STARRETT 798A-12/300 Electronic Digital Caliper 0 To 12 In

Starrett 798A-12/300 electronic digital calliper is designed for precisely measuring the internal & external diameters or distances of objects in scientific & manufacturing facilities.

Working Mechanism:

• Starrett calliper features two sets of jaws that measure the diameters or distances related to workpieces.
• Once switched ON, these jaws are placed into the cavity that needs to be measured and are opened by sliding the measuring assembly.
• The digital display reads the distance between the measuring points of the object.
• The jaws of this calliper are then locked in position with a slide lock for measuring the value.

Features:

• Starrett electronic digital calliper 798A-12/300 features an easy-to-read LCD readout with high-contrast and zero-set, power & inch/mm control buttons.
• It is supplied with a plastic case to ensure proper storage.
• This unit has an induction-type linear encoder system for high accuracy.
• It provides IP67-rated protection against dust, dirt, coolants and water usually found in machining shops and automotive facilities.
• This model features wireless data transmission for transferring the data saved to electronic devices and computers.
• It can transfer data to devices in a range of 30 feet without any data loss.
• The calliper has hardened stainless steel measuring surfaces for preventing damage or wear against abrasive substances and laboratory conditions.
• It offers a measuring range of 0 - 12 inches (0 - 300 mm) with an accuracy of +/-0.001-inch (0.03 mm) and 0.0005 inch (0.01 mm) resolution.
• The product can turn Off automatically after 30 minutes, when not in use.
• It comes with a heavy-duty slide and bar arrangement for durability.
• The slide lock is ideal for locking the calliper in position for transferring measurements.
• The unit has a rechargeable battery port for easily charging the battery on spot.

Compatible Accessories:

• Starrett PT22431 Depth Attachment: It easily connects to the depth-rod end or measuring jaws of the tool by using just a screw and allows perpendicular entry into holes / grooves. This unit is used for measuring the depth of the workpiece.
• Starrett PT26151 Distance Attachment: This centre distance attachment features conical points and is used for measuring the centre distance between centre punched locations or holes on the workpieces.

Standards and Approvals:

• DIN 862

Frequently Asked Questions:

Q. How accurate are digital callipers?

A. Digital callipers are highly accurate instruments critical for taking measurements in laboratories and scientific facilities. These digital callipers are accurate up to 0.0005 inches of the workpiece's inside & outside diameter & depth. Additionally, these instruments can also convert the measured value to the desired unit system.

Q. What is the tolerance value for digital callipers?

A. 0.002 inches.

Q. What measurements can be obtained from callipers?

A. Object thickness, outside diameter, step distance, inside diameter and hole depth.

Q. How to install this Starrett digital calliper?

A.

• Starrett callipers feature a moving slider arrangement for measuring the distances between the object.
• The jaws of these callipers are placed into the object cavity and moved until both of the jaws hit the workpiece edges.
• The slider lock is engaged to lock the slider in place for observing the measured reading.
• Digital callipers can take accurate measurements using a series of capacitance sensors that run along the length of the beam of the calliper.
