Overview
The ET107 is an automated weather station designed for irrigation scheduling in turf grass and commercial agriculture applications. The station calculates potential evapotranspiration (ETo), which is the amount of water lost from the soil due to evaporation and plant transpiration. Calculating evapotranspiration rate can aid in the development of an irrigation schedule that provides sufficient water without overwatering.
Key Advantages
for better irrigation scheduling
Technical Description
Our ET107 ETo station consists of meteorological sensors, an aluminum 3-m pole, and an environmental enclosure that houses a CR1000M module and a 7-Ahr sealed rechargeable battery. The battery is recharged via ac power or a 10-W solar panel. Sealed circular connectors are provided on the outside of the enclosure to simplify sensor hookup.
Meteorological sensors included with the ET107 are the CS305-ET Solar Radiation Sensor, HMP60-ETS Air Temperature and Relative Humidity Probe, TE525-ET Tipping Bucket Rain Gage, and either the 034B-ETM Wind Set or WindSonic1-ETM 2-D Sonic Wind Sensor.
The ET107 can also measure the:

The ETsz() instruction requires the user to input lattitude, longitude, elevation, and crop type for a station's location in order to generate accurate calculations of ET. The Generic_ET_107_ETsz.CR1 and Generic_ET_107_ETsz_Windsonic.CR1 programs use the ConstTable() intruction to create a constants table that allows the user to easily input these values using Loggernet, PC400, or a keyboard display. These values only need to be set once, during station set up.
