Teledyne ML^®9850 Sulfur Dioxide Analyzer

The Teledyne ML^® 9850 is a U.V. Fluorescence sulfur dioxide analyzer designed to measure ambient levels of SO2. The measurement principle relies on the excitation of the SO2 molecule which occurs in the presence of a specific wavelength (214 nanometers) of U.V. light and subsequent relaxation which produces a photon of light. A photo multiplier tube allows the light emissions to be measured as the SO2 molecule returns to a ground state. A hydrocarbon scrubbing system, containing no consumable materials, removes interfering hydrocarbons prior to the ambient sample being measured. The reference detector continuously monitors the intensity of the U.V. lamp and allows use of a ratiometric measurement technique which compensates for lamp degradation.

Features:

• Greater Lamp Lifetime - UV fluorescence technology provides maximum sensitivity and long lamp lifetime, thus reducing operating cost.

• Non-Consumable Hydrocarbon Removal System (Kicker) - Provided standard, this permeation membrane device provides hydrocarbon removal without costly scrubbing mediums.

• Long Term Measurement Stability- The Teledyne Teledyne ML®9850 captures higher valid percentages of data, even under a poorly controlled environment.

• Low Maintenance - No chopper means no need to replace belts or motors.

• U.S. EPA Equivalency Method Designation EQSA-0193-092.
