Our Products
Our offered Product range includes Acclima Digital True TDR-310H Soil Moisture Sensor, Acclima Digital True TDR-315H Soil Moisture Sensor, Acclima True TDR315N Soil Moisture Sensor, TEROS 11 Advanced Soil Moisture and Acclima Digital True TDR-310N Soil Moisture Sensor.
The TDR-310H is one of Acclima’s H-series sensors, which are very low power and suited perfectly for power-conscious applications. Being part of the Soil Smart Series means that it’s advanced waveform analysis works with all mineral soil types. It is a complete integrated time domain reflectometer that combines ultra-fast waveform generating and digitizing functions with a precision 5 pico-second resolution time base and highly sophisticated waveform digitizing and analyzing firmware that provides true time domain analysis of soil-propagated waveforms.
Its form factor is designed for easy vertical installation in an augered hole using a 34 mm flat-bottomed auger. It mates with a 1” schedule 40 PVC pipe that acts as a handle in its installation to any desired depth. It provides reading data through a 3-wire SDI-12 interface and is compatible with any data recorder that is compliant with SDI-12 version 1.4 and earlier.
Key Features
Measurement Functions
A fully integrated digital TDR soil water content sensor, the 315H consumes a fraction of the energy than that of its soil moisture sensor siblings in the N series, but still maintains a 150 pico-second rise time for superb accuracy. Not intended for soils with high clay content or bulk EC above 1800 µS/cm.

The TDR315H is a true Time Domain Reflectometer soil moisture sensor designed to provide highly accurate Volumetric Water Content Measurements in soils and other porous media. It incorporates the same basic TDR components found in console-based TDR instruments costing 20 times more – housed inside the small enclosure that also supports the 15 cm waveguide.
The patented TDR function is coupled directly to the waveguide, thus eliminating the coax cable associated with conventional TDR devices. The absence of the coax cable provides the TDR315H with higher bandwidth waveform data thus improving its resolution and sensitivity over expensive conventional TDRs.
The TDR-315H is the replacement to the former Acclima TDR-315 and TDR-315L soil moisture sensors. It is fully compatible with those sensors but incorporates several improvements. It is a complete integrated time domain reflectometer that combines ultra-fast waveform generating and digitizing functions with a precision 5 pico-second resolution time base and highly sophisticated waveform digitizing and analyzing firmware that provides true time domain analysis of soil-propagated waveforms. Its form factor is designed for shallower horizontal installations where it is forced into the sidewall of a trench that has been dug to the desired measurement depth.
Its main improvements over the 315L soil moisture probe are its faster rise time, its shaped incident wave, its lower power consumption and its very fast response time. Its rise time is as fast as the TDR-315 but its power consumption is much lower than the TDR-315 and its price is also lower.

The TDR-315N is a replacement to the former Acclima TDR-315L. It has a high voltage waveform output, which makes it effective in taking measurements when the soil electrical conductivity is high. It also consumes more power than the TDR-315H. It is a complete integrated time domain reflectometer that combines ultra-fast waveform generating and digitizing functions with a precision 5 pico-second resolution time base and highly sophisticated waveform digitizing and analyzing firmware that provides true time domain analysis of soil-propagated waveforms. Its form factor is designed for shallower horizontal installations where it is forced into the sidewall of a trench that has been dug to the desired measurement depth.
A probe guide is provided to ensure that the waveguide rods are parallel when pushing them into the soil. It provides reading data through a 3-wire SDI-12 interface and is compatible with any data recorder that is compliant with SDI-12 version 1.4 and earlier.

Measurement Functions
The TEROS 11 uses a completely new calibration procedure that maximizes accuracy and minimizes sensor-to-sensor variability while keeping the cost reasonable. So you can be confident that every sensor you install is going to read exactly like the next one. Unlike other sensors on the market which spec an unverifiable ±1.0% VWC accuracy, the TEROS 11 was rigorously tested by our soil physicists across a challenging range of soil types and EC levels so you can be confident in the accuracy of your data.
Plus, TEROS sensor repeatability can be checked with an accuracy verification standard. No other soil moisture sensor has this ability. Just slide the verification clip onto a sensor and plug it into a logger. If it reads within the right range, your sensor is good to go.
