System Description The CO₂ system is a reliable and stable system that perform the CO₂ control in the chamber in the range from ambient value to 20% by volume (or more if needed). It is composed of a proportional valve, a CO₂ probe and a controller (integrated in the chamber’s controller with the PRO version). No air inlet is needed for this kind of CO₂ system. The CO₂ flow rate is approximately 0.2 m3/h with a pressure reducer of 0.5 bar. The consumption of CO₂ depends on the test condition and can’t be predicted in advance. The controller has a digital bright display at high contrast, with...

Extended alarm Optional: The device is equipped with a visual and audible alarm for CO2. There are two alarms available, one is a threshold alarm and the other is a maximum CO2 alarm that stops the CO2 input if the perceived value is high. The alarm is activated when the perceived CO2 exceeds the set point plus the alarm value or is below the set point minus the alarm value for a period of time greater than 15 minutes. Normal operating conditions: CO2_SP-ALRM1<CO2_PV<CO2_SP+ALRM1 • CO2_PV = CO2 value measured by the controller. The alarm is activated when the perceived CO2 exceeds the set alarm...
