Avoid painstaking, complicated setups
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 has proven to be an effective setup in terms of accuracy or convenience.
Saturated hydraulic conductivity—simplified
The KSAT is the only easy-to-use automated setup for taking saturated hydraulic conductivity measurements in the lab. In its simplest form, it’s an instrument that uses both the falling head (automated) and constant head (non-automated) 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.
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. But perhaps its biggest benefit is how, as part of the LABROS system, it complements the HYPROP. Both the HYPROP and the KSAT can use the same soil core because they share compatible sampling rings. This enables you to take saturated and unsaturated hydraulic conductivity measurements and generate a soil moisture characteristic curve to get a complete picture of a sample’s properties, simplifying both processes.
Easy and automatic
As the only simplified 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 judgment calls, which collectively add up to significant time savings.
A higher degree of accuracy
The KSAT boasts a wide range of measurement conductivities from 5,000 to 0.01 cm/d. Plus it reads and stores data automatically on your computer via USB, so human error is reduced. And because the data is temperature-corrected, data quality is also dramatically improved for results you can truly rely on.
