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
