Industrial wastewater and sewage testing is mainly a general term for the monitoring of wastewater, sewage and aquatic organisms discharged by enterprises and factories during the production process. According to the products and processing objects of industrial enterprises, industrial wastewater can be divided into papermaking wastewater, etching wastewater, textile wastewater, tanning wastewater, pesticide wastewater, metallurgical wastewater, printing and dyeing wastewater, oil refining wastewater, medical wastewater, etc. The monitoring parameters of industrial wastewater usually include: conductivity, pH value, color, turbidity, suspended solids, dissolved oxygen, ammonia nitrogen, total phosphorus, total nitrogen and various ions. The pH value is an important parameter in wastewater treatment. For the neutralization treatment of acid and alkali wastewater, the pH value is the most critical indicator to control the dosage and judge whether the wastewater treatment meets the standards. This requires the monitoring of the pH value to be timely and precise.
The high-end series meter APX2-C3 developed and produced by Daruifuno has multiple functions, high precision and stable display, and can be connected to various analog pH electrodes. For wastewater treatment such as acid-base neutralization, the treatment process has complex requirements and strong dependence on pH value. It is necessary to control the dosage according to the measured pH value, and even needs to automatically adjust and control the dosage of chemicals. APX2-C3 is equipped with two The settable SPST relay can automatically control dosing.
