Vehicle Emissions Monitoring

Why measure vehicle emissions?

By monitoring vehicle emissions, owners and drivers can play a hands-on role in reducing pollution from the vehicles and intern improving fuel consumption. There are distinct links between regular servicing, maintenance and improved emissions performance of vehicles, by monitoring the emissions of fleet vehicles (forklifts, trucks etc.), these links can be identified.

► Reducing pollution;

► Improving engine efficiency;

► Reducing fuel consumption;

► Reducing risk to staff.

What to know before purchasing?

Before purchasing a portable analyser, it is useful to know the environment and parameters needed to be measured. Know the following and save time and money:

► Temperature at which the gas is to be measured;

► Maximum gas concentrations;

► Accuracy required;

► Reason for monitoring (OH&S, efficiency etc.);

► Other gases present;

► Financial benefit and equipment budget.

Which gases to monitor?

The most commonly measured gases for vehicle emissions are O2, CO, CO2, and HC's. This will change as per the reason for monitoring and may include other gases which may be useful for efficiency and fuel consumption testing.

Gases handled by either the Testo 335 or 350

► O2 Oxygen 0..25% vol

► CO Carbon Monoxide 0..10,000 ppm

► CO2 Carbon Dioxide 0..50% vol

► NO Nitrogen Oxide 0..3,000 ppm

► NO2 Nitrogen Dioxide 0..500 ppm

► SO2 Sulfur Dioxide 0..5,000 ppm

► H2S Hydrogen Sulfide 0..300 ppm

► HC Hydrocarbons 0.01..4% LEL

Note:

1. HC stated above covers Methane, Propane & Butane.

2. NOx is the general term of both NO and NO2 as a combined reading.

Which instrument to use?

There are two portable instruments that may suit the needs of vehicle emissions monitoring, depending upon the required gases and options.

Testo 335

► Up to 3 gases at one time (O2,CO, CO2, NO, NO2, SO2)

► Temperature and differential pressure

► Data logging of up to 2 hours

► Dilution x2 (optional) - enables larger measuring range

Testo 350

► Up to 6 gases (O2,CO, CO2, NO, NO2, SO2, H2S, HC)

► Temperature and differential pressure

► Data logging (250,000 Readings)

► Temperature and differential pressure

► Dilution - enables larger measuring range

► Built-in printer
