EC-5, Soil Moisture: Our work horse soil moisture sensor. Measures Volumetric Water Content only. Just 5 cm long with a 0.3 L measurement volume, this handy little sensor is easy to install in the field and can also be used in nursery pots. The EC-5 delivers research-grade accuracy at a price that makes large sensor networks economically practical. With the EC-5, you can adequately characterize your site with sensors at multiple depths and locations.
10HS, Soil Moisture: At 10 cm long, this sensor measure volumetric water content in a larger soil sample. The 10HS has a 1 liter volume of influence. High frequency oscillation and patented signal filtering deliver excellent accuracy and minimal textural effects. If you are focused on water content only and are interested in a large volume of influence, this sensor is more than capable.
5TE, Soil Moisture, Temperature and Electrical Conductivity: Our full-featured soil moisture sensor, the 5TE measures volumetric water content, temperature, and electrical conductivity in soil. This three-pronged, 5 cm long sensor is for use in soil only. High frequency oscillation and patented signal filtering deliver excellent accuracy with minimal textural effects. If you need to measure volumetric water content, electrical conductivity, and/or temperature, and if you are managing salts in your system, this is the sensor you are looking for.
5TM, Soil Moisture and Temperature: Get temperature data integrated with your soil moisture data—at the same location and over the same measurement intervals. The 5TM is ideal for adding temperature to each measurement site. The 5TM is ideal if you are interested in mechanisms that are affected by temperature or if you anticipate temperature change in your soil.
MPS-1, Water Potential Sensor: The MPS-1 measures a wide range of soil water potentials (-10 to -500 kPa (pF 2 to pF 3.71)) without user maintenance and factory calibration. The MPS-1 has been used for deficit irrigation monitoring and control, water potential monitoring in the vadose zone, crop stress, waste water drainage studies, and plant water availability.
Leaf Wetness Sensor: This sensor, that closely mimics the wetness state of real leaves, detects wetness and ice formation. Uses for the Leaf Wetness Sensor include predicting when to spray crops, quantifying water storage in the plant canopy, and studying and monitoring crops for foiliar diseases including rust and blight.
Rain Gauge ECRN-50: The best rain gauge for measuring irrigation events. This durable,self-emptying gauge is made of UV, water and frost resistant plastic. The ECRN-50 can also be reconfigured to measure the output of irrigation systems in terms of gallons or liters per hour.
Rain Gauge ECRN-100: The best rain gauge for measuring precipitating and for use in micro-climate monitoring. This durable gauge is made of UV, water and frost-resistant plastic.
ECT, Soil Temperature: The simple ECT soil temperature sensor is an easy-to-use sensor for measuring the temperature of soil, air (with the radiation shield), or other materials. The sensor is completely water proof, submersible, and designed for continuous outdoor use.
EHT, Relative Humidity/Temperature: This compact 3 cm x 1cm sensor Measures air temperature and relative humidity. The included radiation shield improves air temperature and relative humidity readings at the sensor’s location. Outputs both values as a digital signal.
PS-1, Pressure Switch: Ads irrigation water on/off data into the soil moisture data set. This allows the user to track irrigation events with the rest of the soil moisture data by recording when water is turned on and off.
QSO-S PAR, Solar Radiation Sensor: PAR is often used to generate interception, which is then used to predict biomass production, crop growth, etc. This simple, no-frills sensor measures photosynthetically active radiation over your chosen interval.
PYR Total, Solar Radiation Sensor: Total solar radiation data is used to calculate an energy balance, to distinguish between latent heat flux and sensible heat, and as in input in the Penman-Monteith equation, among other things. This simple, accurate sensor allows you to measure total solar radiation over your chosen interval.
Davis anemometer; Wind Speed and Direction: measures wind speed and direction over your chosen measurement interval without complex setup, maintenance, or programming.
