Online Conductivity / Resistivity / TDS / Salinity Meter T6030
Industrial online conductivity meter is a microprocessor-based water quality online monitoring control instrument, the salinometer measures and supervises the salinity (salt content) by conductivity measurement in fresh water. The measured value is displayed as ppm and by comparing the measured value to a user defined alarm set point value, relay outputs are available to indicate if salinity is above or below the alarm set point value.Constructed with durable materials like titanium or graphite, it resists corrosion in harsh applications such as seawater desalination, industrial wastewater, and cooling towers. Integrated with 4-20mA and RS485 (Modbus) outputs, it provides real-time data for remote monitoring systems. Key features include wide measurement ranges (0-2000 µS/cm to 0-2000 mS/cm), self-cleaning options, and high reliability for industrial automation. This meter is essential for irrigation management, boiler feedwater control, and aquaculture to maintain precise salt and mineral levels. -

CS3540 Industrial Electrical Conductivity Sensor
Electromagnetic (inductive) conductivity sensor is a non-contact device designed to measure the conductivity of highly corrosive, fouling, or high-temperature liquids. Unlike traditional electrode sensors, it uses two toroidal coils encapsulated in corrosion-resistant material such as PFA or PVDF. An alternating current in the drive coil induces a voltage in the liquid, and the receiving coil measures the resulting current, which is proportional to conductivity. This design eliminates electrode fouling and polarization, ensuring long-term stability in harsh environments. Electromagnetic sensors are ideal for measuring strong acids, alkalis, saline solutions, and wastewater. They provide a wide measurement range (e.g., 0–2000 mS/cm) and feature automatic temperature compensation. With analog and digital outputs (4-20mA, Modbus RS-485), they integrate seamlessly into industrial control systems for reliable online monitoring. -

Electrode performance is defined by its cell constant, material, and construction. Materials range from durable graphite for harsh or fouling media to premium platinum for high accuracy and stability. Selecting the correct cell constant (e.g., K=0.1 cm⁻¹ for high purity water, K=1.0 cm⁻¹ for general use) is critical for optimal accuracy. As the primary interface with the process, the conductivity electrode, when paired with a quality transmitter, forms an indispensable system for real-time, reliable water quality and process control. -
CS3732 Conductivity Sensor
electrode is a fundamental sensor designed to measure the ability of an aqueous solution to conduct electrical current, which directly correlates with its total concentration of dissolved ions. This key parameter is essential for assessing water purity, controlling chemical processes, and monitoring environmental compliance across industries like pharmaceuticals, power generation, food and beverage, and wastewater treatment.
The core of the electrode is a measurement cell containing at least two conductive elements. When an alternating current is applied, the ions in the solution complete the circuit between these elements. The resulting conductance is measured and, along with the cell's geometric constant (cell constant, K), is used to calculate conductivity. Modern electrodes are almost always integrated with a temperature sensor (typically a Pt100 or Pt1000 RTD) for automatic compensation, as conductivity is highly temperature-dependent. Common designs include two-pole cells for general use and four-pole (or four-electrode) cells, which use separate current and voltage rings to minimize polarization effects and extend measurement range, especially in high-conductivity applications. -
