BOQU Alkaline Water Meter Alkaline Water Meter Factory Price
Product Overview
- Model: BOQU PXG-2085Pro Online Nitrate Ion Meter (presented under BOQU alkaline water meter family branding).
- Purpose: continuous online monitoring and control of nitrate ion (NO3-) concentration and temperature in water streams using an ion-selective electrode (ISE).
- Key hardware: molded nitrate PVC membrane ISE, microcomputer-based controller with backlit dot-matrix display, system designed for panel/wall/pipe installation and IP65 protection.
Product Features
- Sensing: advanced ISE technology with a replaceable nitrate PVC membrane; sensor lifetime >1 year (site-dependent).
- Measurement range and performance: wide NO3- range (specs cite ~0.02 ppm to 40,000 ppm / 0–39,000 mg/L), high resolution and staged accuracy (e.g., 0.01, 0.1, 1 ppm resolution tiers).
- Outputs & control: 2× 4–20 mA outputs, RS485 Modbus RTU communication, and 3 relays (high/low control + clean) with programmable delay.
- Data & UI: local data recording (up to 1,000 entries) and history curve display, temperature compensation (Pt1000/NTC10K), English/Traditional Chinese interface.
- Reliability: wide power input (90–260V AC), anti-electromagnetic interference, surge and power-off protection.
Product Value
- Enables continuous, real-time nitrate monitoring for process control and regulatory compliance.
- Lowers operating costs via long-life, replaceable sensor membranes and reduced maintenance downtime.
- Simplifies integration into automation and SCADA systems through standard analog and digital outputs.
- Provides local historical data for troubleshooting, trend analysis and verification without need for external logging.
Product Advantages
- Long sensor life with field-replaceable membrane reduces total cost of ownership.
- Very wide measurement range suitable for diverse water matrices (environmental, industrial, agricultural).
- Multiple outputs and relay controls allow direct control of dosing/cleaning equipment.
- Robust design (IP65, surge/EMI protection, wide power range) for reliable field operation.
- Backed by BOQU design, QC and R&D support—manufacturing experience and product support network.
Application Scenarios
- Environmental monitoring: surface water, groundwater and effluent nitrate surveillance.
- Industrial process water: boiler/feedwater control, cooling towers, wastewater monitoring.
- Agriculture and aquaculture: irrigation water quality, runoff monitoring, pond/tank management.
- Food & beverage: process water quality control where nitrate levels must be tracked.
- Municipal and industrial wastewater treatment: nitrate removal monitoring and automated control (denitrification processes, chemical dosing, cleaning cycles).
