Model T703U - Teledyne Advanced Pollution Instrumentation
The Model T703U is a microprocessor controlled ozone calibrator for precision gas analyzers. Expanded ozone audit levels have created a need for precise ozone calibration well below the capabilities of standard calibrators. The Model T703U is designed to meet the requirements of ultra-low ozone production.In addition to a high range with similar performance to the Model T703, the Model T703U has the capability to generate ozone in a low range, or "fractional" mode, for producing ozone levels down to 3 ppb, with exceptional accuracy. Flow rate and lamp intensity are adjusted to deliver a specified ozone concentration by volume. The temperature and pressure compensated photometer, identical to that of the Model T400 ozone analyzer, provides feedback control of the UV lamp intensity, assuring stable ozone output. A nearly unlimited number of calibration sequences may be programmed into the non-volatile memory of the T703U, covering time periods up to a year.

Model T100U - Teledyne Advanced Pollution Instrumentation
The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance. A separate UV detector allows the instrument to continuously correct for variations in lamp intensity. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interferents.

Omni-λTripple Series - ZOLIX
Omni-λ 500 Triple Monochromator/ SpectrographThe Triple Monochromators/Spectrographs include three 500 mm focus monochromators which are with fine alignment. The first two monochromators as the dispersion subtraction are used to reduce the stray light. The third monochromator as dispersion sum configuration is used to improve the resolution. And each unit can work well as the monochromator, and the two unit can also be used as the double monochromator. The first and the second monochromator are the side entrance and double exits, the third monochromator is the double entrances and double exits, it is easy to connect the CCD and PMT, the single channel detectors. There are three import gratings in each monochromator, and the spectral range is located in deep UV region, the middle UV and visible region. Each grating reflectivity can be up to 70% in their spectral region. Mainly used in high grade Raman spectroscopy measurement, such as UV-resonance Raman spectroscopy.

Model T400 - Teledyne Advanced Pollution Instrumentation
The Model T400 UV Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in ambient air.A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically, a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone measurement.

Model CA6 - Electro-Chemical Devices
The CA-6 UV Analyzers are a family of on-line sampling analyzers that use UV absorption to perform an analysis. The analyzers are configured to perform analysis over a wide range of values for each parameter measured, Ammonia, Nitrate and COD 254 nm. The CA-6 UV Analyzers are easy to start up and use, simply connect the sample, waste and cleaning solution/reagent lines and then power up the Factory Calibrated analyzer. Wall mounting hardware is standard but an optional benchtop stand with reagent holder is also available. Accessing information or customizing an analysis routine are easily accomplished with the simple, user friendly menu structure and touch screen interface.
