OXYMAT 64 can control the measurement of oxygen concentration in the smallest tracks, even down to the smallest measuring area of 0…10 ppm. This is for special interests in arrangements for the aerial decomposition, in the technical gas production and with the welding from high-alloy steel, titanium and others under protective atmosphere. Other application possiblilities come up in hardening shops, in the chemical industry and the food industry.

OXYMAT 64 works with ZrO2 sensors, which is measuring gas with steady flow through a 650°C heated, pipe-shaped sensor. The outside of the sensor is put out in ambient air and works as an authoritative electrode. By the concentration differences on both sides rules a different partial pressure. Since ZrO2 is led electrically with 650°C, an ion wandering occurs in the direction of the lower partial pressure. A potential difference arises between both electrodes where a measurement of the oxygen concentration in the measuring gas is achieved.

Depending on the application a catalytic inactive ZrO2 sensor and a catalytic active ZrO2 sensor are both available and operation is intutive with menu-driven operation.
