Spi K450 Electronic Caliper Gage 50mm External

Product Description

The SPI K450 is an electronic caliper gage designed for external groove measurements in precision metrology and quality control applications. It measures from 0 mm to 50 mm with a resolution of 0.02 mm and an accuracy of 0.04 mm, making it suitable for close-tolerance inspection work. The ball-to-ball contact point design allows the gage to seat reliably inside external grooves, delivering repeatable readings on machined components. Data output capability allows measurements to be transmitted directly to a connected device or SPC system for real-time process monitoring. Powered by a single 1.5V battery, the K450 is a self-contained handheld instrument.

The K450 is used in manufacturing, machine shop, and quality assurance environments where external groove dimensions must be verified to tight tolerances. Typical applications include inspection of snap ring grooves, retaining ring grooves, and similar external recesses on turned or machined parts. The ball-to-ball contact points are suited for grooves up to 30 mm deep and 30 mm wide. Licensed metrology technicians, QC inspectors, and machinists are the primary users of this instrument.

Key Features

• Measurement range of 0 mm to 50 mm for external groove inspection
• Resolution of 0.02 mm for fine measurement increments
• Accuracy rated at 0.04 mm
• Ball-to-ball contact point design seats positively in external grooves
• Data output port for integration with SPC software or digital readout systems
• Operates on a single 1.5V battery for portable, cordless use

Compatibility

Designed as an OEM-style electronic caliper gage for external groove measurement applications; compatible with standard data output collection systems that accept electronic gage signals.

Installation Notes

Installation and calibration should be performed by a qualified metrology technician or QC professional familiar with precision hand gages. Before use, zero the gage on a known reference standard appropriate to the measurement range. Keep contact points clean and free of chips or coolant residue, as contamination will affect accuracy. Store the gage in its protective case when not in use to prevent damage to the contact points and electronic components.
