Electronic Moisture-proof Cabinet Quality Evaluation and Maintenance Guide
1. Core indicators for quality assessment
Dew point removal performance
The preferred option is to use molecular sieves or semiconductor condensation technology models. The dehumidification speed should be ≤ 2 hours (industrial grade).
The humidity control accuracy should reach ±5%RH. Ultra-low humidity models should support below 10%RH.
Anti-static design
Check the surface resistance value of the cabinet (10^4 - 10^11 Ω/square)， to avoid damage to electrostatic-sensitive components.
Sealing verification
Observe whether the sealing strips at the door gap are flat and without deformation. After closing， there should be no light leakage phenomenon.
II. Key Points of Daily Maintenance
Regular Inspection
Clean the filter screen of the mechanism monthly to prevent dust from blocking and affecting the dehumidification efficiency.
Calibrate the built-in sensor using a third-party hygrometer. If the error exceeds ±3%, contact the after-sales service.
Fault Handling
If the humidity does not decrease: Check if the mechanism valve is stuck or if the molecular sieve is aged (replacement required).
Display abnormalities: Reset the instrument or contact the manufacturer for calibration.
III. Purchase Suggestions
Industrial users: Choose high-strength moisture-proof cabinets (humidity range 1%-50% RH), which are better at removing moisture with nitrogen gas.
Home users: The electronic mechanism type (such as silica gel desiccant) offers better cost-effectiveness. Remember to regenerate it regularly.
