Abstract
A portable detector is described for monitoring a gas in an atmosphere. The detector comprises a housing, at least one gas sensor carried by the housing, and electrical connectors carried by the housing for establishing electrical connections to a calibration apparatus and a microprocessor carried by the housing. The microprocessor controls the calibration apparatus via signals provided to microprocessor through the connectors to initiate the supply of calibration gas to the detector at a predetermined rate.
