Low humidity cabinets can store sensitive items in a moisture controlled environment, typically by maintaining a relative humidity (RH) level well below the ambient air. These dry cabinets are ideal for preserving electronics, documents, photographs, and other items susceptible to moisture damage.
How does humidity cause microcracks?
Humidity can cause microcracking in materials, especially those prone to moisture absorption, such as certain ceramics, composites, or electronics. Here’s how:
Humidity often accompanies temperature fluctuations. Materials expand or contract due to combined thermal and moisture effects.
Materials, like polymers and composites, absorb moisture from humid environments. This absorption leads to swelling, causing internal stresses. When the material’s structure cannot accommodate this swelling uniformly, localized stress points develop, leading to microcracks.

An electric drying cabinet, also known as a Dry box or Dry cabinet, is an air-tight dehumidifying dry storage cabinet, which can maintain 1-10%RH humidity levels. Low-humidity cabinets can protect components from moisture and humidity-related damage, such as rust, mold, and oxidation.
A dry box for electronics is used to protect and store Surface Mount Technology (SMT) Parts, Moisture Sensitive Devices (MSD), 3D Printing polymers, Semi-finished items, Automotive Parts, Printed Circuit Boards (PCB), Integrated Circuits, Metal Powders, Solder Paste and other manufacturing related materials.
This chart shows, in the ambient 25 degree C, humidity 50%RH, open door 30 seconds and then close, the humidity can recover to the set point within 30 minutes.
Relative Humidity | Suggested storage items |
55%~45%RH | Tapes, CD, lenses, microscope,photograph, oil paintings, stamps, coins, antiques, leather goods, negative, drawings, album, slides, industrial design, etc |
45%~35%RH | Optical lenses, precision instruments, camera, lenses, measuring tools,capacitors, batteries, EI, light sources, crystal, PCB, detector, charger, microscopes, endoscopes, electronic appliance, magnetic tape, chemical, tea, coffee, seeds, cigarette, etc. |
35%~20%RH | Samples,filters, precision dies,measurement instruments, pollen, all electronic components, PCB, wafer, metallic powders, semiconductors, medical supplies etc. |
10%~20%RH | Electronic components, PCB, crystal, chemical, LED and other complicated electronic components, etc. |
10%-1%RH | IC, BGA, copper, silver, and materials very sensitive to humidity,etc |
5%-1%RH | Open IC packages, PCB packages, microelectronics, MSDS, etc. |
Two years, if any defects after receipt, we will solve it asap, including spare parts sending, online installation guidance, if the defects can’t be settled, we will recall the cabinets, and send a new unit for free. However, , this case has never happened, no worry.
Relative humidity is a very sensitive coefficient and is easily affected by the external environment. Therefore, the recovery time depends on many factors, such as the door opening time, surrounding environment, and storage items. Under normal circumstances, when the ambient temperature is 25 deg C and the humidity is < 60%RH, if the door opening time is within 15 seconds, the humidity can reach below 5%RH within 15-30 minutes.
Some electronic components, such as PCB, BGA, IC, chips, etc., require low humidity storage environment. Desiccant storage cabinets can control humidity and protect them from moisture immersion, making drying cabinets the optimal choice for storing electronic components. Electronic devices in the process of operation, semi-finished products in packaging for the next process, unused ICs, BGAs, PCBs after unpacking, devices waiting in the oven, devices waiting for temperature to be returned after baking, and unpackaged finished products can be damaged by moisture.
The humidity sensor accuracy is +/-2%RH, the long-term drift is <0.25%RH/yr, and we have calibrated every unit before ex-factory. We suggest that no need calibration is required for the first 2 years, if it is indeed required, we recommend using the ROTRONIC, Swiss-made hygrometer HP21, HP22 or HP23.
