What we buy and sell
The instruments we look for.
The type of instrument matters more than its brand. These are the tools we seek out, not a list of what is in stock today.
Air velocity
Rotating vane anemometers, velometers and thermal or hot wire anemometers.
Hydronic testing
Hydronic manometers and clamp on ultrasonic flow meters for water flow and differential pressure.
Electrical and speed
True RMS multimeters, clamp ammeters, tachometers and strobes.
Temperature and humidity
Air temperature probes, immersion and contact thermometers, and humidity meters.
Sound and vibration
Sound level meters, octave analyzers, acoustic calibrators, vibration analyzers, transducers and vibration calibrators.
Shortridge, TSI Alnor and Evergreen are examples of names we look for in flow hoods. We also consider instruments from Fuji Electric, Retrotec, Testo, Fluke and other makers. The brand examples are never a limit on what we buy.
What a working kit needs
The right tool for the measurement.
NEBB and AABC focus on measurement functions and calibrated instruments, not a particular brand. Sound and vibration work may call for additional meters and calibrators. Each eBay listing states what is actually in the case and how it tested. Calibration documentation is included only when the listing says so.
- Base meter powers on and reads correctly
- Hood top, frame and fabric included when applicable
- Probes, tubing, hoses and cables accounted for
- Sound meters paired with an acoustic calibrator when included
- Vibration analyzers paired with a transducer and calibrator when included
- Missing parts and calibration documents stated in the listing
Every instrument graded. Every instrument guaranteed.
Graded 1 through 4. Tested. Model and serial number on the packing list. 100% Return Guarantee.
