A Limited Access Machine for Interior and Basement Work

This powerful little machine was designed specifically to be durable yet as lightweight as possible. At 23 in. wide, 62 in. tall (folded), and weighing less than 425 lb., the 420M can be manually lifted and carried to remote sampling locations. It can also be deployed to hard-to-reach and narrow sampling locations. The 420M is powered by a remote hydraulic power source (sold separately) which easily attaches to the machine or by using the auxiliary hydraulics from other Geoprobe® machines.

Macro-Core® MC5 Soil Sampling System

Macro-Core® MC5 Soil Sampling System

Typical tooling that can be run with the 420M include:

  • 48-in. Direct Push Tooling
  • Probe Rod Sizes: 2.25 in., 1.5 in., 1.25 in.
  • Macro Core® MC5 Soil Sampling
  • LB Soil Sampling
  • DT22 Soil Sampling
  • SP22 Groundwater Sampling
  • SP16 Groundwater Sampling
  • 0.75-in. Prepacked Monitoring Well Installations

Video: Macro-Core® Center Rod

Our MC5 Soil Sampling System is a single tube, discrete or continuous system with unmatched durability.

MC5 Light Weight Center Rod Soil Sampling System The MC5 1.25 in. Center Rod System was designed for the absolute worst of the worst direct push probing conditions. “These are conditions that we normally do not recommend probing in,” according to Mike Carlin, Project Engineer, “so we developed the toughest soil sampling system in the direct push industry ... it’s a brute!”

Video: DT22 Soil Sampling System Overview

The Geoprobe® DT22 Soil Sampling System is a direct push system for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25 in. outside diameter probe rods. Samples are collected and retrieved within a liner that is threaded onto the leading end of a string of Geoprobe® 1.25 in. OD light-weight center rods and are inserted to the bottom of the outer casing.

The Geoprobe® Screen Point 22 System

The Geoprobe® Screen Point 22 System

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen.

The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-in. Lightweight Center Rods or PVC riser.

The screen head adapts to either a stainless steel or PVC screen. Designed for tough probing conditions, the fully retrievable sampler works well with the 8040DT machine or with 77 or 66 Series machines.
