Chlorine meter digital NS-CL128 free chlorine sensors in pool
Product Introduction： Digital residual chlorine sensor is a new generation of intelligent water quality monitoring sensor which is researched and developed by our company.Using advanced non-membrane constant voltage sensor no need to change the membrane and medicament. Stable performance, easy maintenance, support to check the data, debugging and maintenance by mobile APP or computer. With many features, such as, high sensitive, quick response , exact measurement, high stability, excellent repeatability, easy maintenance and multi -functions and so on. It can measure the residual chlorine in liquid exactly. It is widely used to online monitor and control the residual chlorine content in liquid. Such as, circulating water, swimming pool, drinking water plant, hospital waste water , water quality treatment project ect.
Chlorine meter digital NS-CL128 Digital free chlorine sensor in water
Main Feature ：
Digital residual chlorine sensor, output RS485 signal and 4~20mA signal.
High accuracy, high stability , strong anti-jamming
It can connect to computer, PLC and other equipment which has Rs485and 4-20mA signal interface to collect data and maintenance without instrument. It is convenient for users to integrate sensors into industrial control environment, such as, upper computer system and the internet of things .
By using the mobile phone app, the sensor can be collected, debugged and maintained by the wireless network (such as wifig / GPRS) or wired network ( OTG line and 485 / usb module)
The sensor can be set with RS485 communication for its slave address, baud rate,online calibration, recoverable factory setting, 4-20ma output range,coefficient of proportionality, incremental compensation and other settings.
Using two-point calibration method
Power off protection＞10 years
The key components are imported from foreign brand .
