The WatchDog 3250 Wireless ET Station measures temperature, relative humidity, rainfall, solar radiation, and wind speed & direction. Use real-time ET data to effectively irrigate for optimum yield.

The WatchDog® 3230 Wireless Plant Growth Station measures, records, and communicates the important crop growing conditions in a greenhouse. The portable station has an integrated solar power system.

Measures PAR light intensity, Daily Light Integral (DLI), day/night average temperatures, degree days, vapor pressure deficit (VPD) and more!

Data log current conditions and historical plant disease severity indicators. Includes 1000 Series Micro Station, sensors, and radiation shield.

Stay ahead of devastating foliar diseases and insects. Our multichannel disease weather station can increase profits through timely decision making. The WatchDog Plant Disease Station combines convenience with a reliable package of monitoring and data logging capabilities designed to alert you to conditions that lead to disease.

Monitor conditions crucial to growing high quality plants. Includes 1000 Series Micro Station, sensor, and radiation shield.

Study soil and air temperature trends across multiple microclimates.

Measure the light “falling” on your plants. New for 2015 - Greenhouse and Turf versions with updated DLI ranges and labeling. Increase plant growth and quality. Simultaneously compare light between multiple locations. Simple, one button operation. Affordable, first step in measuring light. Meter runs for 24 hours and calculates the Daily Light Integral (DLI). Real-time intensity levels are shown in µmol·m-2·s-1 every 4 seconds over the course of a day. Measures PAR light (Photosynthetically Active Radiation - 400-700nm). Battery included; water resistant.

Plants use the Red/Far-Red light ratio to determine how crowded they are, and grow tall or full accordingly.

Track soil moisture, salts, and soil temperature: all with a single sensor! Whether it’s container pots in a greenhouse or turf on a putting green, the salinity of the root zone is a critical element for healthy plant growth.  Irrigation, fertilizers, and crop demand all impact salt concentrations.  High levels can damage the plant: low levels can lead to nutrient deficiencies.
