Description
NP 01
Measurement ofĀ particle number concentration (PN)Ā in the exhaust of motor vehicles has recently become really important in several European countries and it will be integrated in PTI legislation starting from Netherland, Belgium and Germany.
Charge-basedĀ sensing techniques for the examination of PN, likeĀ Diffusion Charging (DC), represents the main technology available for this type of check.
NP 01 is the first TEXA toolĀ of a new instrument generation developed and designed in orderĀ to measure particulate number concentration of motor vehicles emissions.
NP 01 is a particle counter working in the dimensional range between 23 and 200 nm using a DC sensor. NP 01 integrates aĀ touch screen displayĀ for a fast and easy management by end user and a WiFi interface for communicating to the visualization
software. NP 01 was developed respecting technicalĀ specifications requested by Dutch N-PTI regulation and German PTB-A 12.16.
