Product Overview

Core Product Competitive Advantages

1. Non‑destructive sample‑friendly measurement
   No need to cut large test coupons. Real‑world measurement can be executed directly on original hide surfaces. It avoids wasting valuable leather raw‑materials and supports multi‑point mapping inspection across full‑size hides.
2. Dual read‑out options: digital or analogue dial gauge
   Digital‑display variant delivers 0.01 mm resolution for high‑accuracy‑demanding projects; dial‑pointer version offers cost‑effective reliable readings for routine batch QC. Both versions follow identical standard mechanical‑loading principles.
3. Interchangeable aperture rings for diverse‑material testing
   Supports swapping 20 mm and 25 mm restraining rings. 25 mm ring applies for general leather testing; 20 mm ring adapts for fabric and relatively soft thin‑material samples, expanding instrument application coverage.
4. Stable standard dead‑weight loading system
   Total test load maintains 530 ± 10 g as required by international norms. Internal guiding mechanism ensures probe descends vertically without lateral offset, minimising manual‑operation‑caused measuring deviationANSI Webst….
5. Robust portable compact construction
   Key contact components adopt anti‑corrosion stainless‑steel. Overall unit is light‑weight for easy transport between workshop floor and laboratory bench. Simple manual‑press operation lowers operator‑skill threshold.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation
   Place the tester on flat stable work‑surface. Select corresponding restraining ring based on test‑material (leather or fabric). Perform zero‑point calibration before batch measurement. Prepare original leather specimens without cutting small coupons.
2. Specimen Positioning
   Lay leather flat on base aperture area. Make‑sure test zone sits right above the selected ring opening, keep material free of wrinkles, folds and local tension.
3. Execute Softness Measurement
   Press down the operating handle steadily. The loaded probe descends vertically and indents the leather surface. Once movement stabilises, directly record softness‑depth reading from digital screen or dial scale.
4. Multi‑Point Sampling & Data Recording
   Take repeated readings at different locations of one hide. Document each measuring value to assess intra‑piece softness uniformity. Complete parallel sampling for different batches for cross‑batch comparison. Multiple measuring points are suggested for statistically‑valid results.
5. Post‑Test Tidying
   Lift handle to reset probe position. Wipe probe and ring surfaces to clear leather dust. Keep instrument stored in dry environment. Re‑verify zero‑point status before next‑group testing.
