PS-A2 Human Body Electrostatic Discharge Alarm

It was designed with a comprehensive feature set, including human presence detection, voice notification, real-time voltage display, and interlocking signal output for integration with external control systems. These features helped enhance workplace safety by minimizing the risks caused by uncontrolled static discharge on operators.

Although the PS-A2 model is no longer in production, having been succeeded by the more advanced PS-A3, APT still provides replacement accessories and customization services for existing systems. This ensures long-term operational continuity for clients who still rely on PS-A2 units in their facilities.
