FAQ

Does carbon dioxide sparging impact my DO measurement?

CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed.

FAQ

How much torque is needed to install a sensor with PG13.5 threads?

Sensors with PG13.5 threads rely on the o-ring to seal against process pressure. Finger-tight (approximately 2 Newton Meter or 18 inch-lb) should be sufficient to install the sensor without leakage. Additional tightening beyond this can deform the o-ring or strip the threads.

FAQ

Does temperature impact my oxygen measurement?

Yes, in a closed system, gas phase temperature is directly proportional to pressure and therefore measured oxygen content. In solution, temperature is inversely proportional to dissolved oxygen content.
