Online Conductivity Indicator/Controller – Arka

Our Online TDS/Conductivity Meter is a robust and high-accuracy instrument designed to monitor TDS and conductivity levels in real time. Whether it's for boiler feed water, cooling towers, RO systems, wastewater treatment, or process applications, this meter delivers accurate data to help you control water chemistry and reduce operating costs.

The device features continuous measurement, temperature compensation, and analog/digital outputs, allowing seamless integration into existing SCADA, PLC, or automation systems. With a user-friendly interface, durable construction, and low maintenance, it is ideal for industrial applications where reliability and accuracy are non-negotiable.

Key Features

• Measurement : Measures and displays Total Dissolved Solids (ppm) or Conductivity (µS/cm or mS/cm) with high accuracy.
• Temperature Compensation  : Ensures consistent readings across varying process temperatures, improving measurement reliability.
• Wide Measuring Range : Conductivity: 0–20 µS/cm to 0–200 mS/cm
• TDS: 0–10 ppm to 0–100,000 ppm (depending on cell constant & configuration)
• Selectable Cell Constants (K=0.1 / 1.0 / 10.0) : Compatible with various electrode types for low to high-range conductivity measurements.
• Backlit LCD / LED Display : Large, clear display shows real-time values, temperature, and device status — visible even in low-light conditions.
• 4–20 mA & RS485 Modbus Output  : ndustry-standard outputs for easy integration into DCS, PLC, or remote monitoring systems.
• High/Low Alarm Relays (Optional)
  Programmable alarm setpoints with relay outputs for process control or safety shutdowns.
• Easy Calibration : Simple one-point or multi-point calibration using standard conductivity/TDS solutions for enhanced accuracy.
