Stainless / IP54
For workshops, outdoors, or anywhere with water and chips, choose stainless or IP54. The IP54 model adds sealing against liquid and debris, which is friendlier to machining.

Frequently Asked Questions
What is the difference between a digital 6-inch caliper and the rechargeable version?
The basic digital model runs on coin cells. The rechargeable version uses Type-C charging, needs no battery swaps, and some models add a backlight and power display.
Do I need an IP54 caliper?
If you measure near machines, outdoors, or anywhere with water and chips, choose IP54 for better protection and longer life.
Stainless vs. standard digital caliper?
A stainless body resists rust, ideal for humid shops or cutting-fluid environments. Standard digital bodies are usually engineering plastic or aluminum.
Final Verdict
Pick by environment, not by brand. Dry bench and 3D printing → basic digital. Humid or cutting-fluid shop → stainless. Machine shop with chips and coolant → IP54. Hate battery swaps → Type-C rechargeable. All seven 6-inch SKUs above are in stock.
