Testometric Load Cells
5 N to 1,000 kN.
Class 0.5 Precision.
The most complete interchangeable load cell range for universal testing machines in India. ±0.1% accuracy across every capacity. 800% overload protection. Auto-recognised by winTest™ software — no manual calibration entry, ever.
Load Cells That Outperform the Competition
Every Testometric load cell is engineered to the same exacting British standard, from the smallest 5 N precision cell to the 1,000 kN structural testing cell.
Precision N-Range Load Cells
The most demanding applications — thin films, fibres, medical devices, adhesives, sutures, and pharmaceutical packaging — require sub-newton sensitivity that most load cells cannot reliably deliver. Testometric's small capacity series extends from 5 N (LC0.5) to 1,000 N (LC100), with resolutions as fine as 0.00001 N and minimum accurate readings as low as 0.004 N.
The LC1 (10 N full scale) is the most popular choice for rubber dumbbell micro-specimens, narrow textiles, medical tubing, and suture testing — achieving a minimum reading of 0.04 N at full Class 0.5 accuracy. Pin diameter is 3 mm (LC0.5, LC1) increasing to 8 mm for higher loads, ensuring clean specimen alignment regardless of grip type.

Industrial N-Range Load Cells
The workhorses of materials testing laboratories. This series covers the most frequently tested materials in quality control and R&D environments — rubber, plastics, textiles, geosynthetics, packaging films, composites, and structural adhesives — where forces exceed 1 kN but don't require large-frame capacity.
The LC1000 (10 kN) is the single most widely installed Testometric load cell globally, covering tensile testing of standard rubber dumbbell specimens, HDPE pipes, woven fabrics, fibre rope, and metal coupons. Spigot diameter is 20 mm across the full series (except LC5000 which uses 30 mm), maintaining consistent fixture compatibility.

Frequently Asked Questions
Everything you need to know about Testometric load cells and selection.
Testometric load cells achieve ±0.1% accuracy across their full rated capacity. The complete system accuracy (load cell + frame + electronics) is better than 0.5% of indicated reading — which satisfies Class 0.5 per ISO 7500-1 and Grade B per ASTM E4. Critically, this accuracy is maintained down to 1/1,000th of the load cell's rated capacity, so a 10 kN load cell still reads accurately at 10 N.
Yes. All Testometric load cells use a standardised connector and mounting interface. They can be swapped between any compatible Testometric frame in under a minute. On connection, winTest™ reads the embedded TEDS calibration data automatically — no manual programming required. One 50 kN machine can use a 5 N load cell for precision delicate specimens and a 50 kN load cell for robust materials tests.
Testometric load cells match competitor accuracy (±0.1%) at significantly lower cost. The key differentiators: 800% overload protection vs 150–200% on Instron/Zwick/Shimadzu means your investment survives accidental overloads. The LC0.5 (5 N) is one of the most sensitive UTM load cells commercially available — Instron's entry-level starts at 10 N. And unlike some competitors who limit interchangeability to product series, all 19 Testometric load cell models work across compatible frames.
The LC0.5 (5 N full scale) can resolve forces of 0.00001 N and provides Class 0.5 accurate readings from 0.004 N. Even the LC1 (10 N full scale) — the most popular small-capacity model — reads accurately from 0.04 N (40 millinewtons). This makes Testometric one of the most sensitive UTM load cell ranges available without stepping up to dedicated micro-force platforms.
For standard ASTM D412 / ISO 37 rubber dumbbell testing, the LC100 (1 kN) is typically used for most rubber and silicone compounds. For reinforced rubber, conveyor belt compounds, or tyre sidewall, specify LC250–LC1000. For thin latex films or micro-dumbbell specimens, use LC1–LC10. A single Testometric UTM with 3–4 interchangeable load cells can cover all rubber compound types in one lab.
Yes. Each Testometric load cell contains embedded TEDS (Transducer Electronic Data Sheet) memory holding its complete calibration certificate. When connected to the frame, winTest™ reads this automatically and self-configures — calibration constants, range limits, and unit display all update instantly. Changing load cells takes less than a minute including software recognition.
