The LI200X Silicon Pyranometer is calibrated against an Eppley precision spectral pyranometer (PSP) to accurately measure sun-plus-sky radiation. The LI200X is used extensively in solar, agricultural, and meteorological ...

The CNR4 is a research-grade net radiometer. It measures the energy balance between incoming and outgoing radiation. It has a pyranometer and a pyrgeometer that face up, and another pair that face down. Both a thermistor...

The CS300 is a silicon pyranometer manufactured by Apogee Instruments. The range of the sensor is 300 to 1000 nanometers, which encompasses most of the shortwave radiation that reaches the Earth's surface. This senso...

The Watermark 200 provides a convenient method of estimating soil water potential between 0 and -2 bars (typically wetter, or irrigated soils) with a Campbell Scientific datalogger. The model 257 connects directly to the...

The 253 (also known as the Watermark 200) provides a convenient method of estimating soil water potential between 0 and -2 bars (typically wetter, or irrigated soils) with a Campbell Scientific datalogger. The 253 connec...

The 223-L estimates soil water potential from 0.1 to 10 bars. It is identical to the 227-L but configured for use with an AM16/32B multiplexer. When the 223-L is wet, electrical resistance is low. As the 223-L dries, res...

The 227 estimates soil water potential from 0.1 to 10 bars. When the 227-L is wet, electrical resistance is low. As the 227-L dries, resistance increases. Calibration of individual probes is recommended for accurate soil...

The 229-L Water Matric Potential Sensor measures soil water potential from 0.1 to 10 bars. The sensor consists of a heating element and thermocouple emplaced in epoxy in a hypodermic needle, which is encased in a porous ...

The EnviroSMART TM probes are manufactured by Sentek to provide soil water content profiles for irrigation scheduling or other water movement systems. The measurement range is oven dry to saturation. The probes measure s...

The SEN12512 is an EasyAG probe with an SDI-12 interface and a 50-cm length. This probe provides water content profiles for cultivated soils of good tilth—commonly found in vegetable production areas. It is unsuitable fo...
