Starrett digital calipers are designed for measuring the internal and external distances of objects in manufacturing, research & development and scientific facilities. These measuring calipers have high contrast, easy to read LCD readout for displaying the measured values to decimal point accuracy. Starrett calipers have inch / millimeter metric conversion and induction type linear encoder system for high accuracy. They provide IP67 level of protection against dust, dirt, coolants and water usually found in machining shops and automotive facilities. These measurement calipers feature wireless data transmission for transferring the data saved to electronic devices and computers. They can transfer the data to devices in a range of 30 feet without any data loss. Starrett calipers have hardened stainless steel measuring surfaces for preventing damage or wear against abrasive substances and laboratory conditions. They feature heavy-duty slide and bar arrangement for durability and slide lock for locking the caliper in position for transferring measurements. These digital calipers have a rechargeable battery port for easily charging the battery on spot.
