NS-LZ101 Digital Water Hardness Ion Sensor

Product Introduction
The NS-LZ101 Digital Water Hardness Ion Sensor uses an advanced imported ion-selective electrode (ISE) method for continuous monitoring of water hardness. It provides high sensitivity, rapid signal response, accurate measurement, stable performance, and simplified maintenance.
The sensor directly outputs an RS485 digital signal, allowing connection to computers, PLCs, and industrial control systems without a separate measuring instrument. Through compatible mobile applications or computer systems, users can perform data acquisition, parameter configuration, calibration, and maintenance.
With automatic temperature compensation, a replaceable probe, two-point calibration, and IP68 protection, the NS-LZ101 is designed for continuous water hardness monitoring and control in drinking water treatment plants, bottled water plants, drinking water distribution networks, and water treatment engineering.

Performance Features
• Advanced ISE measurement: Uses an ion-selective electrode method for water hardness measurement.
• High measurement performance: High sensitivity, fast response, and stable measurement performance.
• RS485 digital output: Directly outputs digital data through the RS485 interface.
• Automatic temperature compensation: Compensates for temperature effects during measurement.
• Direct system integration: Can connect directly to computers, PLCs, and compatible industrial control systems without a separate meter.
• Mobile app support: Supports data acquisition, configuration, calibration, and maintenance through compatible wired or wireless connections.
• Flexible parameter configuration: RS485 communication supports slave address, baud rate, online calibration, factory reset, measurement range, proportional coefficient, and incremental compensation settings.
• Replaceable probe: The sensing probe can be replaced for convenient maintenance.
• Two-point calibration: Supports two-point correction for measurement calibration.
• IP68 protection: Suitable for continuous water quality monitoring environments.

Working Principle
The NS-LZ101 uses the ion-selective electrode (ISE) method to detect ions associated with water hardness. The ion-selective sensing element generates an electrical potential related to the concentration of the target ions in the water.
The sensor measures and processes this electrical signal and converts it into a corresponding water hardness value. Automatic temperature compensation is used to compensate for the influence of temperature changes on the measurement.
The processed data is transmitted through the RS485 interface, allowing the sensor to communicate with computers, PLCs, and compatible industrial or IoT monitoring systems.
