1109 Analog Multimeter Introduction
Product Overview
The 1109 analog multimeter is a classic needle-type measuring instrument developed in the 1990s. Featuring a shock-resistant ABS housing and dual battery compartments (1.5V/9V), this portable device remains popular for basic circuit diagnostics in electronics maintenance, educational labs, and industrial applications.
Key Features
• Multiple Ranges: Measures DC Voltage (0-1000V), AC Voltage (0-500V), Resistance (×1Ω to ×10kΩ), and Current (0-500mA)
• Visual Operation: 7-inch curved scale with dual-color markings enables ±2.5° viewing angle
• Safety Components: Ceramic fuse protection and silicone-sealed terminal blocks
• Ergonomic Design: Anti-slip zero-adjust knob and gold-plated test lead jacks
Applications
Ideal for entry-level electronics repair (home appliances, audio systems), vocational school workshops, and basic industrial control panel testing. The analog display effectively demonstrates real-time parameter fluctuations in circuit analysis.
Manufacturing
Produced by Huayi Tools, a Guangdong-based manufacturer specializing in analog instruments since 1987. Core components include Japanese-made hairsprings and German precision bearings, with each unit undergoing 72-hour continuous calibration testing.
Pricing
Retail price ranges from 12to18 USD depending on configuration. Bulk orders receive quantity-based discounts. Optional accessories include replacement test leads, spare fuses, and canvas carrying cases.
