Description

This high-quality water quality sensor enables the reliable and fast monitoring of important water parameters. With the simultaneous measurement of pH and conductivity, the Ideal water quality sensor is suitable for applications in water treatment, plant cultivation, scientific laboratories, and in municipal and industrial processes.

The water quality sensor has a pH measuring range of 0 ... 14 pH with a high resolution of 0.01 pH and an accuracy of ±0.03 pH. The conductivity measurement is carried out in the range of 0 ... 5000 µS/cm at a resolution of 0.1 µS/cm and an accuracy of ±1.5 % FS. In this way, the sensor provides accurate readings for the continuous monitoring of water quality.

The pH-electrode has a robust plastic shaft with glass diaphragm and is designed for temperatures from 0 to 60 °C. For simple installation, it has a 3/4-inch external thread on the top and bottom. The connection is made via a BNC plug, while the 5 m long connection cable allows a flexible mounting. The conductivity electrode also consists of a durable plastic shaft and is equipped with a 1/2-inch NPT threaded connection.

The 1.26" LCD display allows you to read readings on site. Communication takes place via an RS485 interface, whereby the water quality sensor can be integrated without any problem in the existing measurement, control and automation systems. Installation takes place on a DIN rail in a space-saving way. A supply voltage of 9 to 24 V DC is necessary for operation

With a response time of just 45 seconds, the water quality sensor is particularly suitable for applications requiring fast and reliable measurement results. Typical areas of application are fast control of water quality, plant cultivation, scientific experiments, urban sewage treatment plants, chemical process engineering as well as projects in the field of environmental protection.
