For High Velocity VAV systems, this is a great purchase.
Extremely useful for pneumatic VAV diagnostics. For many VAV damper systems knowing the proper velocity across reheat electric coils is vital to an efficient temperature rise and prevent temperature limit cycling. If a system is 20 ft in the air and the Pneumatic thermostat requires calibration the adjustments can be viewed while staying near the the control. I currently own the Fluke 922 and this 923 model allows diagnosis while staying below the system. I'll use the 922 near the damper system and use the wireless 923 to monitor calibrations.
