5.Frequently Asked Questions
Q1: How does the electronic proportional valve improve sample quality?
A1: Unlike traditional manual or stepped mechanical loading, the electronic proportional valve allows stepless, digital adjustment of grinding pressure, ensuring exact force application without shocking or deforming sensitive materials.
Q2: Is the iPoli-SC-250A easy to clean and maintain in a corrosive chemical environment?
A2: Yes. It is constructed with a Fiberglass Reinforced Plastic (FRP) protective shell and stainless steel standard parts, providing exceptional resistance to water, rust, and acidic polishing suspensions.
Q3: Can this machine handle both batch samples and individual single samples?
A3: Absolutely. Equipped with a pneumatic central and single-force multi-sample clamp, it allows operators to process a full batch of samples or focus on individual specimens with equal precision.
