Installation environment of online conductivity detector
The online conductivity detector can continuously measure and control the conductivity (TDS) value of various industrial water. This device is widely used in scientific experiment equipment, chemical industry, pharmaceutical, environmental protection, metallurgy, papermaking, food, beverage and water supply industries. . Equipped with high-performance and high-precision electrodes, it can achieve high-precision detection of target water bodies, and has strong adaptability, longer service life, and simple maintenance. The product is equipped with a data display screen, and the conductivity data of the water body monitored by the electrode will be displayed on the screen. The data is clear and clear at a glance. Conductivity is a numerical representation of the ability of a solution to conduct electric current. The conductivity of water has a certain relationship with the amount of inorganic acid, alkali and salt contained in it. When their concentration is low, the conductivity increases with the increase of concentration. Therefore, this index is often used to infer the total amount of ions in water. concentration or salt content. The unit of conductance of online conductivity detector: the basic unit of conductance is Siemens (S), which was originally called mho, which means the reciprocal of the resistance unit ohm. Because the geometry of the conductivity cell affects the conductivity value, the standard measurement uses the unit S/cm to express the conductivity to compensate for the difference caused by various electrode sizes. The unit conductivity (C) is simply the product of the measured conductance (G) and the conductivity cell constant (L/A). Here L is the length of the liquid column between the two plates, and A is the area of the plates. Precautions for the use of online conductivity detector: 1. The meter should be placed in a dry environment to avoid leakage or measurement errors caused by splashing of water droplets or damp. 2. The electrodes should be regularly calibrated; the electrode socket should be protected from moisture to prevent unnecessary measurement errors. 3. In order to ensure the measurement accuracy, the electrode should be rinsed twice with distilled water (or deionized water) less than 0.5μS/cm before use (the platinum black electrode must be soaked in distilled water for a while after it has been dried for a period of time), and then used The test sample was washed three times before measurement. 4. Do not use strong acid or alkali to clean, so as not to change the electrode constant and affect the measurement accuracy of the instrument.
