Spi 20-232-5 Electronic Thickness Gage Through Coating

Product Description

The SPI 20-232-5 is an electronic thickness gage designed for non-destructive measurement of material thickness, including measurements taken through coatings without requiring removal of paint, plating, or other surface layers. The steel anvil face provides a durable, stable contact surface for repeatable readings. With an accuracy of 0.0015 inches, this gage delivers precise measurements suitable for quality control and inspection work in fabrication shops, HVAC manufacturing, and mechanical service environments. It is used by metrologists, quality technicians, and trade professionals who require reliable dimensional verification on coated or uncoated workpieces.

This gage is well suited for applications where coating integrity must be preserved and surface removal is not practical. Typical use cases include measuring sheet metal thickness in HVAC duct fabrication, verifying plating depth on components, and inspecting coated pipe or tubing wall thickness. The through-coating capability makes it particularly useful in maintenance and inspection scenarios where parts cannot be stripped before measurement.

Key Features

• Through-coating measurement capability eliminates the need to remove paint or plating before gauging
• Steel anvil face for durability and consistent contact during repeated measurements
• Accuracy of 0.0015 inches for precise dimensional inspection
• Electronic readout for fast, direct digital display of measurements
• Compact form factor at approximately 2.91 inches long, 1.3 inches wide, and 5.9 inches tall

Compatibility

Designed as a standalone electronic thickness gage suitable for use on a wide range of flat and curved workpieces where ultrasonic or eddy-current through-coating measurement is required.

Installation Notes

This gage is a handheld measurement instrument and does not require installation. Calibration verification against a known standard should be performed before use and at regular intervals per your shop or quality system requirements. Handle the steel anvil with care to avoid nicks or contamination that could affect measurement accuracy. Refer to the manufacturer documentation for probe coupling requirements and surface preparation guidelines appropriate to the material being measured.
