KF-8 Analog Multimeter Product Introduction (English Version)
The KF-8 analog multimeter is a classic-style portable measuring instrument featuring a traditional mechanical pointer display system, ideal for basic circuit testing, educational demonstrations, and routine equipment maintenance. Maintaining the intuitive operation advantages of analog instruments, the device incorporates a high-contrast dual-color scale dial with anti-vibration damping mechanism, effectively reducing needle oscillation during dynamic measurements for clear and stable readings.
Equipped with a sensitive magnetoelectric meter movement (20kΩ/V sensitivity), the device integrates multi-layer protective circuitry capable of measuring AC/DC voltage (0-1000V), current (0-500mA), and resistance (0-2MΩ). The mirrored scale calibration strip and adjustable zero-position knob enable precise alignment observation. The mechanical zero-adjustment mechanism utilizes stainless steel bearings, laboratory-verified to withstand over 100,000 rotational adjustments for extended durability.
Constructed with engineering-grade ABS housing and anti-slip rubber edging, the 380g lightweight design incorporates an ergonomic tilt stand for desktop operation. Dual overload protection activates through ceramic fuse interruption when exceeding measurement ranges, complemented by silicon steel magnetic shielding technology for enhanced safety. The package includes dual-purpose test leads with alligator clips and sharp-tip probes for versatile connectivity.
Particularly valuable in electronics education, the mechanical pointer s dynamic response helps learners visualize circuit parameter variations. The instant needle response proves advantageous for industrial field diagnostics and household appliance maintenance requiring quick continuity checks or voltage status judgments. Regular calibration using the included potentiometer is recommended, with horizontal storage advised to protect the movement mechanism.
This instrument combines reliable measurement capabilities with operational simplicity, offering a cost-effective solution for fundamental electrical parameter detection. Its durable construction and straightforward maintenance make it a practical choice for entry-level technicians, hobbyists, and educational institutions seeking dependable analog measurement tools.
