Digital Caliper 150 mm IP67 Coolantproof, No name model 500-706-20, 1.5V ABS

Digital caliper with a 150 mm measuring range, model 500-706-20 by No name, designed for workshop and inspection use where wet or contaminated environments are possible. The instrument measures external dimensions, internal diameters and depths with a clear digital readout. The caliper features coolantproof protection to IP67 and an ABS housing, powered by a 1.5 V battery for portable, ready-to-use operation.

Advantages

The IP67-rated protection ensures reliable performance in the presence of water and coolant splashes, preventing ingress that can affect accuracy. The ABS housing provides a lightweight yet durable enclosure that resists chemicals commonly found in workshop environments. The digital display offers fast, easy-to-read measurements in metric or imperial units and reduces reading errors compared with analog scales.

Suitable for

• External diameter and thickness checks on machined parts
• Internal diameter inspection of bores and holes
• Depth measurements of slots, recesses and steps
• Maintenance tasks in wet or coolant-exposed environments
• Quality control and inspection in small workshops and industrial settings

Key specifications

• Measuring range: 0–150 mm
• Protection rating: IP67 (dust tight and protected against temporary immersion)
• Housing material: ABS plastic
• Power supply: 1.5 V battery
• Measurement functions: external, internal and depth measuring
• Display: digital readout with unit selection (metric/imperial)

How to use

Before use, ensure the battery is installed and the measuring faces are clean and free of debris. Power on the caliper and zero it at the fully closed position. For external measurements, place the jaws around the object and read the value from the digital display. For internal measurements, open the internal jaws inside the bore and read the display. For depth measurements, extend the depth rod into the feature and read the value. After measuring, wipe the caliper dry if wet and store it in a protective case or location to avoid impact damage.

Usage recommendations

Regularly clean measuring surfaces and avoid prolonged immersion despite the IP67 rating; rinse and dry the tool after exposure to coolant or water. Replace the 1.5 V battery when display dimming or inconsistent readings occur. Calibrate periodically according to your workshop quality procedures to maintain measurement accuracy.
