Description
The Coil Master 521 Tab is a professional-grade coil-building workstation built for precision and safety. Designed for experienced rebuilders, this device allows you to measure resistance, fire coils for dry burning, and test voltage output, all in one sturdy platform. With its spring-loaded 510 connector, the 521 Tab supports most atomizers and provides secure mounting during builds. Its bright OLED screen displays real-time resistance or voltage readings with high accuracy. Powered by a single 18650 battery, it includes multiple modes: resistance measuring, voltage output testing, and coil-burning mode. Compact yet powerful, the 521 Tab is the ideal tool for anyone who regularly builds and tests their own coils. Key Features High-precision resistance reader (0.01Ω–9.99Ω) Voltage output testing (0.3V–9.99V) Dry burn mode supports firing coils down to 0.2Ω Spring-loaded 510 connector for secure atomizer mounting Large, easy-to-read OLED screen Powered by 1 × 18650 battery (not included) Reverse polarity and short-circuit protection Safe and stable for advanced coil building Specifications Resistance Range: 0.01Ω – 9.99Ω Voltage Test Range: 0.3V – 9.99V Firing Resistance: ≥ 0.2Ω Battery: 1 × 18650 (not included) Display: OLED digital screen Modes: Meter / Fire / Voltage Check Connector: 510 spring-loaded Dimensions: Approx. 85 × 70 × 50 mm Material: ABS plastic + stainless steel build deck What’s in the Box 1 × Coil Master 521 Tab 1 × Voltage test lead 1 × USB charging cable (for upgrades) 1 × User Manual
