THE TDR-305N

Completely integrated TDR soil moisture sensor accurately yields VWC and BEC/PWEC with a high-speed 300 pico-second rise time for a detailed wave form analysis. Designed for high EC tolerance when taking readings.

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-305H has been specifically designed for tighter spaces. Also suited to auger installations if desired.

Compatible with our RD1200 Handheld Reader.

DATA CAPTURED:

1. Volumetric Water Content (0 to 105% with 0.1% resolution)

2. Temperature (- 40 to +70 degrees C with 0.1 degree resolution)

3. Permittivity (0 to 100 with 0.1 unit resolution)

4. Bulk EC (0 to 10000 μS/cm - resolution depends on reading range)

5. Pore Water EC expressed in μS/cm.

Suggested installation method

When side trenching or disturbing the soil from above is not an option, Acclima’s round form sensors are designed to be inserted into a 25mm augered hole to a precise depth of your choosing.

The sensor's recessed shoulders sit on a Schedule 40 25mm PVC pipe pressed into the undisturbed soil at the base of the augured hole giving unprecedented TDR accuracy at any depth in undisturbed soil.
