The Certifier™ Low Flow Module 4082 is sold as an accessory to the Certifier™ Plus Test System and communicates measurements to Certifier™ Interface Modules. The low flow module measures uni-directional flows and inhaled volumes of Air, O2, N2O, CO2, and N2 with greater accuracy at low flow rates than the high flow module. The Certifier™ Low Flow Module 4082 contains calibrated sensors for flow (0.01 to 20 slpm), barometric pressure (375 to 1500 mmHg), and temperature (5 to 40°C ).
A flow module (Certifier™ Low Flow Module 4082 or Certifier™ FA+ High Flow Module 4081) must be used in conjunction with either the Certifier™ Plus Interface Module 4089 or Certifier™ FA+ Interface Module 4088 (discontinued). A Certifier™ Kit must be purchased separately from the Certifier™ Plus Test System Kit 4080-S or 4080-F as an accessory item.
