Note: the supplied specification describes the BOQU PXG-2085Pro Online Nitrite (NO2-) Ion Meter. If you intended a nitrate (NO3-) meter, please confirm — the summary below follows the provided nitrite-product details.
Product Features
1) Product overview
Product Value
- Model: BOQU PXG-2085Pro Online Nitrite Ion Meter (ion-selective electrode, ISE).
Product Advantages
- Purpose: continuous online monitoring and control of nitrite (NO2-) concentration and temperature in water streams.
Application Scenarios
- Form: microcomputer-based controller with external ISE probe; panel/wall/pipe installation; IP65 enclosure.
2) Product features
- Measurement range: broad span up to ~0.02–1000 ppm (wide-range nitrite detection).
- Resolution & accuracy: resolutions 0.01/0.1/1 depending on range; accuracies ±0.01/±0.1/±1 ppm by range; temperature measurement with Pt1000/NTC10K compensation and 0.2°C accuracy.
- Outputs & controls: 2 × 4–20 mA outputs (max 500 Ω), RS485 Modbus RTU communication, and 3 relays (high/low control and clean) with 0–120 s delay.
- Data & interface: local data recording (1,000 records) with history curve display, backlit dot-matrix display, English/traditional Chinese language option.
- Robust design: replaceable molded PVC nitrite membrane ISE (sensor life >1 year typical), anti-electromagnetic interference, surge protection, power-off data protection, and wide AC input (90–260 VAC).
3) Product value
- Continuous automated monitoring enables real-time process control and rapid response to nitrite excursions.
- Replaceable sensor membrane and long electrode life lower maintenance and operating costs.
- Multi-output communications and relay control facilitate integration with PLCs/SCADA and automated dosing/cleaning systems.
- Local data logging and history curves support compliance reporting, troubleshooting and trend analysis.
- Wide power range and IP65 rating allow flexible deployment across global sites and harsh field conditions.
4) Product advantages (key differentiators)
- ISE-based measurement for direct, continuous ion-specific detection (suitable for online effluent and process streams).
- Very wide measurement range (trace to high concentrations) in a single instrument.
- Durable, field-replaceable sensor membrane designed by BOQU to extend service life and reduce downtime.
- Multiple outputs (analog, digital, relays) plus local data storage for versatile control and integration.
- Built-in protections (EMI, surge, power-off) and sturdy enclosure improve reliability in industrial environments.
5) Application scenarios
- Environmental monitoring: wastewater effluent, river/stream monitoring, regulatory compliance checks.
- Industrial water: process water control, cooling water treatment, chemical plants.
- Agriculture & aquaculture: irrigation runoff monitoring, pond/tank water quality control.
- Food & beverage: process effluent monitoring and production line water quality control.
- Any continuous online nitrite-monitoring need where automated control, data logging, and integration with control systems are required.
