    FAQ
    • 1. Why use pure water or distilled water?
      The impurities present in tap water can easily form scale, causing blockages in the humidification pipeline and reducing the accuracy of the humidity sensor's detection.
    • 2. How often should the humidity sensor wick be replaced?
      Based on the water quality and usage frequency, it is recommended to replace it every 3 months. This device comes with a box of replacement parts as a standard.
    • 3. Can the equipment undergo a stability test lasting for 30 days or even longer?
      Yes. The equipment is equipped with automatic water replenishment function in case of water shortage and multiple protection functions against overheating. It can support long-term continuous operation without human intervention.
    • 4. What is the difference between air-cooled and water-cooled freezing systems?
      The air-cooled system is the standard configuration, suitable for general laboratory environments with good ventilation. The water-cooled option is ideal for confined spaces or environments with high ambient temperatures, offering more stable cooling performance.
    • 5. Does the chamber support remote monitoring or data logging?
      Yes. The chamber features a built-in communication interface (RS232/RS485 or optional Ethernet) that supports data logging, remote monitoring, and integration with laboratory management systems. The LCD touch screen also allows on-screen program setup and historical data review.
    • 6. What safety protections are built into the chamber?
      The chamber includes multiple protection mechanisms: non-fuse switch, compressor overpressure protection, overheating and overcurrent protection, fan overload protection, dry-burn prevention, water shortage protection switch, and a fault warning alarm system — ensuring safe and reliable long-term operation.
