• Engineering Units (8-selectable): Inches of H₂O @ 20°C, mm of H₂O @ 20°C, mm of Hg @ 0°C, Inches of Hg @ 0°C, kPa, mBar, Bar, PSI and user selectable.
• Media Compatibility: Non-isolated sensor for clean, dry, non-corrosive gases.
• Pressure Limits: (DN) units - 3 x F.S. on high side only or 200 PSI,whichever is less.
  (GN or AN) units - 3 x F.S. range or 200 PSI, whicheveris less.
• Accuracy: No temperature effect over the entire operating range 14F° to 122°F (-10C° to +50°C).
• Min/Max (M101 only): Displays the MIN and MAX pressures.
• Hold (M101 only): Freezes the pressure measurement on the display, however, the bar graph is still active.
• Ave (M101 only): Displays a continuous filtered average of the pressure measurements.
• Temp: Displays the internal ambient temperature of the M1 in °C or °F.
• Record Mode: The M1 can store up to 240 pressure measurements.
  • Automatic - the current value is automatically stored every 5 seconds, for up to 20 minutes.
  • Manual - the current value is stored every time theUnits key is pressed, up to 240 times.
• Backlight: A green backlight is user activated via the backlight key. A red backlight is automatically activated during an error/ over range condition.
• Auto Shutoff: To conserve battery life, the M1 will automatically power off after 20 minutes of keypad inactivity.
• Field Recalibration: M1 can be calibrated in the field for zero and span.
• Low Battery Indication: BAT icon is displayed when batteries require replacement. Approximately 2 hours of run time is provided on a low battery condition.
• Bar Graph: Horizontal bar for full scale pressure reference (0-100%)

Applications:

• Leak testing for low pressure gas systems
• Pressure drop monitoring across filters
• Monitoring vacuum on condensers or pumps
• Verification of CPAP or BIPAP systems for home or hospital settings
