Haier Constant Climate Chamber HHS-756

Haier Constant Climate Chamber HHS-756 is a controlled-environment chamber designed for animal and plant tissue culture, drug stability testing (including ICH stability studies), cosmetic stability testing, food shelf-life testing, electronic components aging tests and packaging material stability tests. The unit provides precise temperature and humidity adjustment and real-environment simulation for stable laboratory and industrial testing applications.

Key Features:

• Model: HHS-756; Capacity: 756 L
• Temperature setting range: 5–70 ºC; temperature control precision 0.1 ºC; 27-point temperature uniformity ±0.5 ºC
• Humidity range: 10%–90% RH; humidity fluctuation ±1%; humidity control precision 0.1%
• Power supply: 220–240 V, 50/60 Hz; power consumption approximately 5 kWh per day
• Water consumption: 120–320 ml per day (PTC heating, preheated water and atomized humidification)
• Control and data: 10-inch touch-screen microprocessor PID control; USB/RS485 interfaces; expandable touchscreen memory to 64 GB for long-term data storage
• Sensors: dual PT1000 temperature sensors and high-precision capacitive humidity sensor

Advantages:

• Energy-saving semiconductor design reduces power use to about 5 kWh/day (up to 90% lower than compressor units).
• Low water consumption via PTC preheating and atomized humidification reduces water use to 120–320 ml/day.
• High precision environmental control (±0.1 ºC control resolution, ±0.5 ºC uniformity, ±1% humidity fluctuation) supports reproducible stability and culture testing.
• Rapid internal environment recovery after door opening (temperature recovery to 40 ºC in under 4 minutes; humidity recovery to 75% in under 14 minutes).
• Low-noise, low-vibration operation with multiple alarm and interface options (temperature/humidity/door/sensor/water shortage) and expandable data logging for long-term record keeping.
