Calibration procedures vary by model (e.g., Minox i, GPR series). Generally, electrochemical sensors are calibrated using ambient air (20.9% O2) or a known span gas. Refer to your specific instrument's user manual for the correct procedure.
Sensor precision and lifespan depend on the application and model. In standard ambient air conditions, many PST electrochemical sensors have a life expectancy of 12 to 36 months.
Software and firmware updates for PST instruments, including Michell and Rotronic product lines, can typically be found in the Support or Downloads section of the official Process Sensing Technologies webpae.
Many PST products, such as the Minox i and GPR series, are ATEX and IECEx certified for intrinsically safe operation in hazardous environments. Always check the specific certification label on your device before use.
