BENNING ST 725 appliance tester

Mains and battery-operated appliance tester for mobile testing of electrical appliances

• Testing in accordance with VDE 0701-0702, DGUV regulation 3 (BGV A3), BetrSichV, ÖVE/ÖNORM E 8701 and NEN 3140
• Mobile - mains-independent thanks to battery operation
• Simple - operation via push buttons
• Fast - test within a few seconds
• Complete - protective conductor current in differential and equivalent leakage current method
• Testing of devices with mains voltage-dependent switching elements/power supply units/relays, such as electronically controlled devices/tools, information and communication technology devices and devices that can only be fully tested with mains voltage.
• The protective conductor / touch current is measured during mains operation using the required differential / direct method.

Product innovations

• Memory locations for 999 test samples
• 3 direct keys for saving, calling up and printing the measured values
• Mini-USB interface and download software for test report generation in MS Excel®
• Direct print function for test report generation on site via optional BENNING PT 1 printer
• Extended function test and residual current measurement (max. 2 x 5 min.)
• Integrated real-time clock for saving the measured values with test date

Performance features
