Starrett 733MEXFLZ-300 LCD Outside Micrometre, Friction Thimble, Lock Nut, Carbide Faces, 275-300mm Range, 0.001mm Graduation, +/-0.007mm Accuracy

The Starrett 733M series LCD outside micrometre has a digital single-value LCD readout that displays in inch and metric units with resolution to 0.00005” (0.001mm) for outside diameter (OD) measurement, a Vernier scale in metric units for taking precise outside diameter (OD) measurements, and Statistical Process Control (SPC) data output to transmit results to a computer or external device. The output jack transmits SPC results to a computer through an interface cable (sold separately).The micrometre's electronic microprocessor can preset, hold, or limit measurement at any position, as well as set a temporary zero position and return to a true zero reading. An automatic off function helps preserve battery life when the unit is not in use. The micrometre's frame has a black wrinkle finish that helps resist rust and reduce glare. A friction thimble mechanism helps provide uniform pressure for precise, repeatable measurement. The Vernier scale on the thimble and sleeve has a satin chrome rust- and glare-resistant finish. The spindle and anvil have flat, micro-lapped measuring faces for accuracy and are carbide-tipped for wear resistance. A knurled ring-type lock nut helps provide secure locking of the measurement position. The micrometre includes, and is powered by, a single CR2032 lithium cell battery.
