QFZ adhesion tester that grades coating adhesion by the circle (spiral scratch) method, with manual and electric operation.
Overview
The QFZ QFZ Coating Adhesion Tester is designed according to GB/T 1720. It evaluates the adhesion of a coating to its substrate by the integrity of the coating within a spiral scratch, expressed in "grades". It offers both manual and electric operation; in electric mode it automatically indicates when the coating is scratched through to the substrate, featuring accurate and convenient operation.

FAQ
Q1: What standards does the QFZ Coating Adhesion Tester comply with?
A1: The QFZ Coating Adhesion Tester is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the QFZ Coating Adhesion Tester be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
