Differential
pressure is a crucial parameter for monitoring Indoor Air Quality (IAQ) and is
a key measurement for HVAC servicing and setup. The
Zephyr II micromanometers are designed to measure differential pressure, static
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 over time.
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.
