IMPORTANT INSPECTION TOOL: The circulating pump rotation tester is crucial for the inspection at the beginning of the heating season, enabling users to confirm the normal operation of the circulating pump and solenoid valve, and quickly detect problems and eliminate faults
MULTIPLE FUNCTIONS: This device can not only test circulating pumps but also evaluate fuel burner solenoid valves, making it versatile in various heating applications
CLEAR DISPLAY: The built in indicator of the circulating pump AC detector can show the field strength and rotation direction. Users can immediately understand the performance of the pump and thus make an accurate diagnosis
EASY TO READ: The ingenious design of the air conditioning detector uses red and white screws that rotate along with the rotation of the pump, allowing users to easily confirm its rotation direction visually
LIGHTWEIGHT AND PORTABLE: This heating circulation pump rotation tester AC detector is compact in size and can be hung on a keychain, which is an important tool for plumbers or heating contractors to quickly assess the operation and waterflow direction of water pumps
