OK-ZSJ2 Benchtop Comprehensive Water Quality Analyzer
Product Introduction
The OK-ZSJ2 Benchtop Comprehensive Water Quality Analyzer is a compact multi-parameter water testing instrument designed for both field water quality testing and laboratory water analysis.
The instrument uses pre-programmed standard testing methods and stores corresponding calibration curves in the analyzer. When used with compatible reagents, the prepared sample can be placed directly into the instrument for quantitative analysis, with the measurement result displayed automatically.
With multiple water quality parameters, six-channel simultaneous testing, automatic wavelength selection, built-in printing, USB data transfer, GPRS data upload and GPS positioning, the OK-ZSJ2 provides an integrated solution for routine water quality monitoring.

Performance Features
• Multi-parameter water testing: Supports more than 30 water quality parameters, including turbidity, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, residual chlorine, COD and pH.
• Pre-programmed testing methods: Standard testing procedures and calibration curves are pre-programmed into the instrument.
•  Three result modes: Results can be displayed as concentration, absorbance or transmittance.
• Automatic wavelength selection: Automatically selects the appropriate wavelength within the programmed parameter range.
• 6-channel testing: Uses standard cuvettes and supports simultaneous detection through six channels.
• Compact portable design: Suitable for both laboratory and on-site water quality testing.
• Backlit LCD: 128 × 64 dot-matrix LCD provides clear measurement information.
•  Chinese interface: Full Chinese display and simple operation.
• High-stability optics: Imported photoelectric converter and ultra-high-brightness LED light source improve measurement stability.
•  Built-in printer: Allows real-time printing of water quality test results.
•  Rechargeable lithium battery: Supports field testing where external charging facilities are unavailable.
•  USB data output: Convenient connection to a computer for data transfer.
•  GPRS data upload: Test data can be uploaded to a designated platform.
• GPS positioning: Supports location information for field inspection and monitoring.
•  Rugged insulation design: The robust structure is designed for demanding field environments.

Working Principle
The OK-ZSJ2 uses photometric analysis for its programmed water quality testing methods. After the water sample reacts with the corresponding reagent, the optical characteristics of the prepared sample are measured through the instrument's optical system.
Depending on the programmed test item, the instrument can display the result as concentration, absorbance or transmittance. Standard calibration curves are pre-programmed into the system, allowing quantitative analysis when compatible reagents and prescribed testing procedures are used.
The instrument automatically selects the appropriate wavelength from its programmed wavelength range. The optical system uses ultra-high-brightness LEDs as light sources and photoelectric converters as detectors.
