AMTRA | Technik | Testers | Conductivity & TDS Calibration Kit

Calibration solution for: AMTRA DIGITAL CONDUCTIVITY & TDS TESTER ATC is an electronic tester that allows the rapid and precise determination of the water conductivity (EC in µS and TDS in ppm) of your aquarium. Practical “pen” shape so it can be carried and used anywhere. The possibility of recalibration and automatic temperature compensation are among the main advantages of this device suitable for both beginners and experienced aquarists. Measuring scale EC: 0-9990 µS / TDS: 0-9990ppm 0.1-80.0°C / 32.0-176.0°F Instructions for use: Remove the protective cover from the electrode. Press [ON/OFF] and insert the electrode into the solution to be tested. When the numbers on the display are stable, press [HOLD], remove from the solution and read the value. Turn off with [ON/OFF] (after 5 minutes of inactivity the instrument turns off automatically). Clean the electrode preferably with osmotic water before putting it back in the package. By pressing [SHIFT] you can view the TDS or EC reading and switch from the °C scale to the °F scale for the temperature. AMTRA DIGITAL CONDUCTIVITY & TDS TESTER is equipped with ATC system: automatic temperature compensation during measurement! Calibration: 1. Turn on the tester and immerse the electrode in a standard buffer solution (e.g. 1413 µS) 2. Press the SHIFT button for 3 seconds: the word CAL will appear on the display in place of the detected temperature 3. You can now set the correct parameter read by using the SHIFT button to increase the measured value or HOLD to decrease it 4. Once the reading has stabilized, press the “SHIFT” button for 3 seconds, wait until the word CAL leaves the place again to the detected temperature. Calibration Completed. Caution: The instrument must be recalibrated under the following conditions: after a long period of inactivity or a long period since the last calibration, following frequent use, or when high measurement accuracy is required. If the electrode is exposed to air for a long time, it will dry out, resulting in slow and unstable readings. Simply soaking the electrode in osmosis water for a few hours will resolve this issue.
