1.Center guide rod using imported materials, high precision, wear-resistant. 2.Use of super-hard aluminum shell.

1) Center guide rod using imported materials, high precision, wear-resistant;

 

2) Use of super-hard aluminum shell to avoid on-site work injury apparatus, to extend the service life;

 

3) Pointer slider with external spring ring structure, both convenient for the friction adjustment, and ensures that the pointer shaft and pointer slider friction uniform, to ensure the accuracy of the instrument.

Technical   Data

Measuring ranges: 10-60MPa Impact energy: 2.207J(0.225Kgf.m) Spring extension: 75mm The static friction of pointer slider: 0.5N±0.8N Radius of spherical tip : 25mm±1mm The average rebound values on steel anvil: 80±2 Housing dimensions: Φ54*278mm Weight: ≈0.75Kg Measurement: 345*85*80 mm

High accuracy, quality and cheap, long service life.
