Online Ion Meter Digital Water Hardness Tester Supply
Product Overview
1) Product overview
Product Features
- The Online Ion Meter / Digital Water Hardness Tester (model PFG-3085) is a micro-computer based industrial online ion analyzer for continuous monitoring of water ions and hardness. It supports multiple ion types (F-, Cl-, Mg2+, Ca2+, NO3-, NH4+), provides automatic unit switching for different sensors, and is designed for panel, wall or pipe installation with IP65 protection.

Product Advantages
- Measuring range 0.00–5000 ppm with tiered resolution (0.01, 0.1, 1) and high accuracy (±0.01/±0.1/±1 ppm depending on range).
Application Scenarios
- mV input 0–1000.00 mV; temperature measurement and compensation (Pt1000 / NTC10K), temp range ?10 to +130 °C.
- Outputs: isolated 4–20 mA for ion and temperature (max load 500 Ω), RS485 Modbus RTU, and up to three relays (5 A @250 VAC/30 VDC).
- Built-in data logger (up to 500,000 records), multilingual UI (English / simplified & traditional Chinese), backlit dot-matrix display, low power consumption (
3) Product value
- Enables reliable, continuous online monitoring and historical data logging for process control, compliance and troubleshooting.
- Accurate multi-ion measurement (including Ca2+ and Mg2+ for hardness) supports automated control, reduces manual testing, and improves water treatment efficiency and safety.
4) Product advantages
- Multi-ion capability and automatic unit switching for versatile deployment.
- High accuracy and wide dynamic range for both trace and bulk concentrations.
- Industrial I/O (isolated current outputs, RS485, relays) for easy integration into control systems.
- Robust build (IP65), flexible mounting, long service life and large onboard data storage.
5) Application scenarios
- Power plants, drinking water treatment and distribution, industrial wastewater monitoring, wastewater treatment plants, environmental monitoring, electroplating and other industrial processes requiring continuous ion or hardness measurement.
