Haier Constant Climate Chamber HHS-256

Haier Constant Climate Chamber HHS-256 is a controlled environmental chamber that provides accurate temperature and humidity adjustment and control for stability studies and environmental testing. It is designed for drug and cosmetic stability tests, food shelf-life tests, electronic component aging tests and packaging material stability tests, and is equipped with real environment simulation functions and a 10‑inch touch screen for data display and control.

Key Features:

• Model: HHS-256; Capacity: 256 L
• Power supply: 220–240 V ~ 50/60 Hz
• Temperature setting range: 5–70 °C with temperature control precision 0.1 °C
• Humidity range: 10–90% with humidity control precision 0.1% and high-precision capacitive humidity sensor
• Standard/maximum shelves: 2 / 5
• Interfaces: USB and RS485 standard; touchscreen memory expandable to 64 GB
• Sensors: Dual PT1000 high-precision temperature sensors

Advantages:

• Energy-saving semiconductor control with power consumption about 5 kWh per day, reducing operational costs
• Low water consumption (120–320 ml/day) via intelligent PTC heating and atomized humidifying, eliminating need for wastewater reclamation
• Fast environment recovery (temperature and humidity return quickly after door opening) for stable test conditions
• Low-noise, low-vibration operation due to semiconductor control for clean laboratory environments
• High-precision control and data storage (expandable to 64 GB) for reliable, long-term stability testing and audit-ready records
