Multi-function hardness tester with color display

Phase II Multi-function hardness tester with color display for portable hardness testing of metal parts

This product is most relevant to field inspectors, fabrication shops, foundries, and QA teams who need fast instrument-based checks outside a full laboratory setup. Good use cases include incoming inspection, maintenance work, shop-floor verification, and reporting on parts that are too large, too installed, or too numerous for slower bench methods.

High-Speed Hardness Testing for Large Components

The updated PHT-1900 hardness tester is designed to quickly and accurately measure large hard components using the reliable Leeb rebound technique.

Advanced Display & Features

Its clear, color display highlights advanced features unique to this portable hardness tester, including auto-probe detection, automatic direction recognition, and both single and multi-point calibration. With lightning-fast test speeds, built-in memory, and USB output, the PHT-1900 is an essential tool for any professional workshop.

Portable Hardness Tester Phase II: PHT-1900 – Rockwell, Brinell, Vickers

The PHT-1900 easily converts readings to popular hardness scales, including Rockwell, Brinell, Vickers, Shore, and more.

The Hardness Tester with Color Display – Multi-Function is widely used by manufacturing engineers, metallurgists, and quality control inspectors to measure the hardness of metal components directly on site. Portable hardness testers are designed to evaluate large or installed parts such as castings, forgings, pipelines, and machinery components without removing them from service, allowing fast verification of material strength and heat-treatment quality during production or maintenance inspections. Modern portable testers can automatically convert results between common hardness scales such as Rockwell, Brinell, Vickers, and Shore, supporting standardized materials testing in industrial environments.

Professionals value multi-function hardness testers for their color display interface, automatic probe recognition, and onboard memory that simplify measurement and documentation during field inspections. Compared with traditional bench-top hardness testers, portable digital instruments provide faster testing, on-site measurements, and automated data storage, helping improve efficiency and traceable quality control in machining, metal fabrication, maintenance, and materials inspection workflows.

The Hardness Tester with Color Display – Multi-Function is widely used by manufacturing engineers, metallurgists, and quality control inspectors to evaluate the hardness of metal components directly on site. Portable hardness testers based on the Leeb rebound method allow technicians to test large or installed parts such as castings, forgings, pipelines, and heavy machinery without removing them from service, enabling fast verification of material strength and heat-treatment quality during inspection and maintenance programs. Instruments of this class automatically convert readings to common hardness scales including Rockwell, Brinell, Vickers, and Shore, helping standardize material testing across industrial environments as described in technical documentation for portable hardness testing systems from Phase II portable hardness tester specifications.

Professionals value multi-function hardness testers for their color display interface, automatic impact device recognition, and built-in statistical analysis of measurements. Portable instruments can automatically calculate average, minimum, and maximum hardness values while storing multiple measurement groups for later analysis or USB data transfer, improving traceability and efficiency in industrial quality control workflows. These features make portable digital hardness testers particularly useful in machining, metal fabrication, maintenance inspection, and laboratory materials verification programs.
