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
An in-situ oxygen sensor for combustion control that measures oxygen directly in the hot zone of re-heat furnaces, boilers and incinerators.
The SuperOX is an oxygen sensor for combustion control in re-heat furnaces, boilers and incinerators. This in-situ sensor measures the percentage oxygen concentration directly in the combustion area of high-temperature furnaces, boilers and incinerators. It is intrinsically safe and produces a low millivolt output based on the oxygen content of the atmosphere.
The sensor is used in glass melting operations, glass furnaces, ceramic kilns and exhaust stacks. It enables round-the-clock monitoring of combustion stack oxygen and interfaces with existing combustion control systems, which makes air-fuel ratio control possible.
A rugged construction gives long service life in ash-laden environments, and a dedicated air-cooled head maintains positive pressure in harsh conditions. The probe is rebuildable, requires no calibration and its performance can be verified in the field through an external port.

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.

A reinforced spring assembly compensates the differential thermal expansion of ceramic parts and sheath in probes longer than 1000 mm.
