Low Mass Flow Calibration System...

   To support increasing requirements for documented accuracy at the process level, a transfer standard system combining high accuracy with portability and ease of use was needed. In response, in 1992, was introduced the molbloc™/molbox™ mass flow calibration system. Based on a new, patented, laminar flow element design, and applying today's modern measuring, mathematical modeling, data processing and manufacturing techniques, molbloc/molbox introduced a new level of performance in low mass flow standards. This new tool was rapidly and widely adopted by  those requiring reliable low mass flow measurements, in particular mass flow controller (MFC) users and manufacturers.

molbloc™/molbox™...

   molbloc™/molbox™ covers the flow range from less than 1 sccm to more than 100 slm with accuracy to ± 0.2% of reading in a variety of gases. A 1.5 second update rate makes real time measurement and test instrument adjustment with a true flow standard possible for the first time. Compact and readily transportable, molbloc/molbox can be operated locally from the full feature front panel or remotely by RS-232 or IEEE-488 interface using simple ASCII string commands.

Features:

  Founded on proven laws of gas behavior;  advanced pressure and temperature measurement technology; superior stability over time;outstanding rangeability; continuous, real time reading; multiple gas support; aAdvanced on board functions; standard communications interfaces; traceable accuracy supported by primary gravimetric standards; compass for molbox calibration assistance software; compact, rugged and transportable.
