Direct Reading Air Permeability Tester (QR-STZ)
The Direct Reading Air Permeability Tester (QR-STZ) is a precision instrument designed to measure the air permeability of moulding sand and core sand under both dry and wet conditions. It is an essential device for foundries, machinery manufacturers, and research laboratories aiming to ensure the quality and consistency of sand used in casting processes.
Electronic Frequency Modulation Motor: Ensures accurate and stable operation with variable speed regulation.
Direct Digital Display: Air permeability readings are displayed clearly on the instrument board for easy monitoring.
High Accuracy: Measures air permeability with an accuracy of ±1% full scale (FS).
Versatile Testing: Compatible with dry and wet sand samples, making it ideal for different industrial and laboratory conditions.
The QR-STZ is widely used in:
Foundries – For quality control of molding and core sand.
Machinery and Casting Industries – Ensures casting defects are minimized by checking sand permeability.
Scientific Research and University Labs – Supports studies in materials science and engineering.
Qualitative Inspection – Reliable tool for routine testing of sand permeability.
