1. High-Precision Temperature & Humidity Control (Core Feature)

• Wide Range of Adjustable Parameters:
  • Temperature: Typically covers -70°C to +180°C (standard models); specialized models (e.g., ultra-low temperature chambers) can reach -196°C (for cryogenic testing), while high-temperature models extend to +300°C (for industrial material testing).
  • Humidity: Generally adjustable from 10% RH (relative humidity) to 98% RH; low-humidity models (for electronics/metals) can achieve ≤5% RH, and some high-humidity models (for pharmaceuticals) maintain 99% RH without condensation.
• Strict Control Accuracy:
  • Temperature fluctuation: ≤±0.5°C (within the working range), ensuring no sudden temperature spikes/drops that distort test data.
  • Humidity fluctuation: ≤±2% RH, critical for scenarios like drug stability testing (where 1-2% RH deviations can affect shelf-life calculations).
• Rapid Temperature/Humidity Change Rates:
  • Supports "ramp" (gradual) or "shock" (rapid) transitions. For example, standard models achieve a temperature change rate of 1-5°C/min; high-speed thermal shock chambers can shift from -40°C to +80°C in ≤5 minutes (simulating extreme outdoor environment changes for automotive/aviation parts).

2. Customizable Chamber Design & Capacity

• Diverse Chamber Volumes:
  • Small benchtop models (50-200L): For tiny components (chips, capacitors) or lab-scale tests (e.g., pharmaceutical tablet stability).
  • Medium floor-standing models (500-2000L): For end products (smartphones, small appliances) or batches of materials (textile rolls, plastic parts).
  • Large walk-in chambers (10-100m³): For oversized items (automotive engines, solar panels, furniture) or full-system testing (e.g., server racks, aircraft avionics cabinets).
• Specialized Internal Structures:
  • Uniform Air Circulation: Equipped with high-performance fans, air ducts, and baffles to ensure temperature/humidity uniformity (≤±2°C temperature difference, ≤±3% RH humidity difference) across the entire chamber—avoids "hot spots" or "dry zones" that lead to inconsistent sample testing.
  • Adjustable Shelves/Fixtures: Removable stainless steel shelves (for small samples) or custom fixtures (e.g., brackets for solar panels, clamps for wires) to fix samples and prevent movement during testing.
  • Corrosion-Resistant Linings: Internal walls made of 304/316 stainless steel (resistant to rust, moisture, and chemical corrosion) — critical for salt spray humidity tests or pharmaceutical applications (where cleanliness is required).

3. Intelligent Control & Data Management

• Programmable Logic Control (PLC) & Touchscreen Interface:
  • Supports setting multi-segment test programs (e.g., "25°C/50% RH for 2h → 60°C/90% RH for 10h → -20°C/30% RH for 5h, repeated 50x") — no manual intervention is needed once the program starts.
  • Intuitive touchscreen displays real-time parameters (temperature, humidity, remaining time) and alerts (e.g., "humidity deviation," "water tank low") with visual/audible signals.
• Data Logging & Export:
  • Built-in data loggers (with storage capacities of 100,000+ data points) record temperature, humidity, and time at set intervals (e.g., every 1 minute).
  • Data can be exported via USB, Ethernet, or cloud platforms in formats like Excel, PDF, or CSV — easy for report generation and compliance audits (e.g., FDA 21 CFR Part 11 for pharmaceuticals).
• Remote Monitoring & Control (Optional):
  • Some high-end models support Wi-Fi/Bluetooth connectivity, allowing users to monitor test progress, adjust parameters, or receive alerts via mobile apps or PC software — useful for 24/7 unattended testing (e.g., long-term material durability tests).
