Introduction
An online conductivity controller is an instrument used for continuous, real-time measurement and control of the electrical conductivity of a liquid in an industrial or water treatment process, and it is used for monitoring and controlling water quality, chemical concentrations, and process conditions. The controller consists of a conductivity sensor or cell, which is installed in the process stream or a bypass line and measures the electrical conductivity of the liquid, which depends on the concentration of dissolved ions, and a transmitter or controller unit that processes the signal, displays the measured value, and provides outputs, such as analog signals, relays, and alarms, for control and monitoring; the controller can be configured with set points to trigger alarms or to control dosing pumps, valves, and other devices to maintain the conductivity within a desired range. Online conductivity controllers are used in water and wastewater treatment for monitoring and controlling the conductivity of treated water; in the power industry for monitoring boiler water, cooling water, and steam condensate quality; in the chemical and pharmaceutical industries for process control and concentration monitoring; in the food and beverage industry for cleaning-in-place (CIP) monitoring; in desalination; in aquaculture; and in environmental monitoring, and they are available in various configurations, with features such as automatic temperature compensation, multiple measurement ranges, digital displays, data logging, and communication interfaces. With their continuous measurement and control capability, online conductivity controllers are essential for process monitoring and water quality control.

FAQ
Q1: What testing scenarios is this controller mainly applied to?
A: The online conductivity controller is used in water treatment plants, pharmaceutical manufacturing, food and beverage production, power generation, semiconductor manufacturing, chemical processing and industrial facilities to continuously monitor and control the conductivity of water and process fluids in real time. It supports pure water and ultrapure water quality monitoring, reverse osmosis and deionization system control, boiler and cooling water treatment, pharmaceutical water system monitoring (WFI, purified water), semiconductor process water quality control, food and beverage water treatment, and industrial process fluid monitoring. The continuous measurement enables automatic control, alarm notification and data logging for water quality management and regulatory compliance. It is essential for water treatment, pharmaceutical, power, semiconductor, food and industrial facilities requiring continuous conductivity monitoring and control for water quality management, process optimization, regulatory compliance, equipment protection and energy efficiency, where conductivity is a fundamental indicator of water purity, dissolved ion content, membrane performance and treatment system effectiveness in industrial and municipal water systems.
Q2: What standards does the controller comply with?
A: The online conductivity controller supports methods referenced in ASTM D1125 for water conductivity, ISO 7888, pharmacopoeial requirements for water conductivity (USP 645, EP), and relevant GB/T standards including GB/T 6908 for boiler water. The hardware complies with applicable industrial safety and electromagnetic compatibility standards. Calibration should use certified conductivity standards traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole controller including sensor is covered by a 12-month warranty. The electronics, display, relays and controller are covered, while conductivity sensors, cables and fuses are consumables or accessories. Damage from improper installation, corrosive fluids beyond rating or unauthorized repair is excluded. Extended service contracts are available for industrial monitoring equipment.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained personnel familiar with water treatment, conductivity measurement and process control. We provide operation manuals, training and application support. Proper sensor installation, calibration, control parameter setup and maintenance are important for accurate, reliable continuous monitoring.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified conductivity standards recommended every 3-6 months, or more frequently for critical pharmaceutical water monitoring. Sensor cleaning and inspection per manufacturer schedule based on water quality. Routine verification with a portable meter or standard. Full system performance check annually. Temperature compensation verified periodically.
Q7: Are supporting consumables universal?
A: Conductivity sensors, calibration standards and cables are available from multiple suppliers, though instrument compatibility should be verified. Long-term consumable and maintenance cost is moderate depending on water quality and sensor fouling.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes conductivity range, sensor type (contacting, inductive), temperature compensation, control relays, communication protocol and enclosure rating. Additional sensors, cables and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the controller, sensor and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for industrial water treatment setup. Remote guidance is provided.
Q10: What types of water are compatible with this equipment?
A: The online conductivity controller monitors water and process fluids within the conductivity range, temperature rating and sensor material compatibility. Highly corrosive fluids may require special sensor material (inductive or alloy). Very pure water (ultrapure) requires special low-conductivity sensors and proper temperature compensation. Users should select appropriate sensor type for the water quality, install the sensor in a representative location with proper flow, calibrate regularly with certified standards, maintain and clean the sensor per manufacturer schedule, set appropriate alarm and control setpoints, and ensure proper temperature compensation for accurate conductivity measurement. For pharmaceutical water systems, the installation, calibration and monitoring should follow pharmacopoeial requirements including USP 645 or equivalent.
