.
The 21st century is sure to bring more innovation, new services and newer technology, thus new products and services to sell. Shanghai Boqu Instrument Co., Ltd. will continue to shape and lead the markets in which it chooses to compete.
These water quality monitoring device water analyzer are not only useful but also more cost effective than those traditional ones.
