BWK 2000

Soil-water inspection

The BWK measures with a shielded, volumetric capacity-high-frequency technique whereby the water and soil volume density are both used to determine the soil moisture content. Because soil density can vary within a soil layer, a single measurement can only be used to indicate the moisture tendency. Multiple measurements at the same soil layer are necessary in order to calculate a meaningfully accurate value.
The temperature, pH value and salt content do not influence these measurements. The BWK lance delivers quick and simple results. It features a strong, sturdy lance made of stainless steel. The display shows customized colour scales for sand, loam and clay.


There is an LCD for the display. The device is easy to calibrate.

Bambach-BLUMAT plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
