Gold Probe Oxygen Probe
The world's best-selling zirconia oxygen probe measures and controls oxygen, dew point and carbon potential in heat treatment furnace atmospheres.
Oxygen probes
A reinforced spring assembly compensates the differential thermal expansion of ceramic parts and sheath in probes longer than 1000 mm.
The improved, reinforced spring assembly of the Gold Probe XL compensates far better for the difference in thermal expansion between the ceramic components of the probe and the outer sheath. It is particularly recommended for pit and muffle furnaces, where probes longer than 1000 mm are typically used.
Apart from the reinforced spring design, the XL retains all the characteristics of the standard SSi Gold Probe: the same zirconia sensing cell, the same accuracy and repeatability, and full interchangeability with other manufacturers' probes and instrumentation.

The world's best-selling zirconia oxygen probe measures and controls oxygen, dew point and carbon potential in heat treatment furnace atmospheres.

A patented diffused ceramic CERMET coating protects the sheath against temperature and carbon erosion, extending probe life in aggressive carburising atmospheres.

Measures oxygen from 510 °C upwards, covering nitriding, ferritic nitrocarburising and pre- and post-oxidation processes at low temperatures.
