Twin Commander 690C: pH Meters

TPI’s pH meters are capable of measuring a wide pH range from 0.00 to 14.00, accommodating most standard applications from acidic to basic solutions.

TPI’s pH meters provide high accuracy, typically ±0.02 pH units, ensuring reliable measurements in professional and industrial environments.

Yes, TPI’s pH meters include automatic temperature compensation, which adjusts readings based on solution temperature for more precise measurements.

When not in use, the meter’s electrode should be stored in a pH storage solution to maintain hydration. Avoid storing the electrode in distilled water, as this can damage the sensor and shorten its lifespan.

pH meters should typically be calibrated before each use to ensure accuracy, particularly in professional or precise testing environments. Depending on the frequency of use, calibrating daily or weekly may be sufficient for general applications.

Regular calibration with standard buffer solutions at specific pH values (like pH 4, 7, and 10) helps maintain the instrument's reliability, especially in changing environmental conditions or when switching between solutions with differing pH levels.
