3-Zone Thermal Shock Test Chamber

Welcome to our professional 3-Z one Thermal Shock Test Chamber page. As a reliable environmental testing equipment manufacturer, we provide high-quality three-box thermal shock test chambers that meet international standards, helping you evaluate the reliability and stability of your products under extreme temperature changes.

Product Introduction

Our 3-Zone Thermal Shock Test Chamber is designed with three independent zones: Hot Zone, Cold Zone, and Test Zone. Unlike traditional 2-zone basket-type models, our 3-zone structure keeps samples stationary in the test zone, realizing rapid hot and cold air switching through high-seal dampers. This design ensures zero mechanical vibration, avoiding damage to precision components and improving test accuracy—perfect for live testing and high-value precision samples.With advanced PID temperature control system and dual-stage cascade refrigeration technology, the chamber achieves rapid temperature switching (≤15s, ≤10s for high-end models) and stable temperature control, fully complying with IEC 60068-2-14, GB/T 2423.22, MIL-STD-810 and other international and national standards. It is widely used in electronics, automotive, semiconductor, aerospace, military, LED and other industries.

Core Features

Three Independent Zones: Hot Zone (RT+10℃~200℃), Cold Zone (-70℃~RT), Test Zone—samples stay stationary, zero vibration, suitable for precision and live testing.

Rapid Temperature Switching: ≤15 seconds (≤10s for high-end models), realizing instant hot-cold shock without mechanical movement of samples.

High Precision Control: Temperature uniformity ±1.0~1.5℃, fluctuation ±0.5℃, CFD-optimized air duct ensures uniform temperature distribution in the test zone.

Intelligent Operation: 7-inch LCD touch screen controller, support multi-stage program setting, data recording, curve display, USB export and remote monitoring.

Comprehensive Safety Protection: Equipped with over-temperature, over-pressure, phase loss, overload, door interlock and emergency stop functions, ensuring safe operation.

Multi-purpose & Customizable: Can be used as independent high-temperature aging, low-temperature storage or thermal shock test; customizable size (80L~1000L+), temperature range and additional functions.
