HLN‑200 Portable Leeb Hardness Tester
Read：0
The Foosean HLN‑200 portable Leeb hardness tester is a lightweight field‑oriented metal hardness inspection instrument, following GB/T 17394 and ASTM A956 standards. It adopts impact‑rebound Leeb principle for rapid on‑site hardness test for large, heavy or assembled metal workpieces. Compact and easy‑to‑carry, it supports multi‑hardness‑scale automatic conversion, mass‑data storage, wireless printing and PC data communication, widely used in machinery manufacturing, heat‑treatment workshops, metallurgy, casting and on‑site quality inspection departments.
Main Features
Touch‑screen operation: 3.9‑inch high‑brightness touch LCD display, multi‑language UI (English, Chinese, optional German / French / Italian / Spanish / Russian / Polish / Japanese / Korean).
High‑precision measurement: Accuracy up to ±6HLD. Standard high‑precision D‑type impact sensor; host automatically recognizes alternative sensors: DC, C, DL, D+15, G, no re‑calibration required after probe replacement.
Multi‑scale auto‑conversion: Real‑time conversion between HL, HRC, HRB, HB, HV, HSD and tensile strength MPa. Supports 360‑degree all‑direction measurement with automatic direction compensation.
Large‑capacity data storage: Save up to 800 groups of complete test records; support upper/lower tolerance setting and out‑of‑limit alarm for batch inspection.
Standard wireless mini‑printer: Print test reports on‑site without data cable connection.
PC communication software included: Upload stored records to computer via USB for data archiving, statistics and report export.
Built‑in rechargeable battery: Stable power supply for long‑time field inspection, with battery‑level real‑time display.

Application
Suitable for on‑site hardness testing of heavy castings, steel structures, shafts, molds, bearing parts, pressure vessels and assembled equipment.
Note: Leeb tester gives converted hardness values. Not recommended for thin‑wall or small‑mass workpieces below 5 kg, only for rapid screening instead of final third‑party acceptance. For high‑precision field inspection, please refer to our lab reference test can adopt micro Vickers hardness tester.
