Spi K330 Electronic Caliper Gage 30mm External

Product Description

The SPI K330 is an electronic caliper gage designed for external groove measurements in precision metrology and quality control applications. It uses a ball-to-ball contact point configuration to measure groove widths accurately, with a maximum measurement range of 30 millimeters and a resolution of 0.02 millimeters. The gage includes a data output feature, allowing readings to be transmitted to a PC or data collection system for documentation and SPC workflows. Powered by a single 1.5-volt battery, the K330 is a compact, self-contained instrument suited for shop floor or inspection room use by machinists, quality technicians, and tool-and-die professionals.

The K330 is used in applications where external groove width must be measured with consistent repeatability. Typical use cases include incoming inspection, in-process checks on turned or milled parts, and final inspection of machined components. The ball-to-ball contact geometry allows the gage to seat properly in grooves and undercuts where flat-face contacts would not make reliable contact. This instrument is appropriate for job shops, production floors, and metrology labs handling precision mechanical components.

Key Features

• External groove measurement with ball-to-ball contact points for reliable seating in grooves and undercuts
• 30 mm maximum measurement range with 0 mm minimum for full-range groove inspection
• 0.02 mm resolution for fine measurement discrimination
• 0.02 mm accuracy per manufacturer specification
• Data output port for connection to PC or SPC data collection systems
• Single 1.5-volt battery operation for portable, standalone use

Compatibility

Designed as an OEM-style electronic caliper gage for external groove measurement tasks on precision machined parts; verify that the 30 mm maximum range and ball-to-ball contact geometry suit the specific groove dimensions of your application before installation.

Installation Notes

Setup and use of this gage should be performed by a qualified machinist or metrology technician familiar with caliper-style gaging instruments. Before use, zero the gage on a calibrated reference standard to confirm accuracy. Keep contact points clean and free of chips, coolant, and debris, as contamination will affect measurement repeatability. Handle contact points with care to avoid impact damage, which can alter the contact geometry and invalidate calibration.
