A great number of different gases and vapors can be measured by the short-term Dräger-Tubes®. These tubes are used e.g. for the determination of concentration peaks, the measurement of exposures in the inhalation area, the determination of possible leakages as well as for the analysis of air in sewers, shafts, tanks or other confined spaces.

Measurement strategy for clearance as per OSHA-PEL:Pre-test with Dräger X-am® 7000 (PID) at a rate of 0,51 $ per test, whereby approximately 20% of the measurements were followed by a selective measurement of benzene at a rate of 6,89 $ per tube measurement Pitot Tubes Accurately Measuring AirflowAccurate measurement requires density correction and a careful traverse. Because the accuracy is dictated by the pressure measurement device attached to the Pitot tube, there are often more economical ways (hot wire and vane) to measure airflow in low flow applications. For high flow or high temperature applications the Pitot tube is ideal.
PYREX® VISTA volumetric flasks provide precise volume measurement. The necks are tooled for Standard Taper glass stoppers. The graduation line is sharp and permanent and large blue block letters make the inscription easy to read. The 1 mL and 2 mL sizes are test tube shaped. These Class A RadiolaGuy :Testing Vacuum TubesAug 04, 2017 · New tubes (just like used ones) will vary considerably in their Mutual Conductance (measured in micromhos) or Gm (for short). Test results will vary depending on the type and brand of tube checker. Emission type checkers will only measure emission and this reading is very unreliable and will vary significantly with various tube tester models. When
