Custom Test Hardware

Not only do we perform field and laboratory testing services, but we have developed custom testing systems and probes that extract the most precise flow-related measurements available while remaining simple to operate.  Our in-house wind tunnel (which meets EPA requirements for compliance testing) is used to calibrate velocity probes .

Advanced Coal Flow Measurement System (ACFM)

The ACFM system brings a state-of-the-art solution to the difficulty of performing reliable, efficient, and accurate primary air and pulverized coal flow measurements.

  • Electronic data acquisition
  • Automated test reports
  • Computer controlled isokinetic extraction rate
  • Fast, efficient & repeatable testing with minimum test crew size

3D Duct Testing System (3DDAS)

The 3DDAS sets a new standard for volumetric flow measurement systems.  Fully compliant with EPA Methods 2, 2F, 2G & 2H, it is for use in Stack/RATA testing, fan outlet ducts, mill inlet ducts, and all general ductwork (both round and rectangular).

  • Precise and repeatable results
  • Speeds up 3D testing process
  • Clear & simple touch screen navigation
  • Automatically generates test reports in spreadsheet format


We design and manufacture Air Flow Tunnels that meet the industry standard test specifications of ANSI/AMCA 210 and ASHRAE 51. These tunnels allow highly accurate flow measurement, automated data logging, and immediate reporting. Tunnel sizes range from small for leakage testing to king-sized for large fan testing.

  • Flow measurement
  • RPM aux imputs
  • Fant volts/amps
  • System pressure drop

Online Video Inspections

Ever wonder what is happening inside your plant at load?  We can take a look!  We offer online inspections of your facility via a remote inspection camera.  Results include report and narrated video.

  • Up to 1400ºF
  • Probe configurable from 4 ft. to 20 ft. long
  • Up to 20 ft. viewing range
  • Only requires compressed air & 120V AC Power

Custom Probe Fabrication

We provide fabrication and calibration services for all types of pressure style probes. Each is hand crafted in our on-site laboratory/fabrication facility by our highly skilled staff. Our technicians and engineers work together closely to produce both standard configurations and custom probes for complicated or unique applications.  Available probes include:
