Caliper Tesa 00530321 150 Digits IP67 3V — digital caliper 150 mm, IP67 protection, 3V battery

The Tesa 00530321 150 Digits IP67 3V digital caliper is a precision measuring instrument with a 150 mm measuring range and a clear digital display. Designed for external, internal and depth measurements, this caliper delivers straightforward metric readings powered by a 3V battery. Its IP67 protection class provides resistance to dust ingress and temporary immersion in water, making it suitable for humid or partially wet workshop environments where reliable, compact measurement is required.

Advantages

This Tesa digital caliper combines a compact 150 mm capacity with a digital readout for fast, accurate measurements without manual interpolation. The IP67 rating offers enhanced protection against dust and water exposure compared with standard calipers, reducing the risk of damage in damp conditions. Battery-powered operation with a common 3V cell ensures easy replacement and consistent performance. The instrument is suitable for repeated use in inspection and production settings due to its robust design and simple operation.

Suitable for

• External dimensional checks of small parts and components
• Internal diameter measurement of bores and recesses
• Depth gauging of slots, steps and holes
• Workshop use where moisture resistance is needed
• Quality-control sampling and routine inspections

Key specifications

• Measuring range: 0–150 mm
• Display: digital readout for metric measurements
• Protection class: IP67 (dust-tight and temporary immersion resistant)
• Power supply: 3V battery
• Measurement functions: external, internal and depth measurements

How to use

Turn the caliper on using the power button, zero the display at the fully closed jaws if necessary, then place the jaws or depth rod against the part to be measured. For external measurements, close the jaws around the outside of the component until they contact both faces; for internal measurements, use the internal jaws and open them until they contact the bore; for depth measurements, extend the depth rod into the hole or slot and read the value on the digital display. Replace the 3V battery when the display indicates low power and store the caliper in a clean, dry place to maintain its IP67 protection over time.

Usage recommendations

Handle the caliper with care to avoid strong impacts and contamination of the measuring surfaces. Before critical measurements, clean contact surfaces and perform a zero check. Although the instrument is IP67-rated, avoid prolonged submersion and dry it thoroughly after exposure to liquids. Use a fresh 3V battery for stable readings and follow routine calibration or verification procedures appropriate to your quality-control system.
