Skywatch Xplorer 4
Wind Meter & Portable Weather Station
Model:
xplorer4
SKU: DSD465960
JDC's SKYWATCH Xplorer series was launched in 2004, and has proven to
be one of the most exciting lines of windmeters yet! Packed with
features essential to monitoring the environment, the Xplorer series
breaks price barriers and is simple to use.
Designed for consumer and professional use, the Xplorer does not include
complicated and seldom-used features such as downloading and storing.
Press one button, and instant readings are at your fingertips.
Designed in Switzerland and built to our demanding specifications,
the SKYWATCH Xplorer series is engineered to provide a lifetime of
accurate and dependable use.
Skywatch Xplorer Series Measure:
Wind Speed - current, maximum
Wind Direction - electronic compass (Xplorers 3 & 4)
Ambient Temperature - current, windchill, maximum, minimum, water (Xplorers
2, 3, 4)
Barometric Air Pressure - absolute, relative, maximum, minimum(Xplorer
4)
Altitude - maximum, minimum(Xplorer 4)
Details:
WINDSPEED:
Balanced impeller is integrated into wind meter. The impeller is
magnetized, producing a magnetic field when rotating which is measured
internally
Damage to the impeller is unlikely due to the small opening, but repair
can be performed
TEMPERATURE:
Internal thermometer is attached to the stainless steel back.
Temperature adjusts quickly, although drastic temperature changes may
require several minutes for accuracy.
Temperature is read quickly by touching the back to an object of the
same temperature
Water temperature is read quickly by submerging the unit briefly
DIGITAL COMPASS:
Designed to be used in vertical position. Will display windspeed and
compass simultaneously
Electronic calibration before use ensures absolute precision (easy
process). Calibration is essential for proper use.
Accurate wind direction can be found in this way - we introduced this
feature in 2004
ALTITUDE:
Altitude is based on an initial set altitude and a change in air
pressure (this is true of ALL altimeters). Drastic air pressure
variance (weather front) will impact altitude readings (usually occurs
over 12+ hours). Several seconds is needed to adjust to new
altitude. The highest accuracy is achieved when the altitude is
properly set, a change in altitude is more than 10 feet, and several
seconds are allowed for adjustment.
For example, the Xplorer 4 may be moved from one level of a house to
another, and a change of 10 feet will be recorded (standard ceiling
height). Altitude and air pressure are measured on the same
sensor, and adjusting one will adjust the other
Altitude history is recorded every hour for the past 48 hours.

AIR PRESSURE:
Air pressure is read in either relative or absolute air pressure
Absolute air pressure is a precisely defined measurement, just like
temperature. Absolute air pressure is measured within .10 inHg,
and cannot be adjusted. Relative air pressure is the most common
unit used in the US.
Relative air pressure factors out the change in elevation,
essentially calculating the air pressure at sea level
Relative air pressure is adjusted to reflect current altitude.
Once the relative air pressure is set, if no changes to altitude occur
the accuracy is within 0.01 inHg.
The most important factor in changing weather is the change in air
pressure. Rising air pressure indicates better weather, falling
air pressure indicates worsening weather
With the air pressure history, one can accurately predict future
weather. Air pressure history is recorded every hour for the past
48 hours, although the past 6-12 hours is most important.
