Introduction; Technical Data - Swema SwemaFlow 125 Operating Instructions Manual

1. Introduction

Thank you for choosing a quality instrument from Swema.
SwemaFlow 125D measures air flow directly in l/s, m3/h or cfm
(when set to US units). The instrument is turned on and off with the
red button next to the display. When the instrument is turned on the
display shows first the firmware version then the voltage of the bat-
tery. After a few seconds the instrument is ready for measurement.
The instrument is automatically turned off after ten minutes.
The measuring equipment includes:
• Flow capture instrument
• Flow hood 300x300mm for exhaust flow (Some valves also supply)
• Carrying case, USB-cable, charger, Operating instructions
• Calibration certificate
