Key Features
1. 75–100mm Measuring Range
The 3507-100 provides a 75–100mm measuring range, making it suitable for inspecting medium-sized shafts, machined components, precision parts, and other workpieces requiring accurate dimensional measurement.
2. High-Resolution Digital Indicator
The micrometer head provides 0.002mm graduation, while the digital indicator offers 0.1µm resolution with a ±0.04mm indicator range. The micrometer head accuracy is 3µm and digital indicator accuracy is ±1µm, with 0.3µm repeatability.
3. Built-In Bluetooth Data Output
The 3507-100 features built-in Bluetooth for wireless measurement-data transmission. Bluetooth transmission can reach up to approximately 10m, and the instrument also supports USB Type-C connectivity for data transfer.
4. Digital & Analog Reading
The instrument supports both digital and analog measurement reading. Its absolute encoder retains the original measurement data after power-off, while functions include zero setting, mm/inch conversion, tolerance settings, display settings, and data transmission.
5. Professional Precision Construction
The 3507-100 features carbide measuring faces, a 3mm measuring stroke, IP54 protection, and compliance with DIN 863-3. It uses a rechargeable lithium battery with up to approximately 20 hours of continuous operation, depending on Bluetooth usage.
