The INSIZE 3507-25 Digital Indicating Micrometer is a high-precision digital measuring instrument designed for accurate measurement and inspection of outside dimensions from 0–25mm. It combines a 0.002mm micrometer head graduation with a highly sensitive 0.1µm digital indicator resolution, providing detailed measurement information for precision machining and quality-control applications. The instrument features an absolute encoder, built-in Bluetooth, IP54 protection, carbide measuring faces, and digital/analog reading. Its data-output capability allows measurements to be transmitted to compatible computers and mobile devices for inspection and documentation.
Key Features
1. Precise 0–25mm Measuring Range
The 3507-25 provides a 0–25mm measuring range, making it suitable for precision measurement of small shafts, components, machined parts, and other outside dimensions in engineering and manufacturing applications.
2. Fine 0.002mm Micrometer Graduation
The micrometer head provides 0.002mm graduation with a specified micrometer-head accuracy of 3µm. The digital indicator provides a 0.1µm resolution and ±1µm indicator accuracy, supporting detailed dimensional inspection.
3. Built-In Bluetooth & Data Output
The 3507-25 features built-in Bluetooth for wireless data transmission. Measurements can be transferred to Excel, Word, TXT files, and compatible Android/iPhone applications. USB Type-C data transmission is also supported.
4. Digital & Analog Reading
The instrument provides both digital and analog reading, while its absolute encoder retains the original measurement position after power is switched off. This supports convenient operation and repeatable inspection workflows.
5. Durable Precision Measuring Design
The 3507-25 features carbide measuring faces, a 3mm measuring stroke, IP54 protection, and rechargeable lithium-battery operation. Battery operation provides up to approximately 20 hours of continuous working, with Bluetooth transmission potentially reducing operating time.
