Zephyr IIt
Differential Pressure Meters
(Auto-Zeroing)
Differential pressure (∆P) measurement
is a crucial parameter for determining
pollutant pathways for IAQ and worker
exposure applications. It is also a key HVAC parameter in
commercial and institutional buildings and in manufacturing
plants, among many other important applications.
Each Zephyr II instrument includes a built-in, autozeroing micro-manometer and ‘K’-type thermocouple
input for measuring differential pressure, static
pressure and temperature. The auto-zeroing feature
allows for highly accurate differential pressure
logging over time. With a pitot tube, the Zephyr
provides direct air velocity readings and volume
flow rate (VFR). Zephyrs may also be fitted with a
telescoping 3-function probe (model 2300 AHTS) to
measure humidity, temperature
and (hotwire) airspeed/VFR.
The display and menu
system provide step-bystep guides for each
operation. This ensures
minimal user training is
required. Volumetric
flow is calculated by
simply entering the size
of the duct and the
instrument performs the
necessary calculation.
This meter offers
excellent low-end ∆P
sensitivity and (due
to the auto-zeroing
capacity) exceptional
stability near zero (to 0.5Pa, 0.002 in.H2O). However, it also
provides a very wide ∆P measurement range to +/-6000Pa
(+/-25 in.H2O).
