The epitome of reliability

The OXY F analyzer had always been the flagship of Nitrogen analyzers. The precision of a paramagnetic sensor, with the resilience of a Zirconia, yet operating with fuel-cell technology. The 2nd generation keeps the same qualities, extending them through system integration, ergonomy of use, and auto diagnostics.

Unlike any other

The embedded solenoid valves protect the sensor when Oxygen concentration rises above safe limits, the same as during its storage period. Inner flow control and many other unique technical enhancements contribute to outstanding stability and exceptional lifespan of the sensor.

Innovative and compatible

Integrated display showing reading results and allowing calibration without any additional device. Fulfilling dimensional requirements for most of the existing relevant PSA devices. Both 4-20mA and Modbus RTU interface. System for logging operation conditions accessible by Android application.

The quality you deserve

In GRYF, we believe that there is no space for compromise in engineering. That is why thousands of our customers worldwide choose our technologies for projects to have the highest reliability and superior precision.
