QBN-10 Type Portable Gas Detector
Product Description
QBN-10 Type Portable Gas Detector
Product Introduction:
QBN-10 type portable gas detector can be divided into pumping type and diffusion type, it can detect single gas or complex gas. With the characteristics of small cubage, high sensitivity, safety and reliability, it is widely used for concentration detection and alarm for flammable gas and poisonous gas in ship, petrochemical, fire control, mine etc.
Sampling pump is matched for pumping type gas detector, and the gas can be directly suctioned into sampling pump for detection. This type is suitable for closed space or mine gas.
Diffusion type can be located in detected condition for gas detection. Normally it needs to be taken along by man for detection, it is suitable for worker in hazardous area or the environment that man can access.
