Digital Point Load Tester
Product Code : LSK-CL-10597
Digital Point Load Tester (SKU LSK-CL-10597) measures the strength of rock specimens, at site or in the laboratory, by breaking a core between two conical points. Engineering geology, mining and civil engineering departments and TVET materials labs use it to index rock strength quickly. Orders for the tester are handled by Science Lab Supplies in Ambala, India, which prepares quotations for colleges, training institutes, tender contractors and distributors.
Specifications
Each rated figure of the 56 kN point load frame appears row by row below. In brief, a manual hydraulic jack presses two cone-shaped points against the core, a graduated scale gives the point spacing, and a high-precision electric load cell shows the load on a digital display, all packed in a wooden carrying case.

Applications and Experiments for the Point Load Tester
The tester gives the point load strength index of rock, a quick measure used to classify rock strength without cutting and grinding specimens. It is used in engineering geology and rock mechanics practicals and in site investigation training, where drill cores are tested in the field.
- B.E./B.Tech civil and mining engineering: rock mechanics practical on the point load strength index, set beside soil shear strength work on the Direct Shear Apparatus.
- Diploma and TVET civil, geology and mining technician courses: testing drill cores during site investigation exercises.
- Materials testing labs: screening rock intended for aggregate or building stone, together with specific gravity and absorption checks using the Dunagan Test Set.
The index is calculated as Is = P/D², where P is the failure load and D the distance between the conical points. Wear the supplied goggles, since rock fragments can fly when the specimen breaks.
Standard Scope of Supply
The tester is supplied complete with its wooden carrying case, safety goggles and accessories, together with the load frame, manual hydraulic jack, conical points, graduated scale and the load cell with digital display unit. The case keeps the set together when it is carried to site.
Packing, MOQ and Lead Time
You can ask for a quotation for one tester or for several units for a department or training centre, and the quotation sets out packing, delivery time and price for that quantity. Other vocational training equipment for your materials lab can be listed on the same quotation.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter and can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. A rock mechanics lab can request figures for this tester by writing via the contact page or listing it in the enquiry cart; departments bound by procurement rules will find bid guidance on the lab tender page.
Frequently Asked Questions
What does the Digital Point Load Tester measure?
It measures the load needed to break a rock specimen between two conical points. With the point spacing read from the scale, this gives the point load strength index used to classify rock strength.
What size of specimen can it take?
Core specimens up to 4 inches (101.6 mm) in diameter. The frame applies up to 56 kN through a manual hydraulic jack, and the display resolves 0.001 kN.
Who supplies the Digital Point Load Tester?
Science Lab Supplies, working from Ambala in India, is the supplier. Its quotations reach colleges, training institutes, contractors and distributors directly, and other rock or aggregate testing items can be priced on the same document.
