Online Conductivity Analyzer Explained: AEC1-T1 T2 Features, Ranges and Applications

If you are researching online conductivity analyzers, this guide explains what they do and how the Daruifuno AEC1-T1 T2 delivers continuous conductivity monitoring for water treatment and industrial processes.

What Is an Online Conductivity Analyzer?

An online conductivity analyzer is an instrument that continuously measures the electrical conductivity of a solution and reports the result in real time, typically to a display, a relay. Because dissolved ions carry current, conductivity is a fast, reliable indicator of water purity, salinity and dissolved solids. The AEC1-T1 T2 uses a proven two-electrode measurement method and is designed for permanent panel mounting.

What Does the AEC1-T1 T2 Measure?

Key Features at a Glance

• Accuracy of ±1% FS for conductivity and ±0.5 °C for temperature
• NTC10K / PT1000 automatic or manual temperature compensation
• Two SPST relays (3A 250V AC) and two active 4–20mA outputs
• RS485 interface supporting Modbus RTU
• 3.2 inch graphic LCD, IP66 panel-mount housing, about 500 g

Where Are Online Conductivity Analyzers Used?

Common applications include pure water and RO/DI systems, desalination, boiler and cooling tower water, food and beverage processing, wastewater treatment and aquaculture. In each case the analyzer provides the continuous data needed to protect equipment and maintain water quality.

Frequently Asked Questions

What is the conductivity range of the AEC1-T1 T2?
0–20 mS/cm, with a resolution down to 0.001 µS/cm.

Does it measure more than conductivity?
Yes — it also measures resistivity, TDS, salinity and temperature.

Can it connect to my control system?
Yes, via RS485 Modbus RTU or the two 4–20mA analog outputs.

How an Online Conductivity Analyzer Works

In a two-electrode analyzer, an alternating voltage is applied across two contacts in the sensor. The resulting current is proportional to the ions present in the solution, and the controller converts this into a conductivity value using the cell constant. Because the method is simple and robust, it is widely used for continuous monitoring in clean water and industrial processes alike. Temperature is measured at the same time and used to normalise the reading to 25 °C.
