Unlike any other

The sensor design allows measuring of oxygen concentrations from 0,50 to full 100.00 %, regardless of gas pressure. High oxygen concentrations do not affect the sensor’s lifespan. The absolute precision of reading is ±0,5 % within the full measuring scale. Unlimited Shelf Life while stored in the normal atmosphere. Proved lifespan of over 10 years while operated in gas with >5 % of oxygen.

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 4–20 mA 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.
