The GPR-3500 instrument has been developed for measuring 0-100% oxygen in general purpose areas. This portable oxygen analyzer features barometric pressure and temperature compensation and is supplied with stainless steel wetted parts, a flowmeter and needle valve. The LDL is 0.5% O2 (the LDL can be further enhanced with a zero calibration). This unit also displays the ambient temperature and pressure.

For oxygen purity measurements a span gas with the desired target concentration should be used.
