For Paper Textiles Iron Analyzer by BOQU
Product Overview
Note: the detailed text you provided describes the BOQU GeG-3052 online hexavalent chromium analyzer. Below are five concise summary points based on that introduction.
Product Features
1) Product overview
Product Value
- Model: BOQU GeG-3052 — an online, automatic hexavalent chromium (Cr(VI)) analyzer built to national environmental protection standards.
Product Advantages
- Method: diphenylcarbazide spectrophotometry (colorimetric detection).
Application Scenarios
- Purpose: continuous, automatic monitoring and quantification of hexavalent chromium in water.
2) Key product features
- Measurement ranges: 0.00–2.00 mg/L and 0.10–10.00 mg/L (selectable).
- Accuracy/precision: ≤±10% (≥0.2 mg/L) or ≤±0.02 mg/L (
- Automated sample digestion (sealed high‑temperature/high‑pressure digestion) with adjustable digestion time (5–120 min) and minimum measurement period ≈50 minutes.
- Low reagent consumption and accurate reagent dosing via photoelectric metering and a selectable valve assembly; peristaltic pump configured for negative‑pressure suction with an air buffer to reduce tubing corrosion.
- Outputs and interface: 4–20 mA (2 channels), RS232/RS485, touch‑screen display; data saved on alarms and power loss. Automatic purge/resume after reset or power restoration.
3) Product value
- Enables continuous, real‑time monitoring of Cr(VI) for regulatory compliance and process control, reducing manual sampling and lab turnaround.
- Reliable, trace‑level detection with stable automated operation minimizes downtime and operator intervention.
- Lower reagent usage and automated maintenance features reduce ongoing operating costs.
- Robust data logging and communication outputs support integration with process control or environmental monitoring systems.
4) Product advantages (compared with similar analyzers)
- Lower failure rate and maintenance need due to unique design and improved component choices.
- More accurate reagent dosing than conventional peristaltic‑only systems (photoelectric metering avoids quantitative drift from tube wear).
- Corrosion and clogging reduction: PTFE transparent reagent tubing (≥1.5 mm ID) and negative‑pressure pumping with an air buffer.
- Accelerated and contained reaction via sealed digestion, avoiding volatilization and corrosive gas problems in open systems.
- Backed by BOQU’s production capabilities and customer service (pre‑/after‑sales support; domestic and export experience).
5) Application scenarios
- Online monitoring of surface water (rivers, lakes) for environmental protection.
- Industrial process water control where Cr(VI) must be monitored (metal finishing, plating, tanning, chemical manufacturing).
- Industrial wastewater monitoring and discharge compliance checks.
- Integration into plant process control, environmental monitoring networks, or automated compliance reporting systems.
