Our Products
We offer a complete product range of VOC-8 : Indoor Air Quality Transmitters
The VOC-8. air quality sensors measure the concentration of multiple gasesand odorous substances in the air with constant output. These substances, forexample, may be tobacco smoke, kitchen vapors, human odors and unpleasantsmells. In conjunction with a control device, it controls the fresh air supplyaccording to the quality of the air in the room; as a result, energy savingscan be made. In combination with a measurement device, it provides anindication of air quality in the room
