| The AXD550 MicroManometer is a compact portable digital instrument. Using microprocessor-based electronics, the AXD550 measures, records and stores differential pressure, static pressure and air velocity readings for HVAC, industrial and plant maintenance applications. The AXD550 is easy to use. A zeroing feature is available at the push of a button. It is completely position-insensitive, and is small enough to fit easily in a pocket, leaving the user's hands free to reach difficult locations to take pressure readings. The AXD550 feature a high contrast LCD. Memory contents can be reviewed using a unique ¡®page & line¡¯ display. With a push of a button the user can store 100 velocity, pressure or volume readings. Results can be downloaded to a computer using the integral RS232 port. The AXD550 allows the user to measure negative pressures without switching hoses and offers correction factor menu options to compensate for changing environmental conditions. |
