The Series 3500 is the loop powered version, and the Series 3510 is the AC powered (115/230 VAC, 50-60 Hz) counterpart and is recommended when AC power is available or preferred. Also, available in optional 24 VDC.
NOW FEATURING A CO2 RESISTANT SENSOR
A nemesis for many conventional “fuel cell” type trace oxygen sensors are their inability to measure oxygen in gases. Carbon dioxide reacts with potassium hydroxide electrolyte to form carbonic acid and in short time destroys the sensor. Not anymore. We offer an optional CO2 tolerant trace oxygen sensor with proprietary electrolyte.
