DESCRIPTION
The UEI range of emission analyzers covering the models Auto 2-2, 4-2 and
AGA5000 has been designed to be used on petrol, LPG or CNG powered
engines*. All models measure carbon monoxide (CO), and unburnt
hydrocarbons (HC), with Oxygen (O2) and carbon dioxide (CO2) added to
four-gas models and nitric oxide (NO) included in five-gas variants. All four-
gas analyzers have an upgrade facility for Nitric Oxide (NO).
Using the measured parameters CO, HC, O2 and CO2, additional parameters
such as Lambda, Air to Fuel ratio and corrected carbon monoxide (COK) can
also be calculated and displayed.
All measured and calculated parameters can be printed on the optional
infrared printer or saved to the analyzer’s memory.
Each analyzer is supplied with an RS232 output enabling communication
between the analyzer and a PC. Using the optional auto software kit, live
emission data can be displayed, saved directly to the PC or printed to
produce high quality test reports. Data stored in the analyzer can also be
uploaded, diagnosed graphically and/or converted into spreadsheets for
service records.
All models are battery powered to give true portability in the workshop
environment. The battery can be charged with the supplied mains adaptor
or 12V cable.
* For diesel applications, HC measured in the exhaust gas is indicated in ppm
(parts per million) n-hexane.
