Particle nubmer counter NP01

Instruments for measuring vehicle exhaust particulate number emissions. NP 01 is a particle counter working in the dimensional range between 23 and 200 nm using a DC sensor. NP 01 integrates a touch screen display for a fast and easy management by end user and a WiFi interface for communicating to the visualization software. NP 01 was developed respecting technical specifications requested by Dutch N-PTI regulation and German PTB-A 12.16. Technology DC Response time 95% < 15 sec Measuring range 5.000 – 5.000.000 #/cm3 Error (absolute) 25.000 #/cm3 Error (relative) 25% Particle size 23 -200 nm Resolution 1.000 #/cm3 Interfaces WiFi, US
