Measure
wind speed accurately
with the Model PWM1 Pocket Wind Meter. The rotating vane anemometer
is constructed with a light weight, anodized aluminum impeller
which spins on high precision jewel bearings. The impeller assembly
is easily replaceable in the event of damage or wear. Wind speed,
average wind speed and maximum wind speed can quickly be viewed
on the 2-1/2 digit LCD display in user selectable measuring units.
The unit also features automatic shut-off 30 minutes after the
last key is pressed. The compact, rugged anemometer is waterproof
and rated NEMA 6 (IP67). The unit will float if accidentally
dropped in water. Model PWM1 includes a slip-on hard case to
protect the display and impeller, 20" (0.5 m) lanyard, and instruction
manual.
Measure wind speed, temperature and wind
chill with the Model PWM2 Pocket Thermo-Anemometer. The
rotating vane anemometer is constructed with a light weight,
anodized aluminum impeller which spins on high precision jewel
bearings. The impeller assembly is easily replaceable in the
event of damage or wear. Wind speed, average wind speed, maximum
wind speed, temperature, and wind chill can quickly be viewed
on the 3-1/2 digit LCD in user selectable measuring units.
The unit also features automatic shut-off 30 minutes after
the last key is pressed. The compact, rugged anemometer is
waterproof and rated NEMA 6 (IP67). The unit will float if
accidentally dropped in water. Model PWM2 includes a slip-on
hard case to protect the display and impeller, 20" (0.5 m)
lanyard, and instruction manual.
Measure wind speed, temperature, wind chill,
heat index, and dew point with the Model PWM3 Pocket Weather
Meter. Measuring modes and display units can be changed at
any time. All functions are controlled with two buttons. The
PWM3 displays maximum, average, and current wind speed in knots,
meters per second, kilometers per hour, miles per hour, feet
per minute, and Beaufort scales. Quickly select temperature
measurement in °F or °C. The unit also features automatic
shut-off 30 minutes after the last key is pressed. The compact,
rugged weather meter is waterproof and rated NEMA 6 (IP67).
The unit will float if accidentally dropped in water. Model
PWM3 includes a slip-on hard case to protect the display and
impeller, 20" (0.5 m) lanyard, and instruction manual. Dimensional
