High and Low Temperature Test Chamber

Category Environment Test Machine

Haida equipment high and low temperature test chambers specialize in simulating extreme heat, cold, and rapid temperature change environments to evaluate product performance, reliability, and stability under harsh thermal conditions.Temperature Range:-70℃ ~ +150°℃ Humidity Range: 20%RH~98%RH

Product Description

This series is used for heat resistance, cold resistance, dry resistance and moisture resistance of various materials. It is suitable for testing the quality of electronic, electrical appliance, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products.

Linear temperature ramp rates from 5°C/min to 15°C/min significantly accelerate testing cycles.
Advanced airflow design ensures uniform temperature distribution throughout the chamber for consistent results.
Multiple safety protections, including independent over-temperature protection and compressor delay, ensure worry-free operation.
It also complies with IEC 60571, NB/T 31004, GJB 150, IEC, MIL and other test standards.
