    FAQ
    • 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.
    • 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.
    • 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.
    • The dry-wet bulb sensor is easy to maintain and resistant to high temperature and humidity, making it suitable for most industrial testing scenarios. The capacitive sensor offers a quicker response and does not require gauze replacement, making it ideal for low humidity environments and high-precision scientific research testing.
    • The chamber is equipped with multiple protection systems including non-fuse switch, compressor overpressure protection, overheating protection, overcurrent protection, fan overload protection, dry burning machine protector, water shortage protection switch, and a fault warning and alarm system to ensure safe and reliable operation.
    • Yes. The chamber supports customization including communication interfaces, chamber volume (from 23L to 1000L), temperature ranges (-20℃ to 150℃, -40℃ to 150℃, or -70℃ to 150℃), and optional water-cooled freezing systems to meet various industrial and research needs.
