Soil moisture sensors:

• EC-5 compact, easy to install, low-cost.
• 10HS similar to EC-5, but the 10 cm lenght allows a better sampling.
• EC-TM measures soil moisture and soil temperature.
• 5TE is one of the newest product from DECAGON family and is designed to measure soil moisture, electrical conductivity, and temperature.
• MPS-1 new soil water potential sensor.
• UMS, high-precision tensiometers and pore water sampling tools.

Plant physiology monitoring devices:

• AccuPAR LP-80 is a portable ceptometer designed for in-situ measurements of Photosynthetically Active Radiation (PAR) and determination of Leaf Area Index (LAI).
• SC-1 easy to use, compact leaf porometer used to measure stomatal conductance.
• LWS - leaf wetness sensor.
• Root Scanner, Hand-held Photosynthesis System, Laser Area Meter, Digital Plant Canopy Imager, produced by CID INC., USA.
• CCM-200, a compact Clorophyll Concentration Meter designed to make measurements quickly and store them by the thousands.

Dataloggers:

• Em50 and Em50R are 5 channel intput dataloggers specifically designed for analog and digital sensors and for long-term outdoor use. The Em50R has a radio telemetry module that can transfer data to a DataStation or Rm1.
• Em5b - is a five-channel mini-logger for use with analog sensors only. It is a low-cost, limited-use alternative to the Em50 datalogger.
• Wireless Dataloggers.

Soil respiration monitoring system:
The gradient method based soil respiration system was developed and tested at Utah State University by Dani Or, Scott Jones, and Vasile Turcu*.
