Progressive Industries
Progressive Industries Smart Surge Protectors (SSP) are portable RV surge protectors with the added benefit of a built-in polarity tester. The built-in surge indicator notes the condition of the surge protector. Additionally, the polarity tester (dual line for 50A) checks the status of the power source prior to use. Sleek, compact, portable design makes it easy to use and store. Designed for outdoor use. No installation required.

8471D -
Keysight Technologies
The Keysight 8471D is a low-cost, planar-doped barrier detector offering excellent performance to 2 GHz. A negative polarity output is standard, and a positive polarity is available as Option 103. A load option (Option 102) extends the square-law region to at least -10 dBm. The Keysight 8471D has a BNC (m) input connector and a frequency range of 100 kHz to 2 GHz, making it ideal for use in RF and low microwave applications.
