NS-CD301 Conductivity TDS Digital Sensor Introduction: The conductivity/TDS digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company. Using high-performance CPU chips to measure TDS and temperature. Data viewing, debugging, and maintenance can be carried out through mobile apps or computers. It has the characteristics of easy maintenance, high stability, excellent repeatability, and versatility, and can accurately measure the conductivity/TDS value in solutions. Widely used for continuous monitoring of conductivity/TDS in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. Features: 1. This product is a conductivity/TDS digital sensor that can directly output RS485 signals and 4-20mA signals 2. The product has high precision, high stability, and strong anti-interference ability 3. Without the need for instruments, it can be directly connected to devices with RS485/4-20mA signal interfaces such as computers and PLCs for data collection and maintenance; Convenient for users to integrate sensors into industrial control environments such as upper computer systems and IoT. 4. Use a mobile app to collect, debug, and maintain data from sensors through wired (OTG cable and 485 to USB module) or wireless networks (such as WIFI, GPRS, and other wireless networks). 5. The sensor can be set through RS485 communication, including slave address and Baud, online calibration, factory restoration, 4-20mA output corresponding range, proportional coefficient and incremental compensation. Without the need for instruments, it can be directly connected to devices with RS485/4-20mA signal interfaces such as computers and PLCs for data collection. Convenient for users to integrate sensors into industrial control environments such as upper computer systems and IoT systems. 6. The probe can be replaced. 7. Use the three-point correction method.
