Product Specification

Online Water Quality Nitrite Monitor

Product Introduction:

The online nitrite ion sensor is an intelligent sensing device designed specifically for water quality monitoring scenarios. It uses PVC membrane ion selective electrode method to quickly and accurately measure the concentration of nitrite in water. The device is equipped with an automatic temperature compensation function, which effectively reduces the impact of environmental temperature changes on measurement results and ensures stable and reliable data. The whole machine adopts 316L stainless steel shell with a protection level of IP68. It can be immersed in pipelines, water tanks or natural water bodies for a long time and is suitable for complex working conditions of 0-40 ℃ and ≤ 0.2MPa. The product has undergone 72 hours of aging and calibration before leaving the factory, and is ready to use immediately, meeting the online monitoring needs of environmental protection, aquaculture, industrial circulating water, drinking water pipe networks, and other fields.

Core Features:

• High precision measurement: range 0~2.000 mg/L, resolution 0.001 mg/L, accuracy ± 5%, meeting the requirements for monitoring trace changes in nitrite.
• Stable and durable: patented reference system (salt bridge micro pressure structure) extends electrode life; The shell material is 316L, which has strong corrosion resistance.
• Flexible output: Standard RS-485 (Modbus RTU) interface, optional 4-20mA current output, convenient for connecting to third-party devices such as PLC, DCS, touch screen, etc.
• Easy installation: 3/4 NPT thread, supports immersion installation (tilt ≥ 15 °), comes standard with 5-meter waterproof cable, easy to deploy on site.
• Low power design: Powered by 12-24VDC, with a power consumption of only 0.2W, it can operate continuously for a long time.
