The 476A digital pressure gauge is suitable for laboratories or research institutions. It is a single pressure measurement with a range from -20 to 20 inches of water column and an accuracy of 1.5%. It is designed for HVAC engineering companies and can be used to adjust supply air pressure, calibrate and set pressure switches, adjust pressure reducers, system balance testing, etc. Made of aluminum alloy shell, sturdy and durable.
The 478A series digital differential pressure gauge can be used to measure positive pressure, negative pressure, or differential pressure. Its functions include: selectable engineering units, automatic zeroing, data retention, and peak valley value recording. Press and hold the Hold key to keep the current data displayed. The 478A has a zero point button that can be reset to zero at any time.
