Upright forced-air low-temperature freezer with microcomputer control for storing bitumen, soil specimens, samples and reagents in the laboratory.
Overview
This upright forced-air low-temperature constant-temperature refrigerator is used in labs, hospitals and pharmacies for the low-temperature storage of samples, reagents, vaccines and bitumen/soil specimens under controlled temperature. It uses microcomputer control with NTC sensor and digital display; a double-layer tempered glass door allows observation and is electrically heated to prevent condensation. Audible/visual alarms cover high/low temperature, power failure, sensor fault and door ajar. The refrigeration system uses an international-brand compressor and CFC-free refrigerant with forced-air cooling and automatic defrosting, giving good temperature uniformity and stability for constant-temperature conditioning of bituminous and geotechnical specimens.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Large LCD display showing real-time test parameters and results
• 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 Upright Low-Temperature Laboratory Freezer comply with?
A1: The Upright Low-Temperature Laboratory Freezer 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 Upright Low-Temperature Laboratory Freezer 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.
