ESI 195 Super Relay Buddy® Pro Kit – 12V Relay Tester + Adapter Set

7+ Amp Load | Green/Yellow/Red LED Results | Tests 10 Relay Types

The ESI 195 Super Relay Buddy® Pro Kit expands on the capabilities of the standard ESI 194 by including adapters to test 10 types of 12V relays. Like the base model, it applies a 7+ amp load to simulate real-world relay conditions and catch those that fail under load. A tri-color LED system provides quick diagnostic feedback: Green (Good), Yellow (Caution), or Red (Fail).

The Pro Kit is ideal for technicians working across a broad range of applications including automotive, heavy-duty, marine, RV, and equipment diagnostics.
