Oxilyser 3

The corrosion resistance of stainless steels depends on the quality of a very thin oxide layer, the so called 'passive layer'. Maintaining this passive layer is one of the most important aspects in maintaining the quality of stainless steel. Damage of the passive layer, in time, will cause severe corrosion.

Therefore, preserving the passive layer is a must. With the Oxilyser 3 you measure passivity fast and accurately. Besides a 0-100 passivity scale, a LED (green/red) will indicate passivity or not. The Oxilyser 3 helps you to avoid corrosion problems.

The principle of the Oxilyser 3 is based upon measuring the rest potential of the stainless steel surface combined with a sophisticated algorithm for evaluation. The electrolyte is a non toxic organic acid and filter paper strips function as electrolyte bearer.

This method is the most direct way for measuring passivity. The scale of the LCD display is divided into 100 units. Passivity of three stainless steel groups can be measured:

1. 0% Molybdenum (AISI 304, 321, 304L, Wst. Nr. 1.4301, 1.4541, etc.).
2. 2% Molybdenum (AISI 316, 316L, 316Ti, Wst. Nr. 1.4404, 1.4571, etc.).
3. Duplex stainless and 6% Mo steel such as Wst. Nr. 1.4462, duplex 2205, duplex 2507, 254 SMO and 1943 hMo.

• Checking effectivity of pickling and passivating treatment
• Checking passivity after unloading tanks with aggressive fluids like acids
• Checking passivity after cleaning/rinsing, e.g. stainless steel storage tanks, transport tanks (shipping, industry, trucks, etc)

The Oxilyser replaces the palladium chloride test as it is a more reliable and quick standard for passivity testing. Direct measurement, built in algorithm for passivity testing. The unit operates on a standard industrial quality 9V battery.
