Series 477 Handheld Digital Manometers are packed with features you need to make low pressure measurement and recording faster, easier and more accurate than ever. Now you can instantly select from up to nine popular pressure units without having to waste time with tedious conversions. Plus, a versatile non-volatile memory function enables storage of up to 20 readings - perfect for HVAC technicians making Pilot tube traverses of airflow through ducts. A display HOLD key temporarily freezes the current value for situations where pressure fluctuates. To protect against overpressure, both usual and audible alarms are included. Audible alarm also sounds to indicate a value has been stored in memory.
