For those who need to integrate their ozone monitor into a separate system such as an air pollution monitoring package, we offer the Model OEM-106 series where the entire ozone monitor is mounted on a single printed circuit board. The liquid crystal display and power switch may be detached and mounted outside the customer's custom enclosure. With the exception of our Personal Ozone Monitor (POM), this is the most compact UV-absorbance-based ozone monitor available on the market. The Model OEM-106-L has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA–0914–218. Choice of four different optical benches allows for four different ozone concentration ranges as summarized in the following table.

Specifications for Different Optical Benches

Model Range Resolution Precision & Accuracy
106-L 0-100 ppm 0.0001 ppm (0.1 ppb) Higher of 0.002 ppm (2 ppb) or 2% of reading
106-M 0-1,000 ppm 0.01 ppm Higher of 0.01 ppm or 2% of reading
106-MH 0-10,000 ppm (0-1 vol%) 0.1 ppm Higher of 0.05 ppm or 2% of reading
106-H 0-20 wt% O2 or Air
0-14 vol%
0.01 wt%
0.01 vol%
Higher of 0.01 wt% or 2% of reading
