Product Code: PS-3250

Description

Replacement cap for PS-3246 optical dissolved oxygen sensor. (The version with the 1 m cable). Cap contains a glass window with a phosphorescent coating covered by a neoprene scratch guard. Dissolved O2 quenches phosphorescent film, timed decay measured to find O2 levels.

Cap is shipped with coefficients needed for optimum calibration. Use without entering coefficients renders a few percent higher error on readings.
