1. INTRODUCTION, SPECIFICATIONS, APPROVALS, &
COMPLIANCE
Teledyne API’s microprocessor-controlled Model T400 measures low ranges of ozone in
ambient air using a method based on the Beer-Lambert law that relates the absorption of
light to the properties of the material through which the light is traveling over a defined
distance. In the T400 the intensity of an ultra violet light is measured after it passes
through a chamber, called the sample cell, where it is absorbed in proportion to the
amount of ozone present. Every three seconds, a switching valve alternates measurement
between a gas stream containing ozone and a stream that has been scrubbed of ozone.
These measurements are calculated along with the ambient sample gas pressure and
temperature to provide a true, stable ozone measurement.
The T400 tracks operational parameters and issues warnings if they fall outside
diagnostic limits, as well as stores easily retrievable data. Proprietary software allows
configurable data acquisition capability that can be triggered conditionally or
periodically, enabling operators to perform predictive diagnostics and enhanced data
analysis by tracking parameter trends. Reports can be downloaded onto a USB flash drive
or via the I/O ports. Operators can also view real-time graphing with one touch of the
interface screen.
