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...

The CS620 is the sensor used in a HydroSense System. The Hydrosense system combines a compact, handheld display and a sophisticated soil water sensing probe in a portable package to provide quick and reliable soil water ...

The CS625-L measures the volumetric water content of porous media using time-domain measurement methods that are sensitive to dielectric permittivity. The CS625 sensor is similar to our CS616 probe but is for the CR200-s...

The CS616 Water Content Reflectometer measures the volumetric water content from 0% to saturation. It uses time-domain measurement methods, but a reflectometer (cable tester) such as the TDR100 is not required. The probe...

The TCAV-L typically provides the average temperature of the top 6 to 8 centimeters of soil. The probe parallels four type E thermocouples together into one, 24-gauge wire. Each member of a thermocouple pair is buried at...

The 109SS consists of a thermistor encased in a sheath made from grade 316 stainless steel. The rugged stainless-steel sheath protects the thermistor allowing the 109SS to be buried or submerged in harsh, corrosive envir...
