The Brown & Sharpe Tesa 00530224 electronic caliper has rounded measuring faces with knife-edge jaws for accurate inner diameter (ID) and outer diameter (OD) measurements. It has a magnetic, stainless steel scale with 0.01mm/0.0005" gradient spacing and uses both inch and metric measuring systems. It is for use in applications where the highest accuracy is required, especially in scientific research and in industries where parts must fit exactly.

The 00530224 electronic caliper has 7-mm LCD characters, idle mode after 10 minutes, automatic switch-off after two hours, floating zero, display lock, and inch/metric conversion. Range is 0 - 500 mm/0 - 20" and resolution is 0.01 mm/0.0005". Jaw tip width is 10 mm and inside jaw depth is 150 mm. Maximum displacement speed is greater than 1.8 m/s, digital interface is RS232 opto-coupled, mono, and bi-directional, and autonomy is 1.5 a (2000 h/a). Operating temperature range is 10 - 40 degrees C and recommended storage range is -10 - 60 degrees C at 100% maximum relative humidity. Electromagnetic compatibility is EN 50081-1 and EN 50082-1. This caliper is Ingress Protection (IP67) certified (IEC 60529) for protection from dust and temporary submersion in water and meets Deutsches Institut für Normung (DIN) 862 standards for quality assurance. It works with one CR 2032 3V lithium battery (optional accessory 01961000, sold separately).

Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, machining, manufacturing, carpentry, and medicine. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers all give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The dial caliper is used also for measuring size differential between two objects. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices.

Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, played a key role in setting industrial standards in the United States. Brown & Sharpe was acquired by Hexagon Metrology in 2001 and is headquartered in North Kingstown, RI.
