Calibration should be performed at the same temperature, humidity and flow as the measurement. To connect to a ppbRAE or MiniRAE 2000, use Inlet Tube Adapter p/n 025-3002-000 according to the instructions on the reverse side. See Technical Notes 150, 172 and 178 for more details on use and how to connect other monitors. Storage Life: 3 years Temperature Range: -10 to +50°C Filtering efficiency for VOCs: a Measured with ppbRAE after 2-min. exposure. *This tube can not remove methane, ethane or ethylene. (Methane measured with and LEL sensor.) Cautions: • Single use only. • Attach tube shortly before zeroing to avoid loss of adsorption capacity. • Will not absorb CO; partially absorbs H2S. May not absorb some other inorganic compounds. File N:\Tubes\Data SheetsNew\VOC zeroing tube 025-2000-010
