The Certifier™ Plus High Flow Module 4081 is one half of the Certifier™ Plus Test Systems 4080-S and 4080-F and communicates measurements to the Interface Display Module. The high flow module contains calibrated sensors for bi-directional flows, barometric pressure (375 to 1200 mmHg), low pressure (-25 to 150 cm H2O), high pressure (-10 to 150 psig), and temperature (5 to 40°C ). The high flow module also includes a 3.5 mm mono audio jack capable of accepting an oxygen sensor (from the optional 4073 kit) to measure oxygen concentrations.
A flow module (Certifier™ Plus High Flow Module 4081 or Certifier™ Plus Low Flow Module 4082) must be used in conjunction with either the Certifier™ Plus Display Interface Module 4089 or Certifier™ FA+ Interface Module 4088 (discontinued). A Certifier™ Module 4081 may also be purchased individually (not as part of a Certifier™ Test System 4080-S or 4080-F) to replace an existing flow module or to have an additional flow module to maintain up-time if other flow modules are unavailable.
