The borehole infiltrometer head houses the water level depth sensor (to control the water level), water connection, and air connection with push-to-connect fitting. It extends the functionality of SATURO units. If you are buying a new SATURO and want to take measurements below the soil surface, you can order a complete Borehole SATURO package. This kit allows you to add borehole measurement capabilities to your instrument kit without purchasing a new control unit.

The SATURO borehole accessory kit includes everything you need to extend your SATURO measurements below the soil surface:

• Borehole infiltrometer head
• 10-cm (4 in) hex quick pin
• A pair of 1 m (3 ft) extension rods with hex quick pin
• Slide hammer with hex quick pin
• Auger handle with hex quick pin
• 10-cm (4-in) finishing auger with hex quick pin
• Two 3/8 in x 1 3/4 in pins
