Nobo - Model NS-CD001 - Conductivity / TDS Digital Sensor
Digital conductivity sensor is a new generation of intelligent water quality detection digtial sensor independently developed by our company. Using high-performance CUP chip to complete conductivity measurement, data can be viewed, debugged and maintained by mobile phones and computers. It has the characteristics of easy maintenance, high stability, excellent repeatability and multi-function, and can accurately measure conductivity value in solution. It is widely used in continuous monitoring of conductivity value in solutions, such as thermal power, chemical fertilizer, metallurgy, environmental protection, parmaceutical, biochemial, food and tap water.
- This product is conductivity digial sensor, which can directly output RS485/4-20mA signal.
- High precision, high stability and preferable antijamming ability.
- No need instrument, can directly connect to computers, PLC and other devices with RS485 signal interface for data acquisition and maintenance. It’s convenient for users to integrate data measured by sensors into the industrial control environment, such as host computer system and IOT.
- Using mobile phone APP, to collect, debug and maintain of the data through wired(OTG, and 485 transfer USB module) or wireless network(for example: WIFI, GPRS).
- The sensor can be set up by RE485 communication, such as slave address and Baud rate, online calibration, factory recovery, 4-20mA output corresponding range (can optional), proportional coefficient, incremental compensation and so on.
- Using three point correction method.
- Power off protects > 10 years.
