Starrett 795MEXFL-50 LCD Outside Micrometre, IP67, Friction Thimble, Lock Nut, Carbide Faces, 25-50mm Range, 0.001mm Graduation, +/-0.003mm Accuracy, RS-232 Output

The Starrett 795M/796M 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, and a Vernier scale in metric units for taking precise outside diameter (OD) measurements. The micrometre has an Ingress Protection 67 (IP67) rating, which means that components are resistant to debris and to submersion in liquid under standard conditions for up to 30 minutes. 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. Depending on the model, it may have Statistical Process Control (SPC) data output to transmit results to a computer or external device through an interface cable (sold separately).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.
