Oxyliser

• Simple and robust device - Just a small meter with 2 cables and a shockproof electrode
• Easy to understand - Takes 5 minutes to understand the procedure
• Effective method - Just the type of steel measured must be known
• Accurate results - Green light : OK. Red light : Not OK. Additional info from digital reading
• Replaces the palladium chloride test

Details

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

PRINCIPLE
The principle of the Oxilyser is based upon measuring the restpotential of the stainless steel surface combined with a sophisticated algorithm for evaluation. The electrolyte is a non toxic organic acid and filterpaper 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.

APPLICATIONS
• Checking effectivity of pickling and passivating treatment.
• Checking effectivity of rinse treatment
• Checking passivity after unloading tanks with aggressive fluids like acids and orange juice.
• Checking passivity after cleaning/rinsing, e.g. stainless steel storage tanks, transport tanks (shipping, industry, trucks, etcetera).
ADVANTAGES/ SPECIFICATIONS
• The Oxilyser replaces the palladium chloride test as it is a more reliable standard for passivity testing.
• Direct measurement, built in algorithm for passivity testing.
• Objective result on LCD display. Scale 0 (active) to 100 (fully passive).
• Passive or not LED passivity indication for three stainless steel groups.
• Shockproof Epoxy Double Bridge Ag/AgCl2 reference electrode. Gel filled, this makes measuring “up side down” possible.
• Measuring procedure fits into QA/QC procedures (ISO 9001, 9002, etc).
• Impedance resistance > 10 MOhm. Test procedure for reference has been included.
