Question 1

What humidity level helps reduce static electricity (ESD)?

Accepted Answer

For many electronics/PCB environments, 50–60% RH is commonly used to reduce static electricity risk (ESD).

Question 2

What is a dry fog ultrasonic humidifier?

Accepted Answer

A dry fog ultrasonic humidifier uses high-frequency piezoelectric atomization (e.g., 1.7MHz) to generate very fine droplets (typically ≤5 μm) for fast humidity control with reduced wetting risk.

Question 3

What is the difference between ultrasonic fogging and high-pressure misting?

Accepted Answer

Ultrasonic fogging produces fine droplets via piezoelectric vibration, while high-pressure misting uses pumps and nozzles. Droplet size, wetting risk, maintenance, and energy use can differ by application.
