Analog Multimeter with Continuity Check Beeper

SP21 Analog Multimeter: Precision, Durability, and Instant Continuity Feedback

Looking for a reliable and robust analog multimeter for your low-voltage electrical work? The SP21 Analog Multimeter with Continuity Check Beeper delivers exceptional performance, packed into a durable, user-friendly design. It's the ideal tool for electronics enthusiasts, hobbyists, and technicians working with sensitive circuits.

Unmatched Precision and Versatility: The SP21 features a high-quality taut-band type meter, known for its superior accuracy and improved sensitivity compared to traditional pivot-and-jewel movements. This ensures you get precise readings every time. With a 3% full-scale accuracy, you can trust its measurements across a wide range of functions:

• DCV (Direct Current Voltage): Measure 0.3V up to 600V with a unique zero-center for ±DCV measurements, allowing for easy identification of positive and negative polarity without lead swapping.
• ACV (Alternating Current Voltage): Accurately measure 12V up to 600V, with a frequency response up to 100kHz on the 12V range.
• DCA (Direct Current Amperage): Test current flow from 60µA up to 0.3A.
• Resistance: Check resistance across three ranges: 2kΩ, 20kΩ, and 2MΩ.
• Capacitance: Get approximate values for capacitances up to 500μF.

Instant Continuity with Audible Beeper: Speed up your troubleshooting with the built-in continuity test function. An audible buzzer alarm sounds instantly when resistance is less than approximately 10Ω (or up to 100Ω depending on the model), making it incredibly easy to identify shorts, open circuits, and verify connections without having to constantly look at the meter. This is invaluable for wiring checks and component testing.

Built for Durability and Safety: The SP21 is engineered to withstand the rigors of everyday use. Its shock-resistant design is complemented by a robust protective case with a built-in kickstand, allowing for convenient hands-free operation and enhanced durability against accidental drops. The case is constructed from fire-retardant material, adding an extra layer of safety. Furthermore, its internal circuitry is safeguarded by a (250V/0.5A) fuse with a 300A blowout capacity, providing critical protection against overloads and ensuring the longevity of your device.

Key Features at a Glance:

• Drop shock proof taut-band meter for enhanced accuracy and resilience
• ±DCV zero center meter for intuitive positive/negative voltage readings
• Fuse and diode protection for superior safety
• Battery check function for 1.5V and 1.5V button batteries
• Integrated tilt stand for comfortable viewing

Important Note: The SP21 multimeter is specifically designed for low-voltage circuit analysis and must not be used to measure high power voltage lines (e.g., mains electricity). Please adhere to all safety guidelines.
