Innovation Nilu - Model NDL4 - Data Logger - Brochure

NDL4 is the fourth generation of NILU data loggers and the accumulation of 35 years of experience in data logger development. NDL4 communicates digitally with the analyzer which makes it possible to collect both measurement data and status parameters. The status parameters give important information about the condition of the analyzer, such as gas flow rates, pump vacuum, etc. A number of commercially available ambient air quality analyzers are predefined in the data logger and can easily be activated. Using an external USB to RS232 converter or data switch, the data logger connects to the RS232 or Ethernet port on the analyzer. Analog sensors are logged using an external analog to digital converter.
