DESCRIPTION
The 7460 Series Portable Analyzers are available in six versions for the simultaneous measurement of the
gases typically found in the exhaust from internal combustion engines. CO, CO2, and HC' s are detected by a dual-wavelength infra red detector. O2 and NOx ( as NO) are detected by customer-replaceable electrochemical sensors. If NO2 analysis is selected, this is also by electro-chemical sensor.
All detector outputs are displayed on separate front panel digital meters. Optional built in printer, datalogger and
4-20 ma recorder outputs are also available.
The 7460 Series Analyzers come complete with built in sampling pump, flow meter, automatic condensate
removal, filters, PTFE liquid block, 12 ft. ( 4m) sampling hose, and stainless steel probe. Also included are a
cigarette lighter socket and remote printer actuator button for printer based models.
