ST100 Pro Professional Spark Plug Tester




Advantage

ST100 Pro simulates auto engine system ignition process(0-6000RPM frequency available),test the spark plug performace


Application

This product is designed for automotive spark plug testing, featuring easy operation and efficient performance.


Technical parameter

Must Have! Engine hard to start, poor acceleration, or abnormal fuel consumption? Your spark plugs may be faulty—test them with this spark tester! It quickly assesses performance, determines replacement needs, and outperforms traditional inline testers.

Why Dual-Hole? Test and compare two spark plugs simultaneously for ignition intensity and performance. Accurately judge condition, replace faulty ones promptly, and save time/money by avoiding unnecessary replacements.

Simulate Engine Ignition: Adjust frequency (0-6000 RPM) to replicate real engine ignition—higher frequency = stronger spark. Ensures efficient, precise testing.

Plug & Play: Insert plugs, attach the observation plate, connect power, and adjust frequency. Indicator lights and high-voltage signals let you check spark performance at a glance.

Upgraded Version: Enhanced high-voltage coil pack and chip deliver stable power. Heat/impact-resistant for long service life. Black plate ensures clear spark visibility (better in dim environments).

Fits Most Plugs: 13mm socket works with plugs (insulator diameter ≤13mm). Use included shims for smaller/longer plugs.

Wide Application: Essential for 12V gasoline engines (cars, motorcycles, crankshaft engines). Ideal for individuals, mechanics, and auto shops.

NOTE: Not for short plugs in lawn mowers/chainsaws/small motors. Spark plugs not included.
