Ignition Coil Tester
Upgrading Workshop Diagnostics: Why Importers Choose QBH
Solving the core frustrations mechanics face with traditional spark plug testers.
Hard-to-Reach Coils
Modern engines are compact. Our WT05 features a 35±10mm flexible probe that easily accesses deep or obscured ignition coils.
Fragile Workshop Tools
Diagnostic tools drop often. We wrap the WT05 in a heavy-duty, wear-resistant, and anti-skid rubber sheath built for real garages.
Vague Visual Testing
Stop guessing with visual spark gaps. Our high-sensitivity capacitive sensor displays precise Spark KVolt (0-50 KV) and Burn Time (0-10 ms) on an LCD screen.
Incompatible Systems
The WT05 seamlessly switches between COP (Coil-on-Plug) and SPW (Spark Plug Wire) measurements for 2-cycle, 4-cycle, and DIS engines.
