The HM-5000 automotive gas analyzer allows the measurement of four or five gas components in combustion exhaust. It is capable of determining volume concentrations of HC (Hydrocarbons), CO (Carbon Monoxide), CO2 (Carbon Dioxide), O2 (Oxygen) and optionally NOX (Nitric Oxide).
It can use these measurements to calculate the Air to Fuel Ration (AFR), Lambda (λ) and Grams per Mile (GPM) or Grams per Kilometer. Weighing less than 2 pounds, the HM-5000 is intended for use in a variety of indoor or outdoor environments.
Using the internal record feature, you can store data during a test drive and download the information to a PC or PDA when you return.
