Product Overview

GeG-3052 is an online, automatic hexavalent chromium analyzer (diphenylcarbazide spectrophotometry) designed to meet national environmental protection standards. It provides continuous, automatic measurement and data logging for hexavalent chromium concentrations with sturdy export packaging and quality-controlled production from BOQU Instrument.

Product Features

- Optical diphenylcarbazide colorimetric detection; measuring ranges 0.00–2.00 mg/L and 0.10–10.00 mg/L.

- Accuracy: ≤±10% (≥0.2 mg/L) and ≤±0.02 mg/L (

- Minimum measurement cycle ~50 minutes; digestion time adjustable 5–120 min; sampling interval and calibration period adjustable.

- Outputs: 4–20 mA (two channels), RS232/RS485; touch-screen operation; data preserved through alarms and power loss.

- Automatic reactant purge and resume after resets; recommended indoor operation +5–28°C, ≤90% RH.

Product Value

The analyzer enables reliable, continuous online monitoring of hexavalent chromium to support regulatory compliance, rapid process control and environmental protection. Its automatic operation, data retention, and standard outputs simplify integration into plant control systems and reduce manual sampling and lab costs.

Product Advantages

- Low reagent consumption and lower failure/maintenance rates versus similar instruments thanks to a carefully engineered fluid and reagent system.

- Precise reagent dosing via visible photoelectric metering (avoids peristaltic tube wear errors) and negative?pressure peristaltic suction with an air buffer to protect tubing.

- Sealed high?temperature/high?pressure digestion speeds reaction, reduces volatilization/corrosion issues, and improves measurement reliability.

- Durable PTFE reagent tubing and modular valve/injection design for consistent long?term operation. BOQU also offers trained customer service and export experience.

Application Scenarios

Online monitoring of hexavalent chromium and other heavy metals in surface waters, industrial process water and industrial wastewater; use in municipal and industrial effluent treatment plants, environmental monitoring stations, and industrial process control systems where continuous, regulatory?grade chromium measurement is required.
