The LTLN Caliper is our standard model we carry in stock for laboratory, machine shop, and quality assurance applications.  These calipers are superior to the plastic housed digital calipers commonly available.  Made with hardened stainless steel, all metal housing, these calipers are easy to use and durable.  Feedback from customers are that these calipers are a pleasure to have in the shop.  We use this model at Lightspeed Technologies routinely for quality assurance and design work.
