Digital Water Hardness Meter - for Swimming Pool - BOQU

Product Overview

- BOQU Digital Water Hardness Meter (part of the BOQU online ion analyzer family, e.g. PFG-3085 series) is an industrial micro-computer based online ion analyzer designed to measure water hardness and multiple ions (F-, Cl-, K+, NO3-, NH4+, Ca2+, Mg2+ and others) using appropriate ion-selective probes.

- Designed for continuous monitoring with a user-friendly interface, long working life and flexible panel/wall/pipe installation for permanent pool and process monitoring.

Product Features

- Multi-ion capability (hardness plus fluoride, chloride, nitrate, ammonium, potassium, calcium, magnesium, etc.) and automatic unit switching depending on the sensor.

- Measurement specifics (example fluoride specification): 0.00–5000 ppm range, resolutions 0.01/0.1/1, high accuracy options. mV input range 0.00–1000.00 mV; input impedance >10^12 Ω.

- Temperature compensation (Pt100/NTC10K), wide temp range (-10 to +130 °C), temp resolution 0.1 °C, temp accuracy 0.2 °C.

- Outputs and communications: isolated 4–20 mA (ion and temperature), RS485 (Modbus RTU), up to three multifunction relays (clean/period/alarm/error) rated 5 A.

- Large data logger (up to 500,000 records), backlit dot-matrix display, 3-language UI, cleaning timing control, IP65 protection, low power consumption (90–260 VAC,

Product Value

- Enables continuous, precise hardness and ion monitoring to protect pool equipment, prevent scaling, and maintain swimmer comfort and safety.

- Data logging, alarm relays and standard outputs support regulatory compliance, trend analysis and remote integration into building or plant control systems.

- Robust design and long service life reduce maintenance costs and downtime for pools, facilities and industrial processes.

Product Advantages

- Versatile multi-ion support lets one instrument serve multiple monitoring needs by changing electrodes rather than buying separate analyzers.

- High sensitivity, wide measuring range and strong accuracy give reliable, actionable readings for both low-ppm and high-ppm conditions.

- Industrial-grade hardware: isolated outputs, Modbus communications, IP65 enclosure, powerful relays and large onboard memory.

- Flexible installation options (panel/wall/pipe) and multilingual user interface simplify deployment and operation across sites.

Application Scenarios

- Swimming pools and aquatics centers — continuous hardness and ion control to prevent scaling, control water quality and ensure user comfort.

- Drinking water treatment and distribution monitoring for compliance and process control.

- Power plants, industrial wastewater, electroplating and environmental monitoring where ion concentration and hardness must be tracked.

- Hotels, spas, municipal facilities and any building management systems requiring integrated online water quality monitoring.
