• Testing and balancing
• Pitot tube duct traverses
• Static pressure measurements
• Differential pressure measurements
Rugged. Reliable. Professional.
Micromanometer
Models AXD610 and AXD620
The AXD610 is an easy to use, handheld digital
Micromanometer for fast, accurate and reliable pressure
measurement. It can also calculate velocity.
The AXD620 is a rugged, compact, comprehensive
Micromanometer that measures pressure, and calculates
velocity and volumetric flow rate. It can be used with Pitot
tubes to measure velocity and then calculate flow rates with
user–input duct size and shape. Premium features make it
ideal for HVAC, environmental safeguards, commissioning,
process control and system balancing.

1
Overpressure range = 190 in. H2O (7 psi, 360 mmHg, 48 kPa).
2
Pressure velocity measurements are not recommended below 1000 ft/min (5 m/s).
3
Accuracy is a function of converting pressure to velocity. Conversion accuracy improves when
actual pressure values increase.
