Irrometer Soil Solution Access Tube (SSAT) Vacuum Pump
A hand vacuum pump with gauge and tubing adapter is used for applying vacuum to the tube for sample collection.
We recommend using the Vacuum Pump on tubes longer than 12 in. (30 cm) to apply proper vacuum. The extracted soil water samples are commonly tested with electronic meters or portable test kits. This useful in-field sampling technique is quick and easy to perform, which makes it well suited to the frequent fertigation schedules common with certain growing conditions.
