What are Mahr Calipers?

Mahr calipers are precision measurement tools manufactured by Mahr, a globally recognised brand in metrology equipment. Designed for engineering applications where accuracy is critical, these calipers deliver reliable performance in both workshop and inspection settings. Whether used in manufacturing, quality control or R&D, Mahr calipers provide engineers and technicians with consistent and highly repeatable measurements.

For example, in aerospace component inspection, a Mahr digital caliper can verify part dimensions down to fractions of a millimetre, ensuring compliance with stringent tolerance requirements.

How Mahr Calipers Work

Mahr calipers operate by using a pair of precision-ground jaws to measure the external, internal and depth dimensions of a workpiece. Available in both vernier and digital formats, these calipers provide accurate readings in either metric or imperial units. Models with USB data readout allow direct transfer of measurements into quality control software, improving workflow efficiency.

Features such as IP67 ingress protection safeguard the tool against dust and coolant, making it suitable for demanding industrial environments.

Materials Mahr Calipers Are Made From

Accu's range of Mahr calipers are constructed from hardened stainless steel for durability and corrosion resistance. This ensures wear resistance, long-term accuracy and reliable performance in workshop or field conditions.

Sizes and Types of Mahr Calipers Available

The standard size available is 150 mm / 6 inch, which meets the requirements of most engineering and manufacturing applications. Other optional features include:

• Pocket-sized: Compact and portable for fieldwork.
• IP67-rated: Resistant to dust and liquid ingress for harsh environments.
• USB data readout: Direct digital measurement export via USB for quality control processes.
• Cylindrical depth blade: Ideal for slot and groove depth measurements.
• Rectangular depth blade: Suitable for broader depth measurement applications.

FAQs

Q: Where are Mahr calipers made?

A: Mahr calipers are manufactured by Mahr, headquartered in Germany, with production facilities in various locations worldwide.

Q: Are Mahr calipers accurate?

A: Yes. Mahr calipers are engineered to deliver high precision, with many digital models achieving resolutions as fine as 0.02mm.

Q: What’s the difference between a Mahr digital caliper and a Mahr vernier caliper?

A: Digital calipers display measurements electronically and often include data output capabilities, while vernier calipers use a manual scale and are more traditional in design.

Q: Can Mahr-branded calipers be used in wet environments?

A: Yes. IP67-rated models are designed to resist dust and coolant ingress, making them ideal for workshop use.

Q: Do Mahr Calipers require calibration?

A: Like all precision instruments, periodic calibration ensures optimal accuracy and compliance with quality standards. The digital variant has an adjustable zero point allowing for a degree of calibration each time a new zero point is measured. Visit our how to use a caliper guide to learn more.
