Incredible Value

The MODEL 65 is designed to be integrated into an operator’s system and function as a standalone oxygen sensor. It is virtually maintenance free, extremely accurate and stable over a wide temperature range (0-130 0 F) and immune to changes in barometric. Additionally, it uses a unique zirconium oxide sensor with a 10-year life expectancy, requiring only annual calibrations.

Perfect Percent Oxygen OEM Solution

The MODEL 65 is ideal for OEM applications measuring percent oxygen levels in inert gases, such as: gas blanketing, nitrogen/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 virtually be mounted anywhere.
