SOIL SOLUTION ACCESS TUBE - MODEL SSAT 1AR46METE;r IRROMETER Soil Solution Access Tube— SSAT SSAT (Soil Solution Access Tubes), or Suction Lysimeters, were developed to easily extract soil water samples for testing. They provide the user with an accurate method of determining salinity or plant nutrient levels. Because the sample is collected at root zone depth, it reflects the true w impact fertilization has on the plant material, Understanding soil water conditions helps the user make informed fertigation scheduling decisions } 't, resulting in improved yield and reduced fertilizer, water,labor and energy costs. # Features: • Easy to install and use • Standard ceramic tip(white)for most soil types ' • Low Tension tip(blue)for sandy soils 1. and growing media • Optional Double Suction line for longer tubes Specifications- • Collects soil water sample at the root zone WATER TUBE MATERIALS: 1� Butyrate body,ceramic tip, t ( OPERATING PRINCIPLE:The SSAT shares a few Construction features neoprene stopper,vinyl `.�; with the very popular IRROMETER instrument which measures tubing suction line,plastic r: soil water tension,The SSAT consists of a sealed plastic tube that suction line clamp s } is equipped with a porous ceramic tip on the bottom end.The tube DIMENSIONS: `. is installed in the ground With the ceramic tip placed at desired HEIGHT:Ranges from 6 in.to 72 in, ; root zone depths. After an irrigation/fertigation event, a slight (15 cm to 180 cm) Y (special lengths available) 1 t vacuum is applied to the tube which has a suction line extending DIAMETER: .875 in.(22 mm) past the top seal and a clamp to seal it off,The vacuum in the tube draws soil water through the porous ceramic tip where it INSTRUMENT in.( WEIGHT. i accumulates in the tube.To collect the sample from the tube the 12 in. g)With is increases Ib. .q operator simply connects a syringe to the suction line,un-clamps of.5 kg)with increases ate, the tubing and draws it out or,using the double suction line option, of.252 Ib.(.114 kg) ' pressurizes the tube to push the sample out.The sample can then perfoot t be analyzed in the field or at the laboratory.
