TESTO Differential pressure manometers, 512 Owner's Manual
Testo Differential pressure manometers, 512, are compact digital pressure gauges with temperature compensation. Ideal for HVAC systems, they measure positive, negative, and differential pressure of non-aggressive gases. The testo 512-1 model also measures flow velocity using a Pitot tube. Measuring ranges vary by model (up to 200 hPa for 512-1 and up to 2000 hPa for 512-2).
