摘要： A gas detecting and measuring device with which the gas or air to be examined is taken into a testing or measuring vessel such as an indicator tube by means of a feed system comprises an electrical motor driven suction pump and a pressure gauge connected thereto for pumping the gas to be tested through a connecting line. The connecting line includes the suction pump and a volume sensor provided in addition to a pressure sensor. The differential signal formed of the volume signal is converted in a characteristic generator to a desired pressure signal and the actual pressure signal from the pressure sensor is applied to a speed governor for the suction pump motor so that the suction pump is controlled to effect equalizing the actual pressure signal with a desired pressure signal.

摘要： The invention is directed to an arrangement for detecting gaseous components in air wherein an air pumping device pumps a sample quantity through the testing tube. The air pumping device includes a receiver for the testing tube and the charge in the testing tube is evaluated. The arrangement is improved in that the detection of different components with the corresponding testing tubes is conducted automatically in that the data characteristic for the measurement is automatically considered and processed to a display of the measured values. For this purpose, the testing tube is provided at its outer periphery with a machine-readable memory whose data is detected by a read unit when the testing tube is introduced into the receiver of the pumping device. The data from the machine-readable memory is conducted to an evaluation unit.

摘要： A method of testing a person's breath for the purpose of determining the alcohol content of the breath as an indication of the alcohol in the person's blood and using a carbon monoxide gas detector comprises treating the breathing air to oxidize the alcohol of the person's breath-air into carbon monoxide, collecting a predetermined quantity of the carbon monoxide with the treated breathing air and passing the treated quantity through the carbon monoxide detector to determine the quantity of carbon monoxide as an indicator of the alcohol content. The apparatus advantageously include a pyrolysis oven through which the breathing air is directed to oxidize the alcohol into carbon monoxide. The oven is connected to a collector to collect the predetermined quantity of the breathing air and the collector in turn is thereafter connected to a carbon monoxide testing tube. The carbon monoxide formed together with the treated breathing air is drawn from the collector by a suction pump and passed through the carbon monoxide testing tube.

摘要： A process for calibrating a gas metering instrument comprises flushing a test chamber with a flushing gas and subsequently filling it with a calibrating gas having a predetermined composition of carrier substance and carrier gas. The calibrating gas does not have to be carried and made available constantly in its predetermined composition. Thereby a reduction in the volume of the gas metering instrument is obtained. For this purpose, provisions are made so that a feed device introduces a specified amount of calibrating substance from a reservoir into the heat chamber, whereupon the calibrating substance mixes with the flushing gas in the test chamber to form the calibrating gas of predetermined composition. In addition, equipment is described for implementing the process of calibrating a gas metering instrument.

摘要： A testing device for measuring for nickel-aerosols includes a glass tube having breakable end tips for opening the tube for the passage of a test gas therethrough and a filling in the tube which includes a closed ampoule of hydrochloric acid, a filter layer for entrapping nickel particles of the gas being tested, a reaction layer of a material impregnated with a color reagent for nickel, a granular buffer layer and a second breakable ampoule of ammonia water arranged in the direction of flow of the test gas through the tube. The testing is carried out by breaking the first ampoule to release hydrochloric acid which flows through the filter and reacts with the nickel particles which pass to the reagent layer, subsequently breaking the second ampoule so that its contents will be directed into the granular buffer layer and in the reagent layer. The ammonia water in the second ampoule is directed into the buffer layer and then into the reagent layer to produce a color reaction in the reagent layer and the intensity of the discoloration produced is proportional to the amount of nickel filtered out of the test gas. This color is compared with a standard showing the color of reaction for various concentrations of nickel.
