Need a reliable tool to test coil turns and (for R-model) DC resistance? The CH1200 Series—including CH1200 and CH1200R—delivers high accuracy, fast speed, and easy operation, ideal for manufacturing, maintenance, and quality control of winding coils.
1. Shared Core Features (Both Models)
High-Precision Coil Turns Testing: Designed for motors, transformers, generators, and relay coils; no manual calibration or range switching needed.
Wide Coil Compatibility: Tests coils with inner diameter >4mm, outer diameter <120mm, and height <110mm (use Φ9.5 sensor for coils with inner diameter >30mm to ensure accuracy).
Efficient Measurement: Automatic range selection and 6-bit LED display for clear, real-time readings.
Practical Functions: Optional "Open/Phase/Mute" signal settings to adapt to different testing scenarios.
Durable & Stable Build: Operates in 0℃~40℃ (≤90%RH); dimensions 335mm×320mm×290mm, weight ~6Kg; power requirement 198-242VAC 47.5-52.5Hz (power consumption ≤30VA).

Ideal Use Scenarios
Basic coil turns testing (e.g., small motor coils, relay coils) where resistance measurement is not required. Suitable for entry-level quality checks in small workshops or repair shops.
Comprehensive coil testing (e.g., transformer windings, generator coils) that requires both turns verification and DC resistance measurement. Ideal for professional manufacturing lines or labs with strict quality control.
