The Brown & Sharpe 00590304 Twin-Cal IP67 series electronic calipers has a 0 to 8"/0 to 200mm measuring range with 0.0005"/0.01mm resolution and 0.001"/0.03mm accuracy for obtaining outside, inside, step, and depth dimensions for a variety of precision measurement uses. The LCD has 0.43" high digits and its function buttons control on/off, zero-set, inch/mm conversion, mode, and data send. It permanently stores the zero-set position in Absolute mode, which saves time between measurements. A knurled clamping screw locks the slide to save a measurement. The stainless-steel frame and slide are durable and corrosion resistant, and the jaw faces are precision-ground for measuring accuracy. It has a thumb wheel slide control and a square depth rod. The data output port allows connection to a computer with an optional TESA TLC cable (sold separately) or an optional wireless system using a TESA TLC-Twin wireless station (sold separately). The calipers meet International Organization for Standardization (ISO) 13385-1 dimensional standards and it is Ingress Protection rated IP67 for protection against dust and liquids. It comes with a lithium battery and a fitted storage case. The electronic calipers is suitable for applications such as quality control for machined parts.

Digital calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. A pair of jaws attached to a long beam with a marked scale is used to take inside, outside, and step measurements. An additional depth probe slides along the beam to take depth measurements. One jaw is fixed to the end of the scale, while the other jaw slides along it with gearless precision to take measurements. The reading is electronically generated and displayed on a digital, high-resolution screen as a single value. Digital calipers can take differential measurements, which are used to determine the difference in measurements between two objects, by zeroing the display at any point along the scale. Some digital calipers can switch between standard and metric units, and some can output readings to a computer or printer for recording measurements. Compared to dial calipers, digital calipers provide measurements that are faster, easier, and more error-free, but they are more fragile mechanically and electronically, and do not resist coolant well. Vernier calipers are more durable than digital calipers because they do not have internal moving parts, but they can be more difficult to read. Digital calipers are commonly used in fields such as metalworking, mechanical engineering, machining, carpentry, and medicine.
