The Teledyne ML^®9810 Ozone Analyzer is a U.V. photometer which accurately and reliably measures ozone concentrations in ambient air. The Teledyne ML^® 9810 operates on the U.V. absorption principle (Beer-Lambert relationship) of specific wavelengths of UV light created by Ozone. One such wavelength of light is passed through a glass sample cell that alternately contains the measurement sample and then a reference sample that is selectively scrubbed of ozone. The difference in UV light attenuation between the sample and reference gas streams provides a measurement of the ozone present in the gas sample. The analyzer uses based on the U.V. absorption principle to calculate the ozone concentration in the sample.

Features:

• Ozone Measurement with Photometric Dual-Channel Technique - Provides reliable, nearly drift-free measurement.

• Secondary Ozone Scrubber - Allows independent verification of primary ozone scrubber performance to ensure valid zero reference.

• Lower Maintenance and Replacement Costs - Low slpm flow rate reduces contaminant impact on expendables, replacements costs and maintenance time.

• Automated Zero and Span capability with optional external valve manifold and external calibration source.

• U.S. EPA Equivalency Method Designation EQOA-0193-091

Teledyne ML®9811 Ozone Analyzer

The Teledyne ML^® 9811 incorporates a multi-level ozone generator with the same optical bench as the Teledyne ML^®9810 and may be used as a primary transfer standard for calibrating ozone analyzers such as the Teledyne ML^®9810. The ozone generator in the Teledyne ML^®9811 is capable of delivering up to 1 ppm of ozone to those analyzers under calibration at a flow rate of up to 4 liters per minute. The Teledyne ML^®9811 is an extremely versatile ozone calibration source and is capable of generating automatic sequences of up to 5 span points and providing a linear regression of the analyzer's responses.

Features:

• Includes Teledyne ML®9810 Features and Benefits - including secondary ozone scrubber.

• Internal UV based Ozone Generator - Generates ozone for calibration checks.

• U.S. EPA Equivalency Method Designation EQOA-0193-091
