The DF-330 Oxygen Analyzer includes Delta F's new solid-state coulometric sensor. Measurement ranges from ppm levels to 100% are possible with this new analyzer. A voltage is applied across the DF-330 Oxygen Sensor that allows oxygen molecules to move through the solid electrolyte for measurement. No reference gas is required to make the measurement, thus an accurate output can be relied upon each time. The sensor can be mounted in-situ, or a sample can be extracted from the gas patch to flow through the sensor. The digital electronics offer an array of options for alarms, relays and RS232 or RS485 output. OEM versions are available if sensing capability is the only requirement.
