A device for determining the number of solid particles in car exhaust gases NP01
Determination of particulate matter (PN) concentration in exhaust gases has become very important
in several European countries, where it will become part of the mandatory annual technical
inspection. The Netherlands, Belgium and Germany are the first to introduce this measurement.
Measurement technology based on particle charge measurements, such as Diffusion Charge
(DC), is the most popular in this type of equipment.
NP 01 is the first TEXA designed and created device for the new generation of exhaust gases
for inspection. The NP1 solid particle counter operates in a particle size range of 23
up to 200 nm using a DC sensor.
The NP 01 has a built-in touch screen for fast and accurate control, as well as WiFi connection
with a display device (Computer or other smart device.)
The NP 01 was designed to be able to measure according to the Dutch N-PTI and
German PTB-A 12.26 standards.
