Ametek / AEI CO2 Analyzer (CD-3A)

Infra-red type, fast response.




Photo shows both Ametek O2 and CO2 analyzers on VacuMed Metabolic Cart model MX-Ametek.


Introduction

The Model CD-3A Carbon Dioxide Analyzer provides a continuous and accurate measurement of gases containing up to 15% CO2. The Model CD-3A has the rapid response necessary for breath-by-breath analysis during respiration. It is also ideal for laboratory applications requiring high accuracy and sensitivity.



Features:

  • Wide range: 0 to 15% CO2
  • High accuracy and sensitivity
  • Rapid response - ideal for accurate breath-by breath measurement
  • End Tidal CO2 Display
  • Microprocessor controlled - reliable, low maintenance operation

The Gold Standard in laboratory carbon dioxide analysis
for over 20 years, worldwide.

Capabilities

A complete Model CD-3A consists of a sensor, readout/control unit, and cable. When the sample gas is passed through the sensor, a voltage that is a function of the carbon dioxide concentration of the gas is generated. This voltage is fed to the readout/control unit via a connecting cable.

The optional R-1 (Single Channel) or R-2 (Dual Channel) Flow Control Unit can be used to draw the sample through the sensor. Each flow control unit contains a pump, a needle valve, and a flowmeter for each channel. Other gas handling equipment can be used if preferred, such as VacuMed's low cost flow controller noted at the bottom of this page.
