MEXA-7000 Version 2 Analitical System

   Version 2 builds on the features of the original MEXA-7000, incorporating new analyzers, new sample handling techniques, and extended controller functions. Measures raw and CVS-diluted exhaust gases from all vehicle and engine types for basic R&D, model certification, quality testing, and durability. Includes up to 10 analyzers in a single, compact cabinet to measure THC, CO, CO₂, O₂, NO/NOx, HC, N₂O, SO₂, CH₄, and SF₆ over a wide dynamic range. Modular sampling and analysis components provide flexibility and expandability in system configuration. Low sample flow requirements minimize operational costs and allow testing of  engines with minimal exhaust output.

FEATURES

Modular components provide flexible system configuration.

Compact cabinets fit in the smallest test cells.

small sample flow requirement - 9 to 13 L/min for cold systems; 11 to 15 L/min for heated systems - minimizes span gas usage and operational costs.

Fast system response time minimizes alteration of the concentrations in the sample lines.

(Typical Td + T₉₀ is 5 seconds or better with a 16-foot/5 meter sample line.)

Wide dynamic measurement range.

Large selection of NOx analyzers (vacuum/atmospheric, hot/cold, and wet/dry/switchable between wet and dry) meet diverse testing requirements.

Super-low emission (SLE) analyzers provide 2% of point accuracy down to 0.1 ppm for HC, NOx, and CH₄ and down to 1 ppm for CO.

Heated accessories for engine testing assure accurate results and flexibility in test-cell configuration.

Main Control Unit provides easy touch-screen operation and maximum functionality.

Links to a host computer via LAN, GP-IB, or AK RS-232/LAN.

Includes three levels of user log-ons for system security.
