Professional Online Water Hardness Meter for Irrigation

Product Overview

1) Product overview

Product Features

- Model: BH-485-ION — a professional online digital ion sensor designed for continuous water hardness and ion monitoring (including Ca2+ for hardness, plus F-, Cl-, NO3-, NH4+, K+, etc.).

Product Value

- Digital RS485 output with standard Modbus RTU for direct integration into controllers, PLCs and SCADA systems.

Product Advantages

- Rugged IP68 corrosion‑resistant housing (PPS+POM) and industrial composite electrodes with double salt‑bridge reference for long life.

Application Scenarios

2) Product features

- Measurement range 0.02–1000 ppm (mg/L) with 0.01 mg/L resolution; accuracy ±2% (0–100 mg/L) and ±5% (0–1000 mg/L) at 25°C.

- Built‑in PT1000 temperature sensor and automatic temperature compensation; response time

- Digital RS485 (Modbus RTU) output, customizable power (standard 12 V; options 5 V / 24 V), and extendable cable length.

- Multiple removable membranes available for different ions; replaceable membrane design for extended service life.

- Compact probe (≈Ø30 × 250 mm), suitable for sinking or inline/flow tank installation; waterproof cable and IP68 rating.

3) Product value

- Real‑time, reliable hardness and ion concentration data to prevent scale formation, optimize irrigation/fertigation dosing, and protect pumps and emitters.

- Enables remote monitoring and automated control via Modbus, improving operational efficiency and reducing manual sampling and lab costs.

- Low maintenance and long working life reduce downtime and lifecycle costs for irrigation systems and water treatment equipment.

4) Product advantages

- High accuracy and fast response for timely decision making in irrigation management.

- Robust materials and IP68 protection allow use in harsh water conditions and continuous online operation.

- Flexible configuration (ion-specific membranes, customizable power and cable lengths) for diverse system requirements.

- Digital output simplifies integration with existing automation and data-logging platforms.

- Replaceable membrane and industrial electrode design extend usable life and lower operating costs.

5) Application scenarios

- Irrigation systems: monitoring water hardness (Ca2+) and other ions in drip, sprinkler and pivot irrigation to avoid clogging and scaling.

- Fertigation and greenhouse nutrient control: real‑time ion monitoring for precise fertilizer dosing.

- Agricultural water quality management: surface water, wells and supply lines used for crops.

- On‑site wastewater, runoff and drainage monitoring related to farms and agri‑industrial facilities.

- Integration into water treatment, recirculation tanks or flow channels where continuous ion measurement is required.
