Ambient gas detectors normally operate in a diffusion mode in many applications with the gas transported to the sensor by convection, wind and other means. In some instances, conditions warrant the use of an extractive, sample drawing type configuration: the environment may be too harsh for sensor installation, the sensor would be inaccessible for routine maintenance, the sample point is in a confined area such as a duct or exhaust. Under certain conditions, the sample drawing system provides opportunity to install the gas detector at an accessible location and the on-board integral pump continuously draws gas from the designated sample location. A specialized pump, designed for handling corrosive and hostile gases is utilized to provide optimum service in difficult industrial environments.
