BOQU Online Water Hardness Meter Manufacturing

Product Overview

Note: the supplied details describe the BOQU PXG-2085Pro Online Ammonium Ion Meter (ammonium/NH4+), so the summary below is based on that instrument.

Product Features

1) Product overview

Product Value

- BOQU PXG-2085Pro is an online, microcomputer-based ammonium (NH4+) ion meter using an ion-selective electrode (ISE) for continuous, real-time monitoring. It is built from durable, industry-grade materials, offers a user-friendly interface and local data recording, and is designed for panel/wall/pipe installation.

Application Scenarios

- Measurement principle: molded PVC ammonium ISE with >1 year electrode life (replaceable membrane).

- Measurement range: approximately 0.02 ppm to 18,000 ppm NH4+ with resolutions of 0.01 (for

- Accuracy tiers: ±0.01 ppm, ±0.1 ppm, ±1 ppm (corresponding to ranges).

- Temperature compensation: Pt1000 / NTC10K; temperature range -10 to +130 °C; ambient 0 to +70 °C.

- Outputs & control: 2 × 4–20 mA outputs (max load 500 Ω), RS485 Modbus RTU, and 3 relays (high/low control and clean) with adjustable relay delay (0–120 s).

- Data & protection: local data recording for 1,000 records, backlit dot-matrix display, English/Traditional Chinese, IP65 protection, anti-electromagnetic interference, surge and power-off protection.

- Power: wide input 90–260 V AC, 50/60 Hz.

3) Product value

- Low total cost of ownership through long electrode life and replaceable sensor membrane (reduced maintenance and spare costs).

- Reliable, continuous monitoring enables better process control, regulatory compliance and faster response to concentration excursions.

- Local data logging and multiple outputs facilitate on-site control and integration with SCADA/DCS for automated operations.

- Robust design and wide power compatibility support use across many regions and industrial sites.

4) Product advantages

- Very wide measurement range suitable for trace to very high NH4+ concentrations.

- High input impedance and ISE technology deliver stable, selective ammonium readings.

- Flexible interfacing: analog outputs, relays and Modbus for easy system integration and automation.

- Durable, field-serviceable sensor membrane minimizes downtime and lowers maintenance burden.

- Built-in protections (EMI, surge, power-off) and IP65 casing improve reliability in industrial environments.

5) Application scenarios

- Wastewater treatment plant monitoring and process control (influent/effluent and nitrification/denitrification control).

- Environmental water and surface water quality monitoring for ammonium contamination.

- Industrial process water monitoring where ammonium is relevant (chemical, textile, pulp & paper, etc.).

- Food & beverage and aquaculture facilities where ammonium levels affect product quality or biological systems.

- Any automated control loop or regulatory compliance application requiring continuous online ammonium measurement.
