Zephyr II manometers measure differential pressure, static pressure,
volumetric pressure and temperature. The Zephyr II instruments
have a built-in auto-zeroing micro-manometer, a 'K'-type thermocouple
input and 2 BIN type connectors. Used with a pitot tube, the Zephyr
II provides direct air velocity readings. Optional probes such
as the telescoping 3-function “smart” probe for temperature, humidity
and air flow (hot wire) can be quickly connected. The auto-zeroing
feature allows for highly accurate differential pressure logging
Zephyr II instruments are designed
with the user in mind. The large rubber grip and membrane switch
pad ensure comfortable use and one-hand operation, even with
gloves on. The optional 3-function probe attaches to the side
of the instrument for one-handed operation.
The display and menu system provide
step-by-step guides for each operation ensuring minimal need
for user training. Data capture is standard and facilitates
duct traversing and direct volumetric flow calculations when
the size of the duct is entered.
Zephyr II instruments are stand-alone.
The Zephyr II+ with on-board memory can be interfaced to any
GrayWolf, WolfSense, PPC or LAP mobile PC based system
via a CF serial card (model ACC-SCDPC) providing the full capabilities
of GrayWolf's WolfSense software.
