V3/V5 rapid freeze-thaw machine for concrete durability, 2.5–4 h cycles, specimen center −18±2 °C to 5±2 °C. Request a quote.
Overview
Freeze-thaw cycle period is 2.54 hours, with thawing time 1/4 of the cycle; at the end of freezing the specimen center temperature is -182, and at the end of thawing is 52. Cooling time is 1.52.5h, heating 1.01.5h; temperature difference between center and surface is <28; standard cycles are 300+. It uses an imported compressor, featuring low noise, power saving and compact size, and has a national patent.

FAQ
Q1: What standards does the V3/V5 Concrete Rapid Freeze-Thaw Testing Machine comply with?
A1: The V3/V5 Concrete Rapid Freeze-Thaw Testing Machine 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 V3/V5 Concrete Rapid Freeze-Thaw Testing Machine 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.
