3.1
Appropriate use
The EMA 200 is a portable, battery-powered digital pressure gauge for measuring
positive and negative differential pressures. At the heart of this precision instrument is
a pressure measurement capsule containing a membrane spring; the deflection of
this spring is then ascertained via an inductive measurement principle. Because it is
durable and easy-to-use, the EMA 200 lends itself well to maintenance work and
customer servicing for heating, air-conditioning and ventilation units, where it can be
used for monitoring filters, measuring fireplace drafts and wind pressure, etc.Its
precision and reproducibility also make the EMA 200 is highly suitable for use in
laboratory applications.
