Description

Sensor patches for non-invasive sensing of O2. Oxygen sensitive AP chemistry clear 1/4″ OD x 0.076mm (thin) or 0.76mm (thick) acrlic discs. Pack of 5 SEOX-PATCH-A oxygen sensor patches. The discs may be glued to clear container walls with RTV silicone or other clear glue. Works with DOpO2 electronics or Neofox setups.

Optional overcoats include:

W  white reflective overcoat – boosts the optical signal and minimizes refractve index effect on the sensor (reading in gas vs liquid). Slows the response to a few seconds.

BA  black acrylic eliminates ambient light interference, slows response to a few seconds

BS  black medical grade silicone. Eliniates ambient light and protects sensor from agressive chemicals such as oxidizers

note: for working in organic solvents, choose the HCR patches.
