Ceramic Cup Lysimeter Systems Help You Collect Water Samples
Excellent for vadose zone monitoring, Ceramic Cup Lysimeter Systems are soil pore water collection devices designed for permanent installation beneath the ground surface. Use the two-line systems with Vacuum Pressure Pump No. 220693, sold separately. The vacuum is pulled and the vadose water flows into the ceramic cup. The pressure line is then used to push the sample to the surface. The ceramic cup features pore size of 0.446μm.
The Shallow-Sampling Lysimeter (No. 220690) is designed for installation down to 20 ft., while the Deep Sampling Lysimeter (No. 220691) is designed for installations down to 300 ft. Both Lysimeters use the same pressure/vacuum principle, however the Deep-Sampling Lysimeter has a ball check valve that protects the porous chamber from the higher pressures required to retrieve the samples from greater depths. For very deep installations, a compressor may be necessary to provide sufficient pressure. A second ball check valve is installed in the sample line.
Lysimeters are designed for use with the Pressure Vacuum Hand Pump, No. 220695.
Place the Lysimeter at the desired depth while protecting tubing with 1-1/2" dia. x 5'L PVC Lysimeter Extension Casing, No. 220696.
Neatly secure the tubes from your Lysimeter at the ground surface with the Lysimeter Well Head Assembly, No. 220693.
