Alnor AXD620 Digital Handheld Micromanometer provides fast and accurate pressure readings and can also read velocity with volumetric flow user input duct sizes. Alnor AXD620 measures static and differential pressure and displays velocity through use of a Pitot tube. Made in the USA and includes a NIST Calibration Certificate.
- Calculates and displays velocity when using a Pitot tube
- Calculates volumetric flow rate in duct from velocity and user-input duct size and shape
- Records data points in duct traverse using sampling function
- Data logging with time and date stamp
- Programmable K factors
- Hard carrying case, 4 alkaline batteries, (2)1.2-m rubber tubes, static pressure tip, LogDat2 downloading software and USB cable operation, service manual and NIST calibration certificate

|Duct traverses with Pitot Tube
Pricey, but super accurate and you can use it for taking differential pressure on a bunch of units, like boiler flues and vent work. Great for anything in home contracting really.
Might seem old school to use a pitot tube to do my duct calculations, but damn, you cant argue with the accuracies of using them.
Data logging is pro
The data logging feature has a time and date stamp. Really nice to see the changes you made to the system show up in the data w/ time/date stamps to show the improvement.
While this unit is a little tricky to use at first. I purchased it for its amazing accuracy. You cant find this sort of accuracy in this price range.
It's a little extra work to put in the duct sizes but having the flow calculations is really helpful and makes it possible to use this lower cost meter versus an expensive capture hood or something like that.
