Features:* Essential tool for seasonal inspections: This circulation pump rotation tester is very useful at the beginning of the heating season, allowing users to verify the operation of the circulation pump and identify possible blockages after a long period of inactivity.* for versatile: In addition to testing the circulation pump, the device can also check the operation of the oil burner solenoid valve, making it a for versatile tool for a variety of heating applications.* Clear indication system: The built-in indicator can effectively display the field and rotation direction of most circulation pumps, instantly displaying the pump's performance for quick diagnosis.* Humanized design: The convenient design, the red and white screws rotate synchronously with the pump, allowing users to easily and intuitively confirm the rotation direction of the pump.* Compact and portable: This tester is small and portable and can be hung on a keychain. It is a must-have tool for every plumber or heating contractor to quickly check the operation and rotation direction of the pump.Specifications:*Part Name: Circulation Pump Rotation TesterModel: Red - Electronic Version Light Indicator, Black - Detection*Material: ABS + Magnet*Size: None*Color: shownSimple four-step operation - only for sets with valve openers1. Turn off the power first and remove the motor coil2. Put the tool on the valve stem and make a "click" sound.3. Without a "click" sound, rotate the magnet in the opposite direction4. After completing the manual operation, remove the solenoid valve magnet, rotate the motor coil, repeat the above operation until the valve opens, and then put it back in place.Package Contents:A: 1 * Circulation Pump Rotation Tester (Electronic/ Optional)Notes:1.

• Circulation Pump Rotation Tester: Essential tool for seasonal inspections at the start of the heating season; quickly verifies pump operation and identifies potential blockages after prolonged downtime. Compact with built-in magnet and electronic indicator helps technicians diagnose most circulation pumps efficiently. four-step process ensures reliable when checking motor coil and valve stem function.
• AC Detector Functionality: Built-in electromagnetic field detection allows accurate identification of AC current presence in heating systems. This supports quick diagnosis of oil burner solenoid valves, enhancing troubleshooting efficiency for HVAC professionals. Red and white indicators rotate synchronously with pump direction, providing visual on operational status.
• Oil Burner Solenoid Valve Detection: Designed to test solenoid valve operation in oil-fired heating systems, this tester delivers precise during maintenance checks. The device engages with the valve stem and produces an audible click when properly aligned, indicating correct positioning. If no click occurs, reverse the magnet direction for optimal engagement and repeat until valve opens.
• Human-Centered Operation : Features intuitive red-and-white rotating indicators that mirror the pump's rotation direction for recognition. Lightweight ABS + magnet construction offers long lasting while remaining portable enough to attach to a keychain. for plumbers and heating contractors needing , on-site diagnostics without complex setup or calibration.
• Portable and Use Tool: Small size (11*11*24) makes it to carry and store, suitable for various heating applications including boilers and hydronic systems. Compatible with most standard circulation pumps and solenoid valves. Note: actual color may vary slightly due to lighting and display differences; refer to product images for best representation.
