Searching for a high-performance tool to test coil turns and (for R-model) DC resistance? The CH1201 Series—CH1201 and CH1201R—combines precision, efficiency, and ease of use, making it perfect for coil manufacturing, maintenance, and quality control in industries like motor, transformer, and relay production.
1. Shared Core Features (Both Models)
-
High-Accuracy Coil Turns Testing: Specialized for motors, transformers, generators, and relay coils; no manual calibration or range switching required, ensuring quick startup.
-
Broad Coil Compatibility: Tests coils with inner diameter >4mm, outer diameter <120mm, and height <110mm; use Φ9.5 sensor when the inner diameter of the tested coil exceeds 30mm for optimal accuracy.
-
Efficient Operation: Automatic range selection and 6-bit LED display for clear, real-time readings; fast measurement speed (3 times/second) adapts to rapid testing needs.
-
Practical Functionalities: Supports "Open/Phase/Mute" signal settings, enabling customization for various testing scenarios.
-
Durable & Stable Design: Operates in 0℃~40℃ (≤90%RH); compact dimensions (335mm×320mm×290mm) and ~6Kg weight for easy placement; power supply 198-242VAC 47.5-52.5Hz (power consumption ≤30VA).
