Hot box tester for the heat transfer coefficient (U-value) of exterior doors and windows with controlled hot and cold chambers.
Overview
It is used to test the thermal insulation performance (heat transfer coefficient) of building exterior doors and windows. The hot chamber is 1820 and the cold chamber is -20 to -10, with downward air velocity of about 3m/s. It complies with GB/T 16729-1997 and GB/T 8484-2008, with a separate control room and computer console.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Precision temperature control with PID regulation and over-temperature protection
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Doors and Windows Thermal Insulation Tester comply with?
A1: The Doors and Windows Thermal Insulation 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 Doors and Windows Thermal Insulation 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.
