Questions about this product
- What does this spark plug tester actually check?
- It checks whether a spark plug fires correctly and shows the spark rate as RPM from 0 to 6000. You use it to spot weak or dead plugs that cause misfires. The two holes let you compare two plugs side by side.
- Will it run on my workshop's power?
- Yes, it accepts both 110V and 220V, so it works in most regions without a converter. That makes it handy for shops that switch between supply voltages. Just plug it into a standard outlet for your area.
- Is this meant for pro shops or home mechanics?
- Both. Repair shops use it for quick checks during maintenance, and DIY mechanics use it to test plugs before installing them. The dual-hole layout speeds up sorting good plugs from bad ones.
