0-100mg/L OEM Range Total Nickel Online Water Quality Analyzer with Dimethylglyoxime Spectrophotometric Method and RS-232 4-20mA RS-485 Output

This method is applicable to wastewater with nickel concentrations within the range of 0–100 mg/L.

Unique Design: This product features a distinctive design that ensures lower failure rates, reduced maintenance requirements, minimal reagent consumption, and higher cost-effectiveness compared to similar products.

• Enables flexible reagent sampling timing and diverse channel configurations.
• Minimizes dead volume for easy maintenance and extended service life.

• Utilizes a visual photoelectric system for precise reagent measurement, eliminating quantitative errors caused by peristaltic pump tube wear.
• Achieves accurate micro-dosing with 0.7 mL per dose, significantly reducing reagent usage.

• Employs a peristaltic pump with negative pressure suction, creating an air buffer zone between reagents and the pump tube to prevent corrosion.
• Simplifies and enhances flexibility in reagent mixing.

• Operates under high-temperature and high-pressure conditions to accelerate reactions.
• Eliminates corrosion risks from volatile gases in open systems.

• Uses imported modified PTFE (polytetrafluoroethylene) transparent tubing with an inner diameter > 1.5 mm to minimize clogging by particulate matter in water samples.

The water sample is digested with acid, then mixed with a conditioning agent and oxidized with an oxidizing agent. Under alkaline conditions and in the presence of an indicator, nickel ions react with the indicator to form a colored complex. The analyzer detects this color change, converts the variation into a total nickel concentration value, and outputs the result. The amount of colored complex formed corresponds to the total nickel content in the sample.
