This constant temperature and humidity test chamber (GC-TH series) maintains stable humiture to evaluate material durability. With a Tecumseh refrigeration system, SUS#304 inner box, and double-layer insulated door, it prevents temperature leakage. It meets GB/T2423 and IEC 60068 standards, suitable for testing electronics, food, building materials, and auto parts. The self-developed LCD controller shows real-time data, and built-in universal wheels enable easy movement. Ideal for factories, inspection bureaus, and research labs.

Product Description
The Constant Temperature And Humidity Test Chamber (Models: GC-TH-150, GC-TH-800, GC-TH-1000) is a large-capacity environmental testing solution tailored for bulk or oversized samples. With inner box volumes ranging from 150L to 1000L (e.g., 1000mm×1000mm×1000mm for GC-TH-1000), it maintains stable temperature (-40~150℃) and humidity (20~98% RH) to simulate real-world conditions, making it ideal for testing large components or multiple samples simultaneously. Key advantages include a split humidification cylinder (easy maintenance), Taiwan-imported stainless steel fin heaters (uniform heating), and a fin-type condenser with Taiwan cooling fan (efficient heat dissipation). It complies with 14 international standards (e.g., GB/T2423.1, IEC60068-2-1), ensuring test results are recognized globally.
Large-Capacity Design: Multiple volume options (150L/800L/1000L) accommodate oversized samples like auto dashboards, large electronic enclosures, or bulk building materials. Two adjustable stainless steel shelves maximize space utilization.
Energy-Efficient Refrigeration: Adopts environmentally friendly refrigerants (R404A/R23 from Honeywell) and multi-stage automatic load adjustment technology, reducing energy consumption while maintaining rapid cooling (1℃/min average).
User-Friendly Details: Three-layer vacuum glass viewing window (with LED lighting) allows clear observation of samples without temperature leakage. Removable built-in water tank (with automatic water supply pump) simplifies cleaning and refilling.
This chamber is essential for industries requiring large-scale testing:
Automotive & Aerospace: Testing full-size auto parts (e.g., seats, door panels) or aerospace components for resistance to extreme climates.
Building Materials: Evaluating moisture absorption and thermal stability of bulk materials like insulation boards or flooring.
Electronics Manufacturing: Conducting reliability tests on large electronic assemblies (e.g., server racks, industrial control panels) under constant humidity.
Inspection Bureaus: Performing compliance testing for large batches of products (e.g., household appliances, toys) to meet national or international standards.
