Mitutoyo 0 - 25 mm Digital Micrometer With Ratched Stop & SPC Data Output (IP65 Coolant-Proof), 293-230-30

A Mitutoyo waterproof digital micrometer suitable for use in the presence of coolant or cutting oil. The highly stable frame incorporates a heat shield to preserve accuracy over extended measuring sessions. A ratchet thimble guarantees repeatable measurement. Digimatic data output.

This prevents an instrument from giving an erroneous reading. Also, when the battery voltage drops to a certain level, the low-battery-voltage alarm annunciator appears well before the micrometer becomes unusable. This IP65 micrometer offers outstanding accuracy, with and without data output, is highly robust, and offers the following benefits:

• Oil-resistant material used for all plastic parts
• Extraordinary battery life of 2.4 years*
• Excellent resistance against water and dust enables this micrometer to be used in machining situations that include splashing coolant fluid.
• World's highest-performing micrometer overall.
• Ergonomic anti-slip frame cover and front panel for more comfortable hand-held measurements.
• Ratchet thimble provides better operability for one-handed operation.
• Models equipped with a Digimatic output port can form part of statistical process control or a networked measurement system.
• Interface Input Tools are available that enable the conversion of measurement data to keyboard signals that are then directly inputted to cells in off-the-shelf spreadsheet software such as Excel. 
• Two types of constant-force devices are available: Ratchet Stop and Ratchet Thimble.

Functions:

• Origin point setting (ABS measurement system): Resets the ABS origin at the current spindle position to the minimum value of the measuring range and switches to ABS mode.
• Zero-setting: A brief press on the ZERO/ABS button sets the display to zero at the current spindle position and switches to the incremental (INC) measuring mode. A longer press resets to the ABS measuring mode.
• Hold: Pressing the HOLD button freezes the current value in the display. This function is useful for preserving a measurement in situations of poor visibility where the instrument must be moved away from the workpiece before the reading can be recorded.
• Data output: Models equipped with this function have an output port for transferring measurement data to a Statistical Process Control (SPC) system. *1 Only models with the data output function 
• Auto power ON/OFF: The reading on the LCD disappears after this instrument is idle for about 20 minutes, but the reading and measurement mode is retained. Turning the spindle causes the reading to reappear.
• Error alarm: In case of an overflow on the LCD or a computing error, an error message appears on the LCD, and the measuring function stops.
• Function lock: This function allows the ORIGIN (origin point setting) function and the ZERO (zero-setting) function to be locked to prevent these points from being reset accidentally.
