[Video Introduction] Introduction to WIKA Calibration Technology

Why is it important to have oxygen embargo processing and oil and grease-free conditions in the oxygen supply line? Oxygen itself is not flammable, but it can promote the combustion of other substances and can particularly trigger the spontaneous ignition of oils and fats. Substances that do not burn in the air may ignite spontaneously in oxygen or oxygen-enriched air. This phenomenon can occur even with an oxygen concentration of just a few percent, and especially oils and fats (including ointments, gels, and disinfectants) can react explosively when in contact with oxygen. WIKA has responded to the increasing market demand by developing a special cleaning method specifically for its products. Cleaning is performed after product completion and before packaging, and residual hydrocarbons are measured. The following values are set as standards: Hydrocarbon limit: maximum 200 mg/m² (according to ISO 15001:2012) Particles and fibers: limit value 1000 μm The results of the assessment are recorded in the inspection certificate. A protective cap is attached to the pressure connection of the cleaned and inspected digital pressure gauge, and the entire equipment is sealed with foil. Furthermore, the product label states "Contains no oxygen, oil, or grease." This measurement is conducted for each individual digital pressure gauge.
