Brand Name: TAQU
Model Number: T28
Place of Origin: China
Summary
T28 series carbon dioxide sensors are applied to the detection and control of CO2 concentration, which can monitor ventilation system, effectively reduce energy consumption and meet the requirements of relevant building ventilation, energy saving and related standards. In garages or motor vehicle maintenance and operation workshops, the start-stop control of ventilation system should be carried out according to the use situation, or the automatic operation control should be carried out according to CO2 concentration.
T28 series carbon dioxide sensors can be used in various intelligent buildings, HVAC systems, such as airports, stations, subway stations, pharmaceutical factories, museums, intelligent buildings and gymnasiums.Infrared principle gas sensor is used in the product. There are many kinds of output signals to choose. Pipeline installation equipped with conductive PC or stainless steel probes can meet the measurement requirements of different measuring environments and various high precision and high stability.
