Product Details

The NPET 3795 helps you bring laboratory-grade particle counting to your worksite. The NPET features a sampling nozzle compatible with tailpipes, built-in 10:1 dilution, and a catalytic stripper to remove volatile particles. The instrument also has Ethernet connectivity, which enables data collection via a handheld tablet or laptop computer. Data can be collected in Official Measurement mode—which follows protocol for Swiss regulation SR 941.242—or in General mode, which allows customized measurements. Common applications include measuring particle emissions from non-road mobile machinery, stationary generators, and in-use buses.

Applications
