ACITEK G400-COND 4-Wire Conductivity Transmitter – Reliable Liquid Conductivity Monitoring for Industrial & Laboratory Processes

Manufactured in Shanghai, China, the ACITEK G400-COND is a fixed-installation 4-wire conductivity transmitter tailored for industrial production and laboratory precision monitoring. Featuring a glass bead reinforced PBT enclosure and PP structural materials, the device delivers ultra-wide-range conductivity measurement (0.000 μS/cm – 200.0 mS/cm). It supports all mainstream 2-electrode and 4-electrode sensors, with freely selectable cell constants from 0.005 to 20 cm⁻¹, and compatible with Pt1000 and NTC 30 kΩ temperature detectors.

Equipped with a high-contrast LCD display, dual current outputs, two floating relay contacts, and dual 24VDC/230VAC power supply options, the transmitter integrates real-time sensor monitoring and preventive maintenance prompts. It supports wall, pipe and panel mounting, features intuitive operation and on-site medium calibration, and offers OEM/ODM customization with a standard one-year warranty.

The G400-COND solves key pain points of traditional conductivity monitoring with outstanding comprehensive performance. Its full-range measurement adapts to various liquid environments without equipment replacement. Dual independent outputs realize synchronous detection and signal transmission of conductivity and temperature, supporting precise system control. The built-in relay alarm function enables automatic on-site equipment linkage without additional modules.

With corrosion-resistant and durable industrial-grade housing, it adapts to harsh production environments. Meanwhile, portable calibration, factory reset function and intelligent maintenance reminders greatly reduce daily operation and maintenance costs, ensuring long-term stable and accurate measurement data.

Widely used in pharmaceutical water for injection, semiconductor cleaning water and power plant boiler feedwater monitoring. Matched with low cell constant electrodes, it realizes real-time monitoring of water ion purity and automatic temperature compensation. It triggers alarms and linkage protection when water conductivity exceeds the standard, effectively avoiding product contamination and equipment scaling, and meeting GMP and industrial safety supervision standards.

Applied to factory cooling circulating water systems, it monitors conductivity changes caused by water evaporation and salt accumulation in real time. By setting threshold parameters, it automatically controls pipeline blowdown and scale inhibitor dosing, optimizes water circulation concentration ratio, reduces fresh water consumption and chemical costs, and prevents pipeline corrosion and blockage.

Adaptable to acid-base mixing solutions and electroplating bath liquid monitoring. By configuring different cell constants for solutions of varying concentrations, it realizes closed-loop automatic control of solution concentration through relay-linked dosing pumps. It also monitors the salinity of factory wastewater discharge to ensure compliance with environmental protection discharge standards and stabilize product yield.

Installed in sewage treatment tanks and discharge pipelines, it uses conductivity data to reflect water TDS content, quickly identify sudden impact of high-salinity wastewater, and monitor the treatment effect of reclaimed water. Real-time data upload meets environmental supervision recording requirements and helps optimize biochemical treatment processes.

Used for pipeline CIP acid-base cleaning process monitoring in food and beverage factories. It judges detergent concentration and fresh water rinsing endpoint through conductivity values, avoids residual cleaning agents affecting food safety, realizes automated cleaning control, and saves water and detergent resources.

Suitable for long-term fixed monitoring of laboratory sample solutions. It supports flexible parameter calibration and cell constant adjustment, with a clear high-contrast display. The integrated temperature detection function realizes comprehensive analysis of solution properties, simplifying laboratory daily detection and instrument maintenance work.

The G400-COND boasts strong on-site adaptability. Three installation methods adapt to equipment rooms, outdoor stations and laboratory cabinets. The universal power supply design matches mainstream industrial power systems, and standard 4–20mA analog signals are seamlessly compatible with PLC, DCS and monitoring hosts. It supports most mainstream sensors on the market, reducing equipment upgrade costs. Customized services can meet the personalized needs of system integrators and manufacturers.

The ACITEK G400-COND conductivity transmitter is a multi-scenario, high-stability monitoring instrument integrating detection, alarm and signal transmission. With full-range measurement, intelligent control, simple operation and strong environmental adaptability, it covers mainstream monitoring scenarios such as industrial water treatment, chemical production, food processing and laboratory testing. With reliable quality and perfect after-sales guarantee, it provides efficient, low-cost and automated conductivity monitoring solutions for various industries.
