Looking for a logger to power your sensors and read and store the measurement data? The Em50 series simplifies data logging with: Pre-programming. No user programming necessary. An internal power supply (5 AA batteries). No external power source…
Integrate Climate Variables Account for environmental variables with simple, accurate, plug-and-log sensors. Get Local Weather Measure weather data where you are, not 5 miles away at the Met tower, so that you can measure environmental variation on…
Standard field tensiometer. Only the ceramic cup is filled with water to improve accuracy and offer year-round operation. Optionally with external refilling: The model T4e with external refilling can be refilled or emptied without removing it from the soil.
</p> Which sensor is right for my application? Soil moisture is highly variable. Accuracy from a single site isn't enough to run an experiment. To make good soil moisture measurements, you need research quality probes and you…
Accurate, Affordable, Practical Stomatal Conductance The SC-1's breakthrough steady-state technology makes getting accurate stomatal conductance measurements affordable and practical for everyday research. No Moving Parts The SC-1's steady state…
Large-scale lysimeter measurements in a smaller package and a lower price. A complete small weighable and tension controlled field lysimeter. Combined with tensiometers, soil moisture sensors, data logger with optional GPRS modem, lightning protection, and powered by solar panels. This is the idea of the UMS Smart Field Lysimeter.
Close Your Water Balance Get closer to completing the water balance equation with this system that helps you nail two tough components: storage and deep percolation. Measure Deep Drainage The Drain Gauge is elegantly designed to make sure water…
The ECRN-100 is best used in research studies or for measuring precipitation. Plug-and-log capabilities with the Em50 series data loggers. Resolution: 0.2 mm (0.01 in); collector surface 200 q/cm.
Rain gauges for measuring incoming moisture: one for research and natural precipitation, one for irrigation.
The 10HS measures volumetric water content in a larger soil sample with its 1 liter volume of influence. High frequency oscillation and patented signal filtering deliver excellent accuracy and minimal textural effects; analog output makes it easy to use with other companies' data loggers including those manufactured by Campbell Scientific. This 10 cm long probe works best when installed in the field.
Total solar radiation data have a wide range of uses, including distinguishing between latent heat flux and sensible heat, calculating an energy balance, and calculating evapotranspiration using the Penman-Monteith equation. This simple, accurate sensor allows you to measure total solar radiation over your chosen time interval. Plug-and-log simplicity when used with the Em50 line of data loggers.
The VP-3 Vapor Pressure/Humidity/Temp Sensor with Radiation Shield measures air temperature and relative humidity and outputs all three values as a digital sensor. Plug-and-log capabilities with the Em50 line of data loggers.
Use these environmental sensors to characterize water movement beyond the soil. Useful for environmental modeling, completing a water balance, and just generally describing how water is moving through the soil-plant-atmosphere…
Field tensiometer's water level indicator tells you when to refill. Also measures temperature and has an external refilling option.
These modernized tensiometers, built by German company UMS, are THE most accurate way to measure soil matric potential. Thanks to precision engineering, meticulous construction, and fanatical attention to detail, they have terrific accuracy and a range that (with a skilled operator) can extend beyond -200 kPa.
Low cost, limited use five-channel mini-logger. Powers and reads analog sensors (EC-5 and 10HS soil moisture sensor, rain gauges, ECT temperature sensor). Best for inexpensively adding spatial resolution to soil moisture studies.
