Precise as a laboratory and as mobile as a cell phone.

This TDR device measuring the soil moisture content, the soil conductivity EC, and the level of salt contamination can now be performed as fast and easy as never before! Within two seconds, the moisture content value, the temperature, and the soil conductivity EC are displayed on its clear display.

  • The probes will report soil EC as standard simultaneously with soil moisture content percentage.
  • The probes measures conductivity with the same large soil volume as it will be used for the TDR moisture measurement.
  • It’s durable and waterproof construction ensures safe handling even under difficult environmental conditions.

Soil Moisture readings for top layers

Using a highly accurate TDR probe for:

  • Highly accurate TDR technology
  • Direct measurement of soil moisture content
  • Integrated soil temperature sensor
  • Soil electrical conductivity measurements
  • Large measurement volumes
  • User replaceable rods.

Benefits at a glance

  • Extremely robust and stable
  • Powerful battery for hundreds of measurements
  • Easy use with one hand via four buttons
  • High reliability even under challenging environmental conditions

Applications and advantages

  • Connected to the TDR is the two-rod probe
  • Based on radar technology
  • Handy two-rod probe with solid rods
  • Measurement via radar technology with an electromagnetic TDR impulse with 1 GHz to measure the water content precisely to material saturation
  • Display of measuring value within two seconds
  • Robust and watertight structure
  • Probe can be connected to a PC for data collection, change of operation mode or calibration
  • Delivery with a resistant hard shell case for trouble-free transport

Choo Choo Desk
Color: White, Size: 40inch without Power Outlet
When looking for a desk; you're considering size and practicality for your purchase. Additionally, you're hoping the assembly of the desk will not require a brain surgeon to apply assembly. As this is my second Choo Choo Desk purchase; both the price, size, practicality and assembly are top notch. My wife uses one as her craft/sewing platform and the other as her computer desk. In placing both side by side, she can negotiate from one to the other with little to no effort and as it offers enough room on each platform with drawers for her notions, notebooks and patterns; She is quite content with her Choo Choo Desk(s) set up. For those searching for a great desk, this Choo Choo set is ideal for minimum sized areas. One has a power bar with A/C and USB ports while the other is a simple desk corner to corner.

Good quality desk for the money
Color: White, Size: 40inch without Power Outlet
Overall this is nice little desk, cute, sturdy, and relatively easy to put together by myself. I took one star off because the bottoms of the desk drawers was missing. I contacted the seller and initially got a pretty quick response that the manufacturer would send replacement pieces and provide the shipping tracking information from the warehouse as soon as they had it. Then a few weeks went by without any word and I couldn't seem to contact anyone again (every link came up broken) so I thought I was essentially ghosted. But then they did contact me with the tracking information and eventually sent the replacement drawer flats. So it took almost two months to resolve but I did get the missing pieces and overall I'm pretty happy with this desk as it was exactly what I wanted for my small home office.
