Key Features and Advantages

Selectable humidity grades are split into individual models: A mid-humidity 20%-60% RH, B low-humidity 10%-20% RH, C ultra-low-humidity 1%-10% RH and D extreme-low-humidity 1%-3% RH, allowing the cabinet to match the actual sensitivity of stored materials.
High-precision sensing uses a Honeywell temperature and humidity sensor with ±3% RH accuracy and low annual drift for reliable long-term measurement.
Efficient automatic dehumidification removes moisture rapidly, requires no disposable desiccant consumables and supports continuous operation with minimal maintenance.
Intelligent microcomputer control retains set parameters after power loss and shows real-time humidity, temperature, operating status and fault codes on the LCD display.
Robust sealed construction uses a galvanized steel cabinet body, tempered safety glass, double-frame sealing, magnetic gaskets and a lockable handle for stable dry storage.
Perforated adjustable shelves support uniform air circulation and make it easier to store components, instruments and samples of different sizes.

FAQ

How does the Honeywell sensor's ±3% RH accuracy and 0.3% annual drift affect long-term stability of the 10–20% RH set point in the Atomfair DC450B dry cabinet?

The Honeywell temperature and humidity sensor provides ±3% RH accuracy with only 0.3% annual drift, ensuring reliable long-term measurement for the 10–20% RH low-humidity range. The microcomputer control retains set-point memory after power interruption, so the cabinet maintains consistent humidity control without recalibration drift over time.

Can the Atomfair DC450B low-humidity cabinet be integrated into an ESD-controlled production line without additional modifications?

The standard cabinet has a white powder-coated steel body, which does not provide electrostatic protection. For ESD-controlled areas, an optional ESD-safe anti-static coating compliant with IEC 61340-5 handling requirements is available and must be specified at order time to ensure compatibility with ESD-sensitive component storage.

What specific handling and installation procedures are required for the 450L dry cabinet to ensure proper sealing and humidity control?

The cabinet must be transported upright with reinforced outer protection and moved with suitable lifting equipment due to its volume. After installation, confirm level placement, door sealing via the magnetic gasket and lockable handle, shelf loading limits, and stable power before storing sensitive materials to maintain the sealed low-humidity environment.
