Measures the purity of oxygen generated by PSA oxygen concentrators. Requires NO expensive replacement sensors, never needs calibration. Accurate to within plus/minus 1%. Made in the USA for High Volume Oxygen.
To operate, take the 3/8” OD oxygen line leaving your oxygen concentrator and connect it to the barbed fitting marked “inlet”. When oxygen is flowing, press the activation button, wait about 10 seconds, and the percentage of oxygen purity will display. The device will automatically power off after 60 seconds.
Requires a 9 volt battery (included).
Includes a 1 year manufacturer’s warranty.
Note: You must restrict the oxygen flow to less than 10 liters per minute to get an accurate reading.
WARNING: The maximum input pressure is 30 PSI. If you exceed 30 PSI you may permanently damage the unit. Not for use with oxygen cylinders.
CANCELED ORDERS: If you make a purchase and subsequently cancel, a 5% restocking fee will apply.
