The Model 8339 Laser Ceilometer measures cloud height and thickness, in addition to vertical visibility.  Unlike other ceilometers, the Model 8339 detects up to four cloud layers simultaneously to a distance of 25,000 vertical feet. Its precision makes it ideal for applications requiring the highest level of performance and reliability, such as aviation and meteorological studies.

The Model 8340 Laser Ceilometer uses a design similar to that of the 8339 however, with the addition of a more powerful laser and state-of-the-art firmware, the Model 8340 accurately reads cloud height, density, and vertical visibility to a distance of 40,000 vertical feet.

The 8364 Dual Technology Visibility Sensor measures transparency of the atmosphere and calculates its extension coefficient and meteorological optical range (MOR) values.  Using both direct attenuation and forward scatter technologies the 8364 can measure airborne particle sizes once available only from a transmissometer while having the reliability and cost effectiveness of a forward scatter visibility sensor. Its precision makes it ideal for applications requiring the highest in performance and reliability, such as aviation and meteorological studies.

The 8365 Dual Technology Visibility Sensor measures transparency of the atmosphere and calculates its extension coefficient and meteorological optical range (MOR) values. Using both direct attenuation and forward scatter technologies, the 8365 can measure airborne particle sizes once available only from a transmissometer, while having the reliability and cost-effectiveness of a forward scatter visibility sensor. Its precision makes it ideal for applications requiring the highest in performance and reliability, such as aviation and meteorological studies.

The Model 6500 Thunderstorm Detector, capable of detecting electrical discharges associated with thunderstorms up to 250 miles and more from the sensor. The Model 6500 is a passive sensor that listens for electromagnetic signals with a receiving antenna. There is no transmitter, and therefore no harmful transmissions.

The 6011 Series Tipping Bucket Rain & Snow Gauges are standard, precision instruments for measuring rainfall volume and/or rate.  Rain enters the gauges through a large funnel, the rim of which is protected by a metal ring to prevent distortion.  Collected water passes through a debris-filtering screen and is funneled into one of the two tipping buckets inside the gauge.  The bucket tips when a given amount of water has been collected; the amount of which is determined by gauge calibration. As the bucket tips, it causes a 0.1 second switch closure.  The tip also brings a second bucket into position under the funnel, ready to fill and repeat the cycle.  After the rain water is measured, it drains out through tubes in the base of the gauge.  These drain holes are covered by screens to prevent insect entry. Various models in the 6011 series offer data collection in either standard or metric units.

The 6021 series Electrically Heated Rain & Snow Gauges are available for areas where snow or freezing rain may occur.  These gauges operate in the same manor as the 6011 series gauges, but they are equipped with 4 separate heaters to ensure continuous operation even in extreme temperatures. 

The Model 6498 is an infrared forward scatter present weather/visibility sensor designed for the varied applications of automatic weather stations. This unit was engineered to measure environmental variables in even the harshest conditions. The sensor’s all-metal housing will provide years of uninterrupted weather monitoring while the self-regulating design minimizes maintenance by extending time between calibrations. The Model 6498 is capable of self-diagnosing dirty lenses and will indicate when lenses are contaminated and need to be cleaned.

The FAA certified Model 6490 Present Weather Sensor optically measures precipitation induced scintillation and applies algorithms to automatically determine the precipitation occurrence, type, and rate.  This sensor is vastly superior to traditional type sensors, and offers the reliability and proven performance you need.

The FAA certified, Model 6495 Freezing Rain Sensor uses an ultrasonic axially vibrating probe to detect the presence of icing conditions.  The vibrating frequency of the probe decreases with the accumulation of ice, frost, or wet snow.  After ice has accumulated on the probe to a predetermined thickness, the AWOS DCP instructs the sensor to turn on it`s internal heaters to deice the probe.
