Product Overview
Note: the supplied description includes both TCuG-3050 (total copper) in the title and detailed specs for TNiG-3051 (online total nickel analyzer). The working principle and method (dimethylglyoxime spectrophotometry) match a total-nickel analyzer. The summary below follows the detailed analyzer information provided.
Product Features
1) Product overview
Product Value
- Online automatic total-nickel analyzer (model TNiG-3051) from Shanghai BOQU Instrument Co., Ltd., designed to perform continuous, automatic determination of total nickel in water using an optical/colorimetric method that complies with national environmental protection standards.
Product Advantages
- Intended for real-time monitoring of nickel in surface water, industrial process water and industrial wastewater.
Application Scenarios
2) Product features
- Working principle: sample oxidation (ammonium persulfate) and color development with dimethylglyoxime in alkaline conditions; color change is measured optically and converted to total-nickel concentration.
- Measuring ranges: 0.00–2.00 mg/L and 0.10–10.00 mg/L (range selection as required).
- Accuracy and precision: ≤±10% (≥0.2 mg/L) or ≤±0.02 mg/L (
- Adjustable digestion/measurement time (5–120 min), minimum measurement cycle ~50 minutes; flexible sampling interval (55–9999 min) and calibration interval (1–99 days).
- Outputs and interface: 4–20 mA (2 channels), RS232/RS485, touch-screen display with command input; automatic discharge of residual reagents after resets and power cycles; data saved on alarms and power loss.
- Operational features: monthly routine maintenance (~30 minutes), indoor use recommended (5–28 °C, ≤90% humidity), AC220V power.
3) Product value
- Enables continuous, automated monitoring of nickel to ensure regulatory compliance and timely detection of contamination events.
- Reduces reliance on manual grab sampling and off-site lab analysis, saving time and operating costs while providing near real-time process control data.
- Supports environmental protection and industrial wastewater management by delivering actionable measurements for pollution prevention and treatment optimization.
4) Product advantages
- Method aligns with environmental protection standards and uses a well-established colorimetric reagent (dimethylglyoxime) for nickel specificity.
- Good analytical performance: solid accuracy, repeatability and short-term stability for reliable online data.
- High automation and remote/output capabilities (4–20 mA, digital ports) facilitate integration with control systems and SCADA.
- Built-in safety and convenience: automatic flushing after abnormal events, data retention on failures, touch-screen control.
- Backed by BOQU’s manufacturing and quality-management systems—modern production base, strict quality control and established supplier reputation.
5) Application scenarios
- Continuous monitoring of nickel in: surface waters (rivers, lakes), industrial process waters, effluents from electroplating, metal finishing, mining and metallurgical operations, chemical plants, power plants and municipal/industrial wastewater treatment plants.
- Environmental compliance monitoring, pollution prevention programs, process control for treatment systems, and any situation requiring online total-nickel surveillance.
