APCA-370 Ambient Carbon Dioxide CO2 monitor/analyser

Category: Tags: , , ,

The APCA-370 is a device for continuous CO2 monitoring in ambient air.

It uses cross modulation type non-dispersive infrared (NDIR) absorption method. This method employes one cell and one light source for both sample gas and reference gas what allows precise measurement without generation of zero-drift. Due to precise measurement and long term stability in continuous monitoring as well as its minimal maintenance requirements, this method has been a preferred method for monitoring the atmospheric pollution.

Features:

  • High precision and accuracy in long term
  • Exceptionally low drift by a combination of cross flow modulation and infrared-absorption technology
  • No need for adjustment by optical alignment
  • HORIBA’s unique internal reference gas purifier*, which generates CO2-free zero gas and enhances analyzer performance
