  • Internal rechargeable battery and built-in data recorder
  • Measures up to 5 gases: HC, CO, CO2, O2, and NOx
  • Calculates AFR and Lambda and measures RPM
  • Multi-language LCD display
  • Fast warm up: less than 30 seconds

Connect the HM5000 to your vehicle's exhaust while you drive and in less than a second you'll see the composition of the exhaust gas. You'll know exactly how much Hydrocarbons (HC), Carbon Monoxide (CO), Carbon Dioxide (CO2), Oxygen (O2), and Oxides of Nitrogen (NOx) your vehicle is emitting.

You not only get instantaneous readings of up to 5 gases, you'll also get Air to Fuel (AFR) Ratio, Grams Per Mile (GPM) and Lambda which will help you in tuning that ever so tricky carburetor or injection system. The HM5000 can also measure and record your vehicle's engine speed along with all five gases. The combination of 5 gases and Tach will give you all you need to tune or troubleshoot your engine at various RPM's.

HM5000 interfaces to a PC or a PDA for complete control, display, and graphing capability. With its analog outputs, the HM5000 can be connected to a data acquisition system or run analog gauges.

You can even record all the data in the HM5000 while you're on a road test or taking laps around the track. When you return, just connect the HM5000 to a PC and download a history of your test drive for analysis.

No need to spend a fortune on a dyno to simulate road conditions; run that engine in the REAL world. Get better results with less investment. Now that's a win-win!


  • Perform road testing on the go
  • Detect fuel or emission related problems
  • Verify carburetor mixture
  • Measure catalytic converter performance
  • Find vacuum and exhaust leaks
  • Check for smog
  • Check PVC system
  • Measure engine RPM for 2 & 4 stroke or rotary engines
  • Adjust fuel injection or carburetor mixture

Compare the HM5000 to the Competition


  • Measures all 5 gases
  • Multi-language display (English, Spanish, and Arabic)
  • Completely self-contained
  • Has a 2% full-scale accuracy and 2-second response time
  • Internal water separator and purge pump that continuously removes water from the exhaust


  • Most calculate or guesstimate gases
  • Box of attachments that feel like a tote-along suitcase
  • Only 5% accuracy and 16-20 seconds response time
  • Uses water traps, which require constant service

Five gases, AFR, RPM, Lambda, data-record, and competition-busting prices, puts the HM5000 on top!
