Series 477AV Digital Manometers
Intrinsically Safe with ±0.5%
The Series 477AV portable digital
micromanometers (PDM) includes
11 meters with ranges from 0-200" H2O / 0-150 psi and measure positive,
negative or differential pressures. Users can select to display from
9 switchable pressure units: psid, inch H2O, mm H2O, inch Hg, mmHg,
kPa, Pa, bar, mbar. The Dwyer 477AV is FM approved Intrinsically Safe
for Hazardous Locations, Class 1, Div. 1, Group A, B, C, D, T4.
Sensing Solutions / Solomat Zephyr II+
Micromanometer with HVAC 3-Function Probe
Graywofl/Solomat Zephyr II+ Micromanometer with 3-function probe 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.
Testo 512-Series Portable Digital Manometers
Displays Pressure & Velocity
Testo 512 portable digital manometer series includes four different
versatile pressure and velocity meters. When connected to a Pitot
tube, the Testo 512 meters display 6 switchable pressure units: hPa/mbar,
mm H2O, mm Hg, psi, in H2O and in Hg; 2 switchable velocity units,
m/s and fpm; ±0.5 % full-scale value / ± 1 digit and
integral density compensation. Not intrinsically safe.
Pocket Pro 510 Micromanometer
Differential Pressure & Velocity
Testo 510 PocketPro portable digital micromanometer has a measurement
range of ±40" H2O, with air density compensation and a display
resolution of 0.01" H2O. User can select from 10 units of measurement:
hPa, mbar, Pa, mm H2O, mm Hg, in H2O, in Hg, psi. It will display air
velocity in fpm or m/s when used with an optional Pitot tube. A magnetic
back aids in hands free use. WolfSense software make it a very versatile
HVAC troubleshooting tool. Is not intrinsically safe.
521-526 Series Multifuction Micromanometers
The Testo 521-526
Series multifunction meter with built-in micromanometer is configured
for differential pressure measurements in the HVAC range of 0 to 40"
wg (0-100 hPa), e.g. pressure drops across filters or inspection of
fans or extraction equipment. The meter has nine user selectable display
pressure units: in H2O, mbar, hPa, bar, Pa, kPa, mm H2O, torr and
enhanced as additional probes such as temperature and humidity can
be connected to Testo 521-526 pressure meters via 2 user defined probe
