Many times scientists and researchers spend more time setting up equipment and instrumentation for their experiments than conducting actual experiments to gather important data. This holds true for flow meters and controllers to measure and control gases to experiments. Some flow meters are very cumbersome with no display, can only measure one gas, low value for price, and limited application flexibility.  And if you need application […]
