pH Sensor (PH-BTA)
Specifications and User Guide


Primary Test: Does it read approximately 4 in its storage solution? Note: A reading of 13 to 14 indicates 0 volts and might mean that the sensor is defective or damaged.

Secondary Test: Take readings in fresh buffers, NOT distilled water! If no buffers are available, try it in vinegar (~ pH 2.5 to 3.5) and ammonia (~ pH 10.5 to 11.5). If readings do not change when the sensor is placed in different solutions, the sensor is possibly defective or damaged.

Calibrate? Usually no. However, for the most accurate measurements with this sensor, we recommend calibration. It is a simple process that only takes a few minutes. Custom calibrations can also be stored directly onto the sensor.
