Trek® 156A Charge Plate Monitor

The Trek® 156A tests the efficiency of an ionizer’s ion production by timing how long it takes air ions produced to discharge a floating plate that has been pre-charged to either a positive or negative value. The Trek 156A also tests the balance between positive and negative air ions by measuring the offset voltage generated on a floating plate due to an imbalance of positive and negative air ions impinging on the plate from the ionizer.

PRODUCT HIGHLIGHTS

• Customizable measurement capacitance provides assurance that ESD process needs are met in manufacturing and that there is compliance to ANSI/ESD-STM3.1 and IEC 61340-5-1
• Extremely low offset and drift ensures high accuracy, making it ideal for applications requiring critical ion balance such as GMR and TMR manufacturing areas
• Compact and lightweight, for easy portability within a facility
• NIST-traceable Certificate of Calibration provided with each unit

APPLICATIONS

• ESD monitoring of sensitive manufacturing processes such as semiconductor, disk drive and LCD
• Testing of all types of ionizers, including room ionization systems, AC and DC blowers, nuclear ionizers, gun type ionizers, and pulsed DC ionizers
• High temperature applications
