Traceable Calibration Systems
Chinook Engineering, IML's research and development division, manufactures the patented Streamline™ Flow Transfer Standard and Streamline Pro™ MultiCal™ System. These high performance fluid flow meters are used extensively in air quality measurements. Due to its superior and consistent performance, the Streamline™ FTS has become the "standard" flow meter in the ambient air quality measurements industry. The Streamline Pro™ ultiCal™ System simplifies measurements while also providing traceable temperature and barometric pressure measurements.
Streamline™ and Streamline Pro™ systems are sold exclusively by Rupprecht & Patashnick Co., Inc. Chinook Engineering provides all service and technical support for the Streamline™ and Streamline Pro™ systems.
Metrology -NIST Traceable Calibrations
Chinook operates an NIST – traceable calibration/certification facility to provide quality assurance (QA) support for the fundamental measurements related to obtaining air quality concentrations. Parameters which can be certified are:
| |
Air flow rate: |
50 cc/min – 22 lpm, and 8 – 85 cfm
(appx. 250 –2500 lpm) |
| |
Manometry: |
0.01 – 25 “ H2O, other by special setup |
| |
Barometry: |
fractions – 1.2 atmospheres |
| |
Thermometry: |
-40 – +80 °C |
|
