Features & Benefits

MODEL 65 PERCENT OXYGEN PROBE

The MODEL 65 Percent Oxygen Probe is designed for measuring percent oxygen levels exclusively in NON-FLAMMABLE gases. It will provide a very accurate, stable, long life, linear analog output signal over a preconfigured range of 0-25%, 0-50% or 0-95% of oxygen. The MODEL 65 is simple to mount indoors or outdoors and extremely accurate and stable over a wide temperature range, as well as being immune to changes in barometric pressure.

INCREDIBLE VALUE

The unit contains a unique zirconium oxide oxygen sensor that gives the probe up to a 10-YEAR LIFE expectancy, making it virtually maintenance-free. It is designed for easy integration into an operator’s system and functions as a standalone oxygen sensor, making it a perfect fit when more costly alarms and controls are not required.

IDEAL OEM SOLUTION

The MODEL 65 is a perfect fit for OEM applications, requiring measurement of percent oxygen levels in inert gases, such as gas blanketing systems, nitrogen or oxygen generators, refrigeration units and many others. At only 2.0” long x 2.2” in diameter (51mm x 56mm), this dependable, rugged, compact probe can be mounted virtually anywhere.
