Air Velocity Calibrator
TSI’s Model 8392 CERTIFIER® Air Velocity
Calibrator gives you reliable and convenient inhouse calibrations at a reasonable cost. You can
have the confidence of high accuracies over a wide
velocity range with the CERTIFIER. It enables you to
calibrate your probed air velocity meters or transducers at velocities as low as 30 ft/min (0.15 m/s) and as
high as 9000 ft/min (45 m/s) with typical accuracies
of ±1 percent of reading.
The CERTIFIER is ideal whenever frequent,
accurate, air velocity calibrations are required.
Having a CERTIFIER on site avoids the delays associated with sending the instrument to an outside
calibration facility. Calibrations can be performed
at your convenience as often as necessary.
The CERTIFIER comes with a TSI Model 8495
TRANSDUCER DISPLAY & MONITOR that will display actual air velocity. Entering a density correction factor automatically converts the velocity to
standard conditions. This allows the user to read
air velocity directly from the TRANSDUCER DISPLAY
& MONITOR instead of reading pressure and then
calculating velocity.
The Model
8392 CERTIFIER Air
Velocity Calibrator
provides a complete
system to meet all of
your calibration
needs. Standard
accessories furnished
with the system
include:
• Model 8495 TRANSDUCER DISPLAY & MONITOR
• MKS Pressure Transducer
• Fittings which accept 0.188 in. (4.8 mm)
through 0.625 in. (15.9 mm) diameter probes
(other sizes can be accommodated with the proper 1/2 NPT male compression fitting)
• Controller for setting fan speed
• Two nozzle plates for establishing low velocities
