Digital Water Hardness Meter - for Apartment - BOQU

Product Overview

1) Product overview

Product Features

- The BOQU PXG-2085Pro is an online potassium-ion (K+) analyzer/controller that uses an ion-selective electrode (ISE) with a molded potassium PVC membrane for continuous in-line monitoring.

Product Value

- It is a microcomputer-based instrument with a user-friendly interface, local data recording and flexible installation (panel/wall/pipe).

Product Advantages

- Designed for continuous process monitoring and control in water applications, the potassium sensor membrane is replaceable and the electrode life exceeds one year under typical conditions.

Application Scenarios

2) Product features

- Measurement: potassium ion (K+) range up to 0–39,000 mg/L (0.02 ppm minimum reported), with selectable resolutions (0.01 / 0.1 / 1) and stated accuracies (±0.01 / ±0.1 / ±1 ppm depending on range).

- Temperature measurement and compensation (Pt1000 / NTC10K), temp. range ?10 to +130 °C, ambient operating 0 to +70 °C.

- Outputs & communication: 2 × 4–20 mA outputs (max 500 Ω), RS485 Modbus RTU, and 3 relays (High/Low control and Clean) with adjustable delay.

- Data logging: local storage for 1,000 records and historical data curve display; back-lit dot-matrix display; language options (English / Traditional Chinese).

- Ruggedness & power: IP65 enclosure, anti-interference and surge protection, power-off protection, wide power supply 90–260 V AC 50/60 Hz.

3) Product value

- Enables continuous real-time potassium monitoring to support process control, regulatory compliance and early detection of water quality shifts.

- Lowers operating costs through a durable, replaceable ISE membrane that minimizes sensor replacement frequency and maintenance expense.

- Integrates easily into automation systems (4–20 mA, relays, Modbus) to trigger control actions or alarms and to record event history for traceability and troubleshooting.

- Robust construction and protective features reduce downtime and data loss risk in field and industrial environments.

4) Product advantages

- Very wide measurement range and fine resolution for both low-level and high-concentration potassium monitoring.

- Long electrode lifetime (>1 year) with user-replaceable membrane for economical upkeep.

- Multiple outputs and relay controls plus standard Modbus allow flexible integration with PLCs, DCS or building management systems.

- Built for reliability: IP65 protection, anti-electromagnetic interference, surge and power-off protection.

- Universal power input and multiple installation options (panel/wall/pipe) simplify deployment worldwide.

5) Application scenarios

- Environmental monitoring and wastewater effluent control.

- Industrial process water monitoring and process control.

- Agriculture and farming applications (irrigation systems, nutrient monitoring, hydroponics).

- Food and beverage process control and quality assurance.

- Building or apartment water systems and any site needing continuous potassium monitoring and automated control.
