The TDR-305N is a modified version of the TDR-310N. The very short waveguide allows this sensor to make very shallow measurements and to be used in higher conductivity environments with a sacrifice in total measurement volume.
The TDR-310H is the replacement to the former Acclima TDR-310S. It is fully compatible with the ‘310S but incorporates several improvements.
The TDR-310N is a replacement to the former Acclima TDR-310L. It has a high voltage waveform output, which makes it effective in taking measurements when the soil electrical conductivity is high.
The TDR-310W is a modification to the Acclima TDR-315N. Its shorter rods allow it fit in standard rockwool blocks.
The TDR-315H is the replacement to the former Acclima TDR-315 and TDR-315L. It is fully compatible with those sensors but incorporates several improvements.
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.
The Acclima Digital TDT® soil moisture sensor represents a revolutionary advance in the irrigation industry. It is the first soil moisture sensor to incorporate the accuracy of digitized Time Domain Transmissometry in a low-cost instrument providing highly accurate absolute readings of soil moisture.
This manual is for all current model Acclima TDR Sensors. For specific information such as physical properties and measurement capabilities, please consult the data sheet for the specific sensor.
Why Acclima soil moisture sensor technology is superior in terms of accuracy and cost.
