Mitutoyo digital caliper 150 mm IP67 Absolute 1.5V ABS/RD1.9 model 500-709-11/20

The Mitutoyo digital caliper 150 mm IP67 Absolute 1.5V ABS/RD1.9 model 500-709-11/20 is a precision measuring instrument designed for linear measurement tasks up to 150 mm. It features an Absolute (ABS) encoder that maintains a reference position without the need for zero setting after power on, and an IP67-rated body that provides protection against dust and temporary immersion in water. The caliper offers a clear digital readout for external, internal and depth measurements and is powered by a standard 1.5V battery for straightforward field and workshop operation.

Advantages

This caliper combines high measurement accuracy with robust environmental protection; the ABS encoder ensures reliable positional data while the IP67 rating reduces risks from coolant, chips and dust. The instrument’s compact 150 mm range is suitable for common inspection and machining checks, and the digital display delivers immediate, easily readable results. Its battery-powered design enables portable use without the need for external power, and the construction is made to withstand routine shop conditions.

Suitable for

• Dimensional inspection of machined parts
• Measuring external diameters, internal diameters and depths
• Quality control checks in workshops and production lines
• Field measurements where protection against water and dust is required

Key specifications

• Measuring range: 150 mm
• Encoder type: Absolute (ABS)
• Protection rating: IP67 (dust-tight and temporary immersion resistant)
• Power supply: 1.5V battery
• Measurement functions: external, internal and depth measurement
• Display: digital readout for direct reading of values

How to use

Before use, verify the battery is installed and the display powers on. For external measurements, close the jaws gently on the workpiece and read the value from the digital display. For internal measurements, use the upper jaws and ensure they contact the internal surfaces firmly but without excessive force. For depth measurements, extend the depth blade against the bottom surface and read the measurement. Use the absolute origin function to retain reference position after power cycles; zeroing can be performed as needed for comparative measurements.

Usage recommendations

Store the caliper in a clean, dry case when not in use, avoid prolonged exposure to liquids even though the instrument is IP67 rated, and replace the 1.5V battery promptly when display dimming or inconsistent readings appear. Clean measuring faces with a soft cloth before measurements and avoid shock or heavy impacts to maintain calibration.
