Compact, precise multimeter that fits in your pocket and handles common electrical and audio checks. Key benefits Portable size: At 8.8 × 6.0 × 2.5 cm the unit is easy to carry onsite or in a toolkit without sacrificing capability. Multifunction testing: Measures DC/AC voltage up to 1000 V, DC current up to 500 mA, resistance up to 1 kΩ, plus a decibel range from −20 dB to +22 dB for audio and signal work. Analog display for realtime observation: The clear analog meter makes it easy to spot fluctuating readings and transient behavior that can be missed on some digital meters. Saves time and tools: Combines several common measurements into one compact device so you don't need separate instruments for basic electrical troubleshooting and audio level checks. Wide applicability: Suited to industrial, educational, household, and maintenance environments, and useful for engineers, students, and electronics hobbyists. What it does Voltage: AC/DC up to 1000 V for testing outlets, power supplies, transformers, and voltage circuits. Current: DC up to 500 mA for checking small circuit currents and component behavior. Resistance: Up to 1 kΩ for verifying connections, resistors, and basic continuity checks. Decibel: −20 to +22 dB for audio level checks, radio experiments, and signal strength comparisons. Practical use scenarios Maintenance technician: Quickly verify supply voltage and detect unstable lines during routine checks in factories or mining sites. Electronics lab or classroom: Demonstrate circuit behavior, measure small DC currents, and observe changing signals on the analog scale during experiments. Hobbyist radio/audio work: Check audio signal levels and troubleshoot radio receiver stages with the decibel range and resistance checks. A straightforward, pocketsized analog multimeter that provides the essential measurements needed for onsite troubleshooting, classroom labs, and hobby electronics without unnecessary complexity.
