TEST APPARATUS FOR BREATH ALCOHOL ANALYZERS IN VARIABLE ATMOSPHERIC PRESSURE

摘要

PURPOSE: An apparatus for testing variable pressure of a breathalyzer is provided to perform tests at a certain place and to ensure test reliability. CONSTITUTION: An apparatus(1) for testing variable pressure of a breathalyzer comprises: a vacuum chamber(3) having a breathalyzer actuator with a solenoid switch; a pressure control device for controlling the inner pressure of the vacuum chamber; a connection pipe for injecting a standard gas into the breathalyzer; a controller(5) for operating the switch of the breathalyzer by controlling a solenoid switch; and a chamber door(15) having a transparent window(17) for the observation of alcohol concentration.
