What does -YAU, -NAU or -SA stand for in the oxygen sensor spot names and what is the difference between those sensor types?

SP-PStx-YAU:

• These sensor spots can be autoclaved and cleaned (CIP, 3 % H₂O₂, acidic agents like HCl and H₂SO₄ at max. 4 – 5 %).
• They must be glued to a surface with silicone glue.
• The support material of these sensors is glass with about 1.1 ± 0.1 mm thickness.

Example: Oxygen Sensor Spot SP-PSt3-YAU

 

SP-PStx-NAU:

• These sensor spots cannot be autoclaved, however cleaning with e.g. ethanol is possible.
• They must be glued to a surface with silicone glue.
• The support material of these sensors is polyester with about 125 µm thickness (sensor coating not included).

Example: Oxygen Sensor Spot SP-PSt3-NAU

 

SP-PStx-SA:

• These sensor spots cannot be autoclaved and can only be cleaned by rinsing with aqueous solutions.
• These sensors are self-adhesive and can be attached to glass and almost any plastic surfaces.
• They are usually used in single-use applications. Cleaning with Ethanol is NOT possible (it would dissolve the glue of the self-adhesive layer).
• The support material of these sensors is polyester with about 23 µm thickness (sensor coating not included).
