The Geoprobe® Model 54LT direct push machine is a rugged, compact probing unit designed for tight spaces and rough terrain. This unit is narrow enough to fit through standard 36-in. doors to get to confined, enclosed places a vehicle-mounted unit can't get to.
ASTM and International Standards require that CPT tools be pushed at a rate of 2 cm/second with very little variance allowed. The Model 54LT machine features a Probe Cylinder Speed Control Valve which makes it easy to push at this consistent speed even without a steady hand. Not only will this increase the accuracy of your test while probing, it allows you to pay more attention to your real-time CPT log as you go.
