BOQU Optical Do Meter Optical Do Meter Manufacturing
Product Overview
1) Product overview
Product Features
- BOQU Pro1603OXY optical dissolved oxygen (DO) meter manufactured by Shanghai Boqu Instrument Co., Ltd.
Product Value
- Based on German technology and designed to international standards for industrial dissolved oxygen measurement.
Product Advantages
- Measures dissolved oxygen (0.00–20.0 mg/L or 0.0–300%) and temperature (–10.0 to +130.0°C) with two-point calibration and 4–20 mA output.
Application Scenarios
- Robust construction with IP65 protection and operation from 20–253 V AC/DC.
2) Product features
- Optical DO sensing with simultaneous display of dissolved oxygen and temperature on a large LCD.
- VariPower? wide-range power supply chip supporting 20–253 V AC/DC and large supply voltage fluctuations.
- Two-point calibration, NTC temperature compensation (22K / 30K), and 4.00–20.00 mA output (±0.1 mA).
- Rugged PBT housing, rigid metal conduit, and waterproof design (IP65).
3) Product value
- Provides accurate, continuous monitoring of dissolved oxygen and temperature for process control and safety.
- Wide input-voltage tolerance and durable build reduce downtime and installation constraints.
- Long warranty and claimed very high reliability lower lifetime operating and maintenance costs.
- Standard 4–20 mA output enables straightforward integration with control systems and data acquisition.
4) Product advantages
- Technology origin: German design and circuit technology not commonly used by competitors.
- Extended warranty: 3-year manufacturer warranty.
- Exceptional power flexibility: works across 20–253 V AC/DC without performance loss.
- Low energy consumption and simplified electronics for reliability; manufacturer cites an extremely long MTBF (stated as 110 years).
- Industrial-grade protection and materials for harsh environments.
5) Application scenarios
- Fermentation tanks, biotechnology and pharmaceutical processes.
- Food and beverage production and quality control.
- Chemical production, paper and starch pulp processing, petroleum smelting.
- Cooling water, boiler water, ion exchanger regeneration, and general industrial wastewater or process monitoring.
