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 ±3% RH accuracy of the Honeywell sensor affect long-term reliability for mid-humidity storage?

The Honeywell sensor provides ±3% RH accuracy with only 0.3% annual drift. This ensures consistent measurement over years without recalibration. For mid-humidity (20%-60% RH), this accuracy is sufficient to prevent moisture-related damage like oxidation or solderability loss without requiring ultra-dry conditions.

Can this dry cabinet be integrated into an existing laboratory monitoring system for real-time humidity tracking?

Yes. The optional RS485 PC logging interface enables real-time data logging and remote monitoring of cabinet humidity and temperature status. This allows integration with laboratory management systems for traceability. Additionally an over-humidity alarm option can trigger alerts when internal humidity exceeds set points.

What are the critical installation requirements for maintaining stable humidity control in this dry cabinet?

The cabinet must be transported upright with reinforced outer protection. After installation confirm level placement door sealing shelf loading and stable power before storing sensitive materials. Keep the cabinet door closed during normal use to minimize ambient exposure which could compromise humidity stability.
