  • Anemometer | PCE Instruments

    Anemometer. An anemometer measures wind speed. Indoors, an anemometer measures air speed, air velocity or air flow. The air flow rate in buildings is often measured in cubic feet per minute (CFM) using anemometers to assess the performance of heating, ventilation and air conditioning (HVAC) systems

  • In situ Rb–Sr dating by collision cell, multicollection ...

    The presence of oxygen contamination in the collision gas was monitored by Sr isotopic analysis of NIST SRM 610 normalised to Te-1. Because NIST SRM 610 has a relatively high Y/Sr ratio (∼1) compared to Te-1, the inaccuracy in 87 Sr 86 Sr should be a sensitive indicator for the presence of unresolved oxygen-based interferences, such as 89 Y ...
