Water conductivity sensor Online Ionic Strength Monitoring for Industrial Water Quality

Water conductivity sensor utilizes a contact-type electrode method and features an RS485 (Modbus-RTU) signal output. It is equipped with signal isolation for enhanced interference resistance, boasts an IP68 waterproof rating, and is suitable for water samples with both high and low ionic strength. It supports online water quality monitoring via immersion in pipelines or tanks.

Water conductivity sensor Designed for environmental water quality monitoring, this device can test water samples with varying ionic strengths—ranging from high to low—meeting the requirements for continuous online conductivity measurement in most industrial and environmental applications. It employs a contact-type electrode for measurements and includes an RS485 interface with a Modbus-RTU communication protocol. Its built-in signal isolation ensures strong resistance to interference, allowing for stable data transmission even in complex field operating conditions.

Water conductivity sensor The device offers excellent measurement reproducibility and thermal stability, with minimal drift. It features a compact design and rapid response time—achieving 98% of the final reading in approximately 30 seconds when placed in still liquid. It measures conductivity across a range of 0–10,000 µS/cm with a resolution of 1 µS/cm, a conductivity accuracy of ±1.5%, and a temperature accuracy of ±0.1°C. An integrated automatic temperature compensation function eliminates deviations caused by water temperature fluctuations, ensuring the reliability of long-term monitoring data. The housing is constructed from ABS and 316L stainless steel, providing an IP68 protection rating that allows for long-term underwater use, while ensuring stable overall performance and an extended service life.

Water conductivity sensor Featuring a 3/4" NPT pipe thread, the device is simple to install; it supports immersion-style installation or can be mounted directly into pipelines or tanks, accommodating a wide range of field installation requirements. It operates on a 12–24 VDC power supply with a power consumption of 0.4 W at 12 V. It comes standard with a 5-meter cable and is designed for an operating temperature range of 0–50°C. The medium must not be frozen, and the operating pressure should be less than 0.2 MPa. Water conductivity sensor is widely used for the online monitoring of water quality in applications such as surface water, sewage, and industrial circulating water, simultaneously collecting data on both electrical conductivity and water temperature. Its compact structural design minimizes space requirements for on-site installation, while its stable hardware performance reduces the frequency of maintenance—making it well-suited for various long-term, continuous online water quality monitoring projects.
