Meteorology
The CR10X is used in long-term climatological monitoring,
meteorological research, and routine weather measurement
applications. Sensors the CR10X can measure include:
• cup, propeller, and
sonic anemometers
• tipping bucket and
weighing rain gages
• wind vanes
• evaporation pans
and lysimeters
• pyranometers
• ultrasonic distance
sensors
• thermistors, thermo-
couples, and RTDs
• capacitance and
strain gage baromet-
ric pressure sensors
• RH sensors
• cooled mirror
hygrometers
The CR10X can output data in your choice of units (e.g., wind
speed in miles per hour, meters per second, or knots). Standard
CR10X outputs include wind vector averaging, sigma, theta, his-
tograms, saturation vapor pressure, and vapor pressure from
wet/dry bulb temperatures.

Applications
The measurement precision, flexibility, long-term reliability, and economical price of the CR10X make it ideal for
scientific, commercial, and industrial applications.

quality, northern Oquirrh Mountains, Utah.
Air Quality
The CR10X can monitor and control gas analyzers, particle sam-
plers, and visibility sensors. The CR10X can also automatically
control calibration sequences and compute conditional averages
that exclude invalid data (e.g., data recorded during power fail-
ures or calibration intervals).
Industry
Vehicle Testing
The CR10X performs well in cold/hot temperature, high
altitude, off-highway, and cross-country tests. It can measure
temperature, fuel flow, velocity, acceleration, engine RPM,
force, displacement, and electrical system load. The CR10X
is often interfaced to a dashboard-mounted heads up display
for luminescent data display in real time.
HVAC Systems
The CR10X optimizes HVAC performance by monitoring and
controlling pumps, fans, and starter motors.
Process Control
Both product and assembly line status can be monitored
simultaneously, providing on-line quality control while mini-
mizing production down-time.
Agriculture and Agricultural Research
The versatility of the CR10X
allows measurement of agri-
cultural processes and equip-
ment in applications such as:
• plant water research
• canopy energy balance
• machinery performance
• plant pathology
• crop management
decisions
• food processing/storage
• frost prediction
• irrigation scheduling
• integrated pest manage-
ment
Soil Moisture
The CR10X is compatible with the following soil moisture mea-
surement technologies:
• Soil moisture blocks are inexpensive sensors that estimate
soil water potential.
• Matric water potential sensors also estimate soil water
potential but are more durable than soil moisture blocks.
• Time-Domain Reflectometry Systems (TDR) use a reflec-
tometer controlled by a CR10X to accurately measure soil
water content. Multiplexers allow sequential measurement of
a large number of probes by one reflectometer, reducing cost
per measurement.
• Self-contained water content reflectometers are sensors that
emit and measure a TDR pulse.
• Tensiometers measure the soil pore pressure of irrigated
soils and calculate soil moisture.
Typical agricultural research sites
integrate meteorological, soil, and
crop measurements.
