The model 2001 VT is an all-digital ventilation controller designed to monitor the temperature and carbon dioxide level in the air and control the ventilation system according to ventilation requirements.
Adequate ventilation reduces temporary sickness, downtime and lost productivity.
Studies indicate that ventilation control based on C02 levels saves energy costs. Output Averaging Time 10 - 2500 sec. The AirTell is a portable sensor with digital display designed to monitor the temperature and carbon dioxide level of the air in spaces. It can be used for test and diagnostic purposes of ventilation systems. The sensor features a membrane covered sample chamber resulting in a stable, reliable and highly accurate carbon dioxide measurement.
