APPARATUS FOR GRADUATING AND CALIBRATING INDICATORS OF PRE-EXPLOSIVE VAPOUR CONCENTRATIONS OF MULTICOMPONENT LIQUIDS IN AIR IN WORKING AREA

摘要

FIELD: physics. ^ SUBSTANCE: apparatus has a temperature metre (11), a liquid cryostat (2) with a thermostatting system (3) in which there is a static saturator (1). The saturator (1) is a thin-walled vessel connected to a working chamber (7). The vessel is partially filled with a multicomponent liquid stirred by a magnetic stirrer (9). The working chamber (7) is placed in a liquid thermostat (12) equipped with a thermostatting system (8) and a diffusion channel (5). The diffusion channel (5) is in form of a hollow cylinder consisting of three cylinder bushings built one into the other and fitted with a rotary valve (6) which separates the working chamber (7) from the saturator (1). ^ EFFECT: high accuracy of calibration. ^ 2 cl, 1 dwg
