What is the expected lifetime of my pH sensor?
Expected pH sensor lifetime is dependent on the application. Exposure to strong chemicals, elevated temperature, fluctuating pressure, and solid build-up can all impact the sensor life. As the sensor ages, a sluggish response may become more apparent, and will require more frequent calibrations to compensate for this change. The overall health of the Arc pH sensors can be seen using the quality indicator in ArcAir software. Click to learn more about sensor lifespan and expiration in the Knowledgebase article. -
What is A-length and how is it measured?
A-length refers to the insertion depth of the sensor. It's generally measured from the base of the PG13.5 mounting threads but can vary with certain styles of sensors. -
Where can I find documentation and certificates for my sensors?
Paper copies sensor information such as manuals, declarations of quality, and material certificates ship with the product. Hamilton also has several website resources to find related information. Click on the FAQ to learn more.
