Our programmable temperature and humidity test chamber (GC-TH-80/100/225/400) simulates high/low temperature and humidity environments to test material performance—like heat/cold resistance of rubber, plastic, and electronics. It features a French Tecumseh compressor, SUS#304 inner box, and self-developed LCD controller for multi-segment programming. Compliant with GB, IEC, and GJB standards, it’s ideal for quality control in electronics, auto parts, universities, and research institutes. Perfect for detecting fading, shrinkage, and strength changes.

Product Description
The Programmable Temperature And Humidity Test Chamber (Models: GC-TH-80, GC-TH-100, GC-TH-225, GC-TH-408) is a high-precision environmental simulation device designed to test material performance under extreme temperature and humidity conditions. It replicates high/low temperature (-40~150℃) and high/low humidity (20~98% RH) environments, enabling users to evaluate heat resistance, cold resistance, dry resistance, and humidity resistance of materials—critical for quality control in various industries. Key selling points include a French "Tecumseh" hermetic compressor (for efficient refrigeration), SUS#304 stainless steel inner box (corrosion-resistant and easy to clean), and an independently developed LCD controller (supports multi-segment programming). Unlike basic test chambers, this model offers fast (QUICK) or slope (SLOP) control for temperature and humidity, ensuring flexible adaptation to complex test scenarios.
Precise Environmental Control: Achieves temperature stability of ±0.5℃ and humidity stability of ±2% RH, with a resolution of 0.01℃ (temperature) and 0.1% RH (humidity). The balance temperature and humidity control system (BTHC) uses PID to match heating/humidifying output with energy loss, ensuring long-term stable operation.
Intelligent Operation: 7-inch color LCD touchscreen supports Chinese/English switching, real-time curve display of test parameters, and 120 program groups (1200 segments total) with 999 repeat cycles. Power-off memory function resumes tests automatically after reconnection.
Safety & Durability: Equipped with 8 protective devices, including compressor overpressure protection, water tank shortage alarm, and heating dry-burn protection. Double-layer insulated door with anti-sweat electric heater prevents condensation, while built-in universal wheels (with fixed screws) enable easy movement.
This chamber is widely used in quality control and R&D for:
Electronics & Electricals: Testing semiconductors, batteries, and household appliances to ensure performance under humid or extreme temperature conditions.
Automotive Industry: Evaluating auto parts (e.g., rubber seals, plastic components) for fading, shrinkage, or strength loss in high-temperature/humidity environments.
Academic & Research: Supporting experiments in universities and research institutes for materials science, chemistry, and building materials.
Food & Paper: Assessing shelf life of packaged food and moisture resistance of paper products to prevent degradation.
