Digital indicators overview
Digital indicators allow easy reading, gearless precision, with both Imperial and Metric Measurements. Digital indicators have the advantage of collecting measurement data and recording it and transmitting to a computer running statistical process control software. This process, known as SPC, also reduces the risk of the operator introducing recording errors. Dorsey offers the most popular styles of digital indicators to complement our gages. If your requirements are not met by selection below, please contact us for information on additional styles that we carry.
Style 1 Digital Indicators
