Delivering Precise Soil Conditions for Efficient Crop and Turf Management

"True time domain sensors have been very expensive in the past, which is why they have not been much used other than in agricultural and environmental science. The relatively inexpensive ($100’s) sensors that were purported to be TDR sensors in the past, were not true time domain sensors. New, relatively inexpensive true time domain sensors are now available in the market (Acclima TDR-315 and ACC-TDT)." --USDA Presentation: Soil Water Sensors for Agriculture


True TDR-315 (SDI)

Completely intergrated TDR accurately yields VWC and BEC/PWEC with a high-speed 150 pico-second rise time for a detailed wave form analysis.

True TDR-315L (SDI)

Also a fully integrated TDR, the 315L consumes less power than its sibling, but still maintains a 300 pico-second rise time for superb accuracy.

True TDR-310S

True TDR-310S(SDI) with rounded form factor

This TDR is from the same family of the other Acclima True TDRs, however its rounded form factor allows it to easily attached to a (sched. 40) 1" PCV pipe and/or be inserted into an access tube as small as 1.25" (sched. 40 PVC) to be inserted into the soil at a specified depth.
