Mackintosh Probe
The Mackintosh Probe is a hand-operated, lightweight and portable penetrometer.
It is a considerably faster and cheaper tool than boring equipment, especially when the soils under investigation are soft or loose.
It can be used to a depth of 16 metres.
The kit consists of:
- 1 x Mackintosh probe hammer
- 6 x 1m rods (9/16 BSF)
- 5 x knuckles (9/16 BSF)
- 1 x Mackintosh probe point
- 1 x heavy-duty carry bag
Professional Mackintosh Probe for In-Situ Soil Testing
The Mackintosh Probe is a well-established, lightweight tool for sub-surface investigation and in-situ soil consistency testing. At TT Precision, we manufacture high-quality Mackintosh Probe kits for geotechnical engineers, surveyors and site investigators who need a reliable, portable method of assessing ground conditions. Primarily used in soft soils, peat and clays, the probe allows rapid data collection on soil strength and the depth of different strata, making it a valuable tool for preliminary site surveys and foundation design.
Precision Engineered for Accuracy and Durability
Our Mackintosh Probe is engineered to deliver consistent, repeatable results in demanding field conditions. The test is carried out by dropping a 4.5kg hammer from a fixed height of 300mm onto a string of connected 1m drive rods. By recording the number of blows needed to drive the cone into the ground, technicians can assess the soil’s resistance and consistency. Every component, from the steel rods to the couplings, is manufactured to close tolerances to minimise energy loss during driving and give you dependable sub-surface data.
The Versatile Choice for Site Investigations
One of the main benefits of the TT Precision Mackintosh Probe is its portability. Unlike a drilling rig, the whole kit can be hand-carried to remote or restricted-access locations, such as steep embankments or enclosed gardens. When paired with our Rod Lifting Tool, extracting the rods is just as quick as driving them. Whether you are carrying out a small domestic survey or a large infrastructure assessment, our Mackintosh Probe kit is a cost-effective way to understand the ground beneath your feet.
