Dwyer Instruments - Series 477: 477-2-FM Handheld DigitalManometer

Case Sold Separately

• New Low Pressure Ranges
• Instant Selection from up to Nine English/Metric Units
• Stores 40 Readings in Memory for Later Reference
• Measures Positive, Negative or Differential Pressures
• Large Easy-to-Read 0.4" LCD Display Includes Switchable Backlightfor Great Visibility
• Both Audible and Visual Overpressure Alarms
• Includes + and - Indicators plus Low Battery Warning
• Operates up to 100 Hours on a Single 9 Volt Battery

Series 477 Handheld Digital Manometers are packed withfeatures you need to make low pressure measurement and recordingfaster, easier and more accurate than ever. First, you caninstantly select from up to nine of the most widely used pressureunits without having to waste time and risk mistakes with tediousconversions. Next, a non-volatile memory function enables storageof up to 40 readings - perfect for HVAC technicians making Pitottube traverses of airflow readings across a duct. The Series 477 isFM approved intrinsically safe for hazardous locations, Class 1,Div. 1, Group A, B, C, D, T4.

When working in poorly lighted areas, just switch onthe handy backlight feature. It automatically shuts itself offafter 20 minutes to minimize battery drain. Electronic zeroingmeans you simply touch a single key to perfectly null out any minorpressure differences. A display HOLD key freezes the currentpressure for those all-too-common situations where readingsfluctuate. We even included an audible alarm to warn you ofoverpressure plus a visual alarm also confirms a value has beenstored, eliminating the need to observe display during a ducttraverse.

Dwyer Instruments - Series 477: 477-7-FM Handheld DigitalManometer

Case Sold Separately

• New Low Pressure Ranges
• Instant Selection from up to Nine English/Metric Units
• Stores 40 Readings in Memory for Later Reference
• Measures Positive, Negative or Differential Pressures
• Large Easy-to-Read 0.4" LCD Display Includes Switchable Backlightfor Great Visibility
• Both Audible and Visual Overpressure Alarms
• Includes + and - Indicators plus Low Battery Warning
• Operates up to 100 Hours on a Single 9 Volt Battery

Series 477 Handheld Digital Manometers are packed withfeatures you need to make low pressure measurement and recordingfaster, easier and more accurate than ever. First, you caninstantly select from up to nine of the most widely used pressureunits without having to waste time and risk mistakes with tediousconversions. Next, a non-volatile memory function enables storageof up to 40 readings - perfect for HVAC technicians making Pitottube traverses of airflow readings across a duct. The Series 477 isFM approved intrinsically safe for hazardous locations, Class 1,Div. 1, Group A, B, C, D, T4.

When working in poorly lighted areas, just switch onthe handy backlight feature. It automatically shuts itself offafter 20 minutes to minimize battery drain. Electronic zeroingmeans you simply touch a single key to perfectly null out any minorpressure differences. A display HOLD key freezes the currentpressure for those all-too-common situations where readingsfluctuate. We even included an audible alarm to warn you ofoverpressure plus a visual alarm also confirms a value has beenstored, eliminating the need to observe display during a ducttraverse.
