Low-Pressure Differential Gauges with Digital Display
Measure small changes in air pressure with these hand-held gauges. They have a four-digit LCD display for easy reading of measurements. Gauges are commonly used to indicate clogged filters and to monitor fans and blowers.

Differential Pressure and Vacuum Gauges with Digital Display
Gauges have a four-digit LCD display for easy reading of measurements. Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements. They are also known as compound gauges.

Remote-Reading Airflow/Temperature Meters
A
B
C
With a probe on a cord, these meters access hard-to-reach places in duct. They display airflow and temperature simultaneously and can show airflow measurements on multiple scales, such as fpm, mph, and knots.
Use the RS-232 port to transmit data. For a USB connection, you'll need a USB adapter cable (sold separately).
Tube meters have a probe that telescopes to 3 ft. to reach into narrow openings.
