Description

The TDR-315 is a true Time Domain Reflectometer system (minus the coaxial cable) wrapped up in a small, rugged, permanently installable package. This model uses half the power yet it sacrifices none of the accuracy of its big brother the TDR-315. Acclima True TDR technology is a major, patented breakthrough in soil water and EC measurement technology.

TDR-315L
Volumetric Water Content (0 to 100% with 0.1% resolution)
Permittivity (1 to 80 with 0.1 unit resolution)
Soil Electrical Conductivity a.k.a. Bulk EC (0 to 5000 ?S/cm -resolution depends on reading range)
Soil Temperature (-40 to +60°C with 0.1 degree resolution)
Pore Water Electrical Conductivity (0 to 55000 ?S/cm)

Features:

10 meter, flexible, waterproof cable
15 cm X 3.5mm stainless steel 3-element waveguide
Rugged, waterproof epoxy housing
Typical 350ps incident wave rise time applied directly to the soil (no bandwidth limiting coax cable).
Input bandwidth to the waveform digitiser is also unrestrained because of the absence of a coax cable.

This product is compatible with Datastream.
