Go Wireless® pH (GW-PH, discontinued)
Specifications and User Guide

TROUBLESHOOTING
– Primary Test: Press the power button on the sensor to turn it on. (The red LED will be flashing.) Start the data-collection app and select the sensor from the list of available sensors. (The green LED will be flashing.) It should read approximately 4 in its storage solution.

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

CALIBRATION
For many experiments, calibrating the pH Sensor is not required.
For the most accurate measurements with this sensor, we recommend calibration. It is a simple process that takes only a few minutes.
See Specifications and User Guide for detailed instructions.
