When you arrive at a new campground and plug into shore power, you need to know the connection is safe. This handheld tester checks for three critical faults—open ground, open neutral, and reversed polarity—that can damage your appliances or create fire hazards. The LCD display makes results obvious at a glance, and the one-hand design lets you test with your gear already in place.

• LCD display shows test results clearly
• No leads or batteries required
• Simple one-hand operation
