The TSI Alnor AXD610 and AXD620 are easy to use, handheld digital micromanometers suitable for fast, accurate and reliable pressure and air velocity measurements. The AXD620 adds comprehensive functions that include volumetric flow rate calculation, programmable k-factors and data logging. Premium features make the TSI Alnor AXD610 and AXD620 micromanometers ideal for HVAC commissioning and troubleshooting, testing and balancing, pitot tube duct traverses, static pressure measurements, and differential pressure measurements.

AXD610 and AXD620 micromanometers measure differential and static pressure from -15 to +15 in. H2O (-3735 to +3735 Pa) with an accuracy of ±1% of reading ±0.005 in. H2O. When using a Pitot tube, air velocity measurements from 250 to 15,500 ft/min can be made with an accuracy of up to ±1.5%. The AXD620 micromanometer can also measure volumetric flow rates which are dependent upon duct size and k-factors. Additional features of the AXD620 include the ability to record data points in a duct traverse using the sampling function, data logging of 12,700+ samples with time and date stamp, LogDat2 downloading software and programmable K factors.
