FAQ

How do I communicate with an Arc sensor?

Arc sensors have a built-in micro-transmitter within the sensor. ArcAir software is a powerful tool to access data, configure and calibrate the sensor. This can be done with Bluetooth wireless communication or with a wired connection directly to a PC.

FAQ

When should I calibrate my DO sensor?

The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications calibration can be performed before sterilization; however many customers choose to calibrate after sterilization as well.

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.
