Abstract:
A portable, calibratible gas detector includes a multi-position gas inflow limiting orifice. When this orifice is in a calibrating position, a source of calibrating gas can be activated to provide a quantity of gas that diffuses into ambient atmosphere flowing through the orifice. The calibration gas can then be sensed.
