III. Parameters Distinguishing the Two Models
YG108R Series (with resistance measurement function)
Total unit weight: approximately 10 kg;
Resistance measurement range: 0.00001 Ω to 100 kΩ;
Resistance measurement accuracy: ±0.2%, valid measurement range 0.1Ω–100KΩ.
YG108 Basic Series (turns counting only, no resistance measurement)
Unit weight: approximately 8 kg; does not feature coil resistance measurement.
IV. Product Description
Both models share identical specifications regarding coil size compatibility, turns counting accuracy, speed measurement ranges, and unit dimensions; The number at the end of the model number corresponds to the minimum compatible coil inner diameter and the matching sensor probe size.
For applications requiring only turn counting and prioritizing portability, choose the YG108 Basic model; for applications requiring both turn counting and DC resistance measurement—such as quality inspection of transformer and motor coils—select the YG108R series.
