Teledyne API

The Model T100 uses the proven UV fluorescence principle, coupled with a state of the art user interface to provide easy, accurate, and dependable measurements of low level SO2.

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.

The Model T200 NO/NO2/NOx analyzer uses the proven chemiluminescence detection principle, coupled with state-of-the-art electronics to allow accurate and dependable low level measurements for use as an ambient analyzer or dilution CEMS monitor.

A unique AutoZero feature provides superb stability by continuously correcting for zero drift, while advanced Adaptive Filtering allows the analyzer to optimize performance under changing conditions. The Model T200 includes a permeation inlet dryer for ozone generation to provide excellent reliability with no periodic replacement required. A catalytic exhaust ozone scrubber is standard for maximum safety and pump life.

The Model T300 measures low ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law.

Using a Gas Filter Correlation Wheel, a high energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 14 meters. The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing extreme sensitivity.

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.

The next breakthrough in ambient particulate monitors. The Model T640 PM Mass Monitor. The T640 delivers 1-min or better time resolution with exceptional sensitivity and precision. The instrument is very low maintenance and requires no sample media for minimal cost of operation.​

The Teledyne API Model T640 with 640X Option is a real-time, continuous particulate matter (PM) mass monitor that uses scattered light spectrometry for measurement. The T640 measures 2.5 PM, and the 640X Option measures 2.5, 10, and coarse PM. ​​​

The Model T700 is a microprocessor based calibrator for precision gas analyzers.  Using highly accurate mass flow controllers combined with compressed sources of standard gases, calibration standards are provided for multipoint span and zero calibrations using up to 4 gas sources.

The Model T700 can be equipped with an optional UV ozone generator for accurate, dependable ozone calibrations, and to enable production of NO2 when blended with NO gas in the included, internal gas phase titration (GPT) chamber. An optional photometer allows even more precise control of the ozone generator giving accurate and dependable ozone calibrations and enhanced GPTs.  To ensure the highest accuracy of NO2 output, the T700 with the photometer option can measure the ozone concentration prior to performing a GPT. A nearly unlimited number of calibration sequences may be programmed into the non-volatile memory of the Model T700, covering time periods up to a year.

The T701 adds Modbus TCP/IP connectivity to the proven reliability and performance of our zero air systems.  This allows remote monitoring of key instrument functions including dewpoint status, scrubber temperature, box temperature, and output pressure.  Additionally, this digital access provides the ability to remotely disable the internal pump, allowing longer service intervals and less power consumption.  The user can also remotely start instrument warm-up prior to arrival at the site.

The T701 is a fully self-contained source of clean, dry air for dilution calibrators. It can also be used to create purge air for permeation tube ovens or burner air for FID analyzers.  The T701 includes a dewpoint sensor, an oil and diaphragm-free pump, and scrubbers to remove SO2, NO, NO2, O3, H2S, and NH3.  Optional high performance scrubbers are available to remove CO and Hydrocarbons.
