TOS9300 series is a multi-analyzer for safety testing of electronic devices and components.
It provides the following test functions:
• Withstanding voltage test
• Insulation resistance test
• Earth continuity test
• Leakage current test (touch current, protective conductor current, patient
leakage current)
• Partial discharge test
You can select the model based on your test requirements, allowing you to
perform multiple safety tests with a single tester.
The series is suitable for R&D facilities, quality assurance testing, standards certification organizations, and production lines.

Key features include:

• All-in-one model (TOS9303LC)
• Up to 40A AC/DC earth continuity testing (TOS9302/9303/9303LC)
• Adjustable insulation breakdown detection sensitivity
• Withstanding voltage test function: AC 5 kV/100 mA, DC 7.2 kV/100 W
• Withstanding voltage test function: AC 10 kV/50 mA, DC 10 kV/100 W (TOS9311)
• Leakage current testing capabilities (touch current, protective conductor current, patient leakage current) capabilities (TOS9303LC)
• Partial discharge testing (TOS9301PD)
• Standard LAN, USB, and RS232C communication interfaces
• High visibility color LCD display
