IP66 Online Conductivity Analyzer with 1-5 Point Linear Calibration and NTC10K Temp Compensation Conductivity Controller

Accurate conductivity data starts with accurate calibration. The AEC1-T1 T2 online conductivity analyzer offers both deviation & factor correction and 1~5 point linear calibration, giving users the flexibility to match the instrument precisely to their water samples. After the electrode is connected, the actual cell constant is entered first, then the measurement can be fine-tuned using the EC offset and EC factor, or calibrated against up to five known samples sorted from low to high conductivity.

Because conductivity varies with temperature, the analyzer includes a configurable temperature compensation coefficient and displays every reading referenced to 25 ℃. A separate TDS coefficient allows the meter to convert conductivity into TDS (ppm) according to the user's requirement. With accuracy of ±1% FS for conductivity and ±0.5 ℃ for temperature, plus resolution down to 0.001 µS/cm, the instrument is well suited to demanding pure-water and process-water duties.

The 3.2 inch graphic LCD shows the measurement type, value, unit, relay state, cell constant and current outputs, while NTC10K/PT1000 automatic or manual temperature compensation keeps results stable across -10~+150 ℃. Two SPST relays, two active 4~20mA outputs and an RS485 Modbus RTU interface complete a precise, easy-to-calibrate conductivity measurement solution.

1. 1~5 point linear calibration: calibrate against up to five known samples for the highest accuracy across the measuring range.
2. Deviation & factor correction: fine-tune readings with a simple offset and factor formula.
3. Settable cell constant: enter the real K constant of the probe for correct measurement from day one.
4. Temperature compensation coefficient: every reading is referenced to 25 ℃ for consistent, comparable data.
5. Settable TDS coefficient: convert conductivity to TDS (ppm) to match your own conversion standard.
6. High accuracy and fine resolution: ±1% FS, ±0.5 ℃ and down to 0.001 µS/cm.
7. Complete, rugged instrument: 3.2 inch LCD, RS485 Modbus RTU, dual 4~20mA outputs and two SPST relays in an IP66 panel-mount housing.
