Mitutoyo 550-341-20 Electronic Caliper 300mm IP67

Product Description

The MITUTOYO 550-341-20 is a digital electronic caliper designed for precise dimensional measurement in industrial and workshop environments. It covers a measurement range of 0 to 300mm with a resolution of 0.01mm and an accuracy of 0.03mm. The caliper carries an IP67 rating, making it resistant to dust and temporary water immersion — suitable for use in production floors and machine shops where coolant or debris is present. Built from stainless steel with stainless steel jaws measuring 76.2mm in length, it is built to handle the demands of regular trade and manufacturing use. An SPC output port allows direct data transfer to a computer or data collection system for statistical process control workflows. Licensed metrologists, machinists, and quality control technicians are the primary users.

The 550-341-20 is suited for both inside and outside diameter measurements across a broad range of parts. The inside jaw capability supports measurements up to 12 inches in maximum inside diameter. The 12mm nib size accommodates measurement in confined features. This caliper is appropriate for light manufacturing, tool and die work, quality inspection, and general precision layout tasks in industrial or trade environments. It is a single-unit package with no depth rod included.

Key Features

• IP67 dust and water ingress protection for use in demanding shop environments
• 0.01mm resolution with 0.03mm accuracy across the full 0 to 300mm range
• SPC output for direct connection to data collection and statistical process control systems
• Stainless steel construction with 76.2mm jaw length for durability and measurement reach
• Inside jaw capability for inside diameter measurements up to 12 inches
• 12mm nib size for access to narrow grooves and recessed features

Compatibility

Designed as an OEM-style precision measuring instrument for use with standard SPC-compatible data collection interfaces and measurement workstations requiring a 0 to 300mm digital caliper with IP67 protection.

Installation Notes

Electronic calipers require no installation in the traditional trade sense but should be zeroed before use according to the manufacturer calibration procedure. Handle the jaws with care to avoid impact damage that can affect calibration. Keep the SPC output port clean and dry when not connected to prevent corrosion, even given the IP67 rating. Battery replacement and periodic recalibration should follow the manufacturer service schedule to maintain measurement accuracy.
