Laboratory Grade Intelligent Microhardness Tester (50X Objective Lens & Multi-Scenario Data Management)

--Designed for high-precision material analysis

I. Core Performance Parameters

Testing system

Scale support: Vickers (HV), Knoop (HK), optional Rockwell (HRC) extension module.

Indenter type: diamond positive quadrangular cone indenter (136 ° top angle, Knoop's indenter optional), hardness range 1HV ~ 3000HV.

Load accuracy: 0.5% reading error, support 10gf~2kgf stepless load adjustment (sub-stage: 10/25/50/100/200/500/1000/2000gf).

Optics and Imaging

Dual optical path objective system: 50X high-resolution objective lens (working distance 6.5mm), with 10X eyepiece, total magnification 500X.

Intelligent imaging module: 5 megapixel CMOS camera, built-in AI indentation recognition algorithm, automatic calibration of diagonal length (accuracy ±0.1μm).

Light source configuration: three-ring LED cold light source (adjustable brightness), support bright field/dark field switching, adapt to metal, ceramic, transparent coating and other materials.

Hardware and operation design

Mechanical structure

Integrated cast iron body: vibration damping coefficient ≥ 90%, with air-float vibration isolation table optional (applicable to nano-scale testing).

Full-automatic turret: automatic switching of indenter, objective lens and light source to avoid human collision error.

Carrier stage control: motorized XY stage (stroke 50×50mm), positioning accuracy 0.5μm, support multi-point programming test.

Interactive interface

10.1-inch industrial touch screen: real-time display of hardness value, indentation 3D morphology, hardness distribution heat map.

Multi-language system: Chinese/English/Japanese/German interface, support voice operation prompts (in line with ISO 17025 laboratory specifications).

Third, data management and intelligent analysis

Storage and Output

Local storage: 99 groups of test data (including indentation images, coordinates, time stamps), supporting group labeling (e.g. “Batch A - after heat treatment”).

Cloud synchronization: Directly connect to LIMS system via Wi-Fi, data automatically generate PDF/Excel reports (compliant with FDA 21 CFR Part 11 e-signature specification).

Analyzing Functions

Statistical Charts: Automatically calculate mean, standard deviation, and CPK process capability index.

Cross-material comparison: Database pre-stored hardness reference values for common materials (e.g., 316L stainless steel, Al₂O₃ ceramics), generate comparison curves with one click.

Abnormal warning: AI automatically identifies indentation aberrations (e.g. cracks, material creep) and prompts retesting or parameter adjustment.

Scenario-based application configuration

Scientific research level program

Nanoindentation module: optional ultra-low load below 1gf (resolution 0.01gf), supporting thin film/biomaterial testing.

High-temperature test module: -50℃~300℃ temperature-controlled environment, used for hot hardness analysis of aviation materials.

Industrial quality control program

Barcode/RFID scanning: Bind sample ID and test data to realize full process traceability.

Production line level dustproof design: IP54 protection level, adapting to workshop dust environment.
