RAD10E 10-Plate Solar Radiation Shield for EE181 with U-bolt

The RAD10E, manufactured by MetSpec, is attached to a Campbell Scientific crossarm or mast. The RAD10E uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. This shield also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C (~75°F)) and low wind speeds (< 2 m s-1 (~4.5 mph)), giving a better measurement. Learn More


TDR200 Time-Domain Reflectometer

The TDR200 Time-Domain Reflectometer is the core of the Campbell Scientific time-domain reflectometry (TDR) system. TDR systems accurately determine soil volumetric water content, soil bulk electrical conductivity, rock mass deformation, or a user-specific time-domain measurement. One Campbell Scientific datalogger can control multiple TDR200 reflectometers. Learn More

SR50AT-L Sonic Ranging Sensor with Temperature Sensor

The SR50AT-L is a sonic ranging sensor with an integrated external temperature probe. Sonic ranging sensors determine distance by emitting an ultrasonic pulse and then measuring the elapsed time between the emission and return of the pulse. The temperature probe allows the SR50AT series to output temperature-corrected values (speed of sound varies with temperature). Note: Campbell Scientific recommends model SR50AT-316SS-L for marine environments. Learn More


SR50AH-L Heated Sonic Ranging Sensor

The SR50AH heated sonic ranging sensor provides a non-contact method for determining snow or water depth. It determines depth by emitting an ultrasonic pulse and then measuring the elapsed time between the emission and return of the pulse. An air temperature measurement is required to correct for variations of the speed of sound in air. The SR50AH includes an integrated heater that prevents ice and rime... Learn More


SR50ATH-L Sonic Ranging Sensor with Heater and Temperature Sensor

The SR50ATH is a sonic ranging sensor with an integrated external temperature probe and heater. Sonic ranging sensors determine distance by emitting an ultrasonic pulse and then measuring the elapsed time between the emission and return of the pulse. The temperature probe allows the SR50AT series to output temperature-corrected values (speed of sound varies with temperature). The integrated heater prevents ice and rime from coating the transducer. Note:... Learn More


SR50A-316SS-L Stainless-Steel Sonic Ranging Sensor for Marine Environments

The SR50A-316SS is a rugged acoustic sensor for measuring the distance from the sensor to a target. The SR50A-316SS has a 316L marine-grade stainless-steel chassis and Parylene-coated transducer that allow the sensor to be used in marine or other corrosive environments. It is typically used to measure snow or water depth, but it is well-suited for other uses. Because the speed of sound in air varies with... Learn More
