Electronic digital indicators are designed to record data in process control applications, readily transferable to PC while mitigating any chances of parallax errors. Raptor Supplies offers a vast selection of electronic digital indicators from brands like Brown & Sharpe, Johnson, Mahr-Federal, Mitutoyo, Starrett, Tesa and Westward. Johnson designs digital indicators with an accuracy of 0.008 mm. These hard case indicators can directly transfer data to print and feature on-the-go inch to mm toggle function. They are powered by a 3 V lithium ion battery and equipped with a 360-degree rotating bezel which can operate in both positive and negative directions. Mitutoyo digital test indicators accurately measure small linear distances in inches and millimetres. They provide relative and absolute measurements with preset upper and lower limits. These indicators feature an easy to read LCD with toggle buttons, with selected models having a calibration certificate.
