Caliper NEO tools 150 mm stainless steel model 75-001

NEO tools stainless steel caliper 150 mm (model 75-001) is a precision manual measuring instrument designed for accurate linear measurements up to 150 mm. Made from corrosion-resistant stainless steel, the caliper provides clear vernier scale readings for external, internal and depth measurements. The robust construction and fine adjustment allow steady contact with measured surfaces, making it suitable for routine use in workshops, manufacturing, hobby projects and quality control tasks that require reliable dimensional checks.

Advantages

The stainless steel construction ensures resistance to rust and daily wear, while the finely machined jaws and depth rod offer consistent measurement contact. The vernier scale delivers direct, easy-to-read measurement values without batteries or electronics, and the compact 150 mm range provides a balance between portability and useful measuring capacity. The caliper’s stable slide and locking screw maintain set positions for repeatable measurements.

Suitable for

• External diameter and length measurements of small parts
• Internal diameters of holes and bores
• Depth measurements of recesses and grooves
• Inspection and quality control in small workshops and production lines
• DIY and hobby projects requiring precise linear measurement

Key specifications

• Measuring range: 0–150 mm
• Material: corrosion-resistant stainless steel
• Measurement types: external, internal, depth
• Scale type: vernier scale for direct reading
• Accuracy class: typical mechanical caliper tolerances suitable for workshop use
• Locking mechanism: adjustable locking screw
• Overall length: approx. 150 mm measuring capacity (compact design)

How to use

Position the object between the jaws to measure external dimensions, open the jaws inside a hole for internal dimensions, or extend the depth rod into a recess for depth measurement. Slide the movable jaw until it makes firm, even contact with the measured surface, then tighten the locking screw to hold the position if needed. Read the measurement from the vernier scale by aligning the main scale and vernier graduations, accounting for the vernier least count. Handle the caliper gently and avoid applying excessive force to ensure accurate readings.

Usage recommendations

Keep the caliper clean and dry after use; wipe with a soft cloth and apply a light machine oil film to steel surfaces for storage in humid environments. Avoid strong impacts and do not use the jaws as a lever. Periodically check calibration against gauge blocks or a reference standard, especially when used for quality control.
