KSAT Saturated Hydraulic Conductivity

The KSAT is the only automated setup for taking saturated hydraulic conductivity measurements in the lab. In its simplest form, it’s an instrument that uses both the falling and constant head methods on a soil core. Best of all, it’s completely integrated, so you’re also assured of software-controlled engineering that’s fully tested.

  • Accurate
  • Removes human error
  • Directly calculates Ksat
  • Temperature correction
  • Completely integrated package
  • Small footprint
  • Automated
  • Uses both Constant and Falling Head methods
  • Easy-to-use software
  • Wide range
  • Complies with DIN 19683-9 and DIN 18130-1

A recurring core issue

Saturated hydraulic conductivity isn’t an easy measurement to make, mostly because of the lack of a simple-to-use tool. Many soil scientists and engineers resort to cobbling together their own contraptions that are either complicated and finicky, or simple and crude. Neither have proved to be effective setups in terms of accuracy or convenience.

Integration: the key to convenience

Unlike typical contraptions, the KSAT comes with everything you need to make a measurement, meaning you can set it up right out of the box. This type of integration also allows the KSAT to take up minimal bench space.

Automatic ease

As the only automated instrument on the market, the KSAT makes measurements a lot more convenient. The easy-to-use software performs all calculations, including temperature corrections based on the viscosity of water. You can also look forward to eliminating the need to time outflow, weigh beakers and make judgement calls, which collectively add up to significant time savings.

A higher degree of accuracy

The KSAT boasts a wide range of measurement conductivities from 10,000 – 0.1 cm/d. Plus it reads and stores data automatically on your computer via USB, so human error is reduced. And because temperature is corrected before a measurement is made, data quality is also dramatically improved for results you can truly rely on.

Superior saturated hydraulic conductivity measurements

Full integration. Simple automation. Improved accuracy. The KSAT finally checks off all the boxes you care about when it comes to measuring saturated hydraulic conductivity in a compact instrument that saves you time, hassle, and worry.
