Product description

Personnel Grounding Tester for ESD Protected Areas – PGT120 – Wrist Strap & Footwear Testing

Description

The Personnel Grounding Tester PGT120 is a wrist strap and footwear tester designed for access control to ESD protected areas (EPA). It verifies correct grounding connections using audible and visual signals and supports integration with a door opening system via a relay with a dry contact. The unit enables simultaneous wrist strap and footwear testing and can be configured for different test modes, including a hands-free operating mode when used together with a barrier gate.

Key Features

Wrist strap and footwear tester for ESD access control (EPA)
Audible and visual signals to indicate test results
Relay with a dry contact for connection to a door opening system
Adjustable door opening time: 1 s or 3 s
Simultaneous right and left shoe testing via separate measuring circuits
Hands-free footwear measurement possible in combination with a barrier gate (without pressing a contact electrode)
Separate measurement of left and right shoe
Lower limit disabling options for shoe testing and wrist strap testing
Beeper can be configured and disabled
Usable on a bench top or wall-mounted (wall mounting requires an additional wall mounting plate)
Test voltages support IEC 61340-5-1 standard test methods (with changeable test voltage)
