The MITUTOYO 293-240-30 Coolant Proof Digital Micrometer (0–25mm) is a high-performance IP65-rated Digimatic micrometer engineered for precision measurement in harsh workshop environments.
Designed with coolant-proof protection (IP65), this micrometer can operate reliably in environments exposed to oil, dust, and coolant, making it ideal for CNC machining and industrial use.
It offers a measurement range of 0–25mm with an ultra-fine resolution of 0.001mm (1 micron), ensuring extremely accurate and repeatable measurements.
The ABS (Absolute) scale technology allows the origin to be set once and retained, eliminating repeated zero setting and improving efficiency.
Equipped with a ratchet stop, the tool ensures consistent measuring force, improving repeatability across measurements. Its carbide-tipped measuring faces provide durability and long-term accuracy.
The large LCD display ensures clear readings, while the anti-slip frame design offers better grip for one-handed operation in industrial conditions.
