ATTENTION!

Never immerse probe in high concentration acid or alkaline (undiluted pH minus liquid)!

Never immerse probe in hot liquids, because this may damage the probe.

Air bubble in probe does not cause any problems, because holding the instrument during measurement will cause the bubble to rise up, and stay away from the sensor.
