Top 10 Best Automotive Emission Analyzer of 2018 Review

We trust our cars to the mechanics and repairing specialists, but we never think what would have happened if they’d used different kind emission analyzer. Best OBD II scanners have increased “abilities” which provides extra and super fast problem diagnose and solving ways. And faster we can repair our car – faster we move forward. Sometimes the problem is not as grave as it seems at first look. Not every issue needs an electric welder or a cordless drill to be fixed. Sometimes the problem lies in the program of the car so just a diagnostic scanner is enough for repairs.

Typically, the analyzer is simply plugged into the connector, the vehicle is powered on (but not started), and you follow the simple menu on the display to retrieve any diagnostic codes saved to the onboard computer. These codes remain in memory until the problem is fixed or they are deliberately cleared.

Professional-level emission analyzers have much greater capabilities and require some training. Diagnostic technicians can do much more, such as perform specific bi-direction tests on running vehicles or connect to OEM-specific devices and controls to get feedback that won’t normally generate error codes.

Below, we have reviewed the top ten rated car emission analyzer that you can get your hands on today, along with detailed breakdowns of all the features and unique selling points of each OBD2 scan tools.

List of the most sold Automotive Emission Analyzers of 2018:

10. OTC UREA Diesel Exhaust Fluid (DEF) Refractometer

The Refractometer is a portable, precision, optical instrument used for measuring the Diesel Exhaust Fluid (DEF) concentration. When a liquid UREA sample is placed on the prism, the light passing through it is bent. The more concentrated the liquid, the more the light will bend. The Refractometer contains a reticle, or scale, that is enlarged through the eyepiece to measure this light. The values on the scale have been established to evaluate the DEF condition. EPA regulations require all diesel engines manufactured on or after January 1, 2010 to meet lowered NOx emissions standards. Most heavy duty engine (Class 7-8 trucks) manufacturers, have chosen to utilize SCR. This Includes Detroit Diesel (DD13, DD15, and DD16 models), Cummins (ISX line), PACCAR, and Volvo/Mack. SCR-equipped engines require the periodic addition of Diesel Exhaust Fluid (DEF, a urea solution) to enable the process. DEF is available in a bottle from most truck stops, and some have installed bulk DEF dispensers near the Diesel Fuel pumps. However, to ensure the proper operation of the SCR system, operators must ensure the DEF in their vehicle consists of a 32.5 percentage Urea/Water solution. It makes this a simple and quick process for an operator or technician. The information of the scale is: 0.5 percentage, line graduations 32.5 percentage, indicated scale 15-40 percentage, waterline, and 20 degree Celsius kit includes Refractometer, dropper, lens wipe cloth, instructions and quick guide, screwdriver, and case.
