9687 Portable Flow Standard
NEW VERSION!
The New Model 9687 is an economical laboratory grade flow standard designed specifically for the calibration of Rotameters, thermal mass flowmeters and laminar flowmeters. This rugged portable device is built for use in the field or for in-house calibration facilities.
The 9687's unique touch screen reads information from three standards grade laminar flow elements to measure flow rate. We utilize laminar meters due to the fact that laminar flow elements are not subject to the kind of drift or instability exhibited by other flow devices.
This is the most accurate and stable system available today. The touch screen makes this also one of the easiest flow standards to read and utilize.
A source of clean dry air or nitrogen is allowed to pass through the device being calibrated and into the 9687. The gases pressure and temperature are measured and corrected to standard conditions. This feature eliminates the need for a temperature-controlled laboratory and makes use in the field possible.
