Intelligent Air Permeability Tester (QR-ZTY)

Product Introduction

The Intelligent Air Permeability Tester (ZTY) is a high-precision instrument designed to measure the permeability of raw sand and molding (core) sand. Permeability refers to the ability of sand to allow gases to pass through—a critical parameter that directly impacts casting quality. Poor control of sand breathability can lead to common casting defects such as porosity, blowholes, or choking.

This advanced tester adopts a color LCD touch-screen interface with a Chinese operating system, high-precision sensors, and fully automated control. It provides real-time curve display, data storage, result querying, and printing functions, making it ideal for modern foundries, quality inspection centers, research institutions, and teaching laboratories.
