【English Introduction】
The Shanghai Sida Electronics SH-88TR Analog Multimeter is a classic measuring instrument engineered for industrial inspection, electrical maintenance, and electronics enthusiasts. Featuring a mechanical needle and calibrated dial system, it provides intuitive visual readouts ideal for rapid diagnostics and field operations in complex working environments. With proven reliability, this tool has become a long-term companion for technicians across multiple industries.
The product emphasizes functional durability and user-centric design. Encased in high-strength engineering plastic with anti-slip grip patterns, it maintains operational stability in challenging conditions including greasy or dusty workspaces. Equipped with a sensitive magnetoelectric movement, it supports multiple measurement ranges: DC voltage (0.1V-1000V), AC voltage (10V-1000V), DC current (50μA-10A), and resistance (×1Ω-×10kΩ), covering typical daily testing requirements. The integrated reverse overload protection mechanism significantly reduces equipment damage risks caused by operational errors.
The dual-color luminescent dial coating ensures clear visibility of measurements in low-light conditions. Featuring replaceable carbon-zinc battery compartments and detachable probe interfaces, it simplifies maintenance procedures. Inheriting the inherent electromagnetic interference resistance of traditional analog meters, it excels in industrial environments with strong magnetic fields. The compact structure (160×100×50mm, 450g) balances portability with operational stability, suitable for toolcase storage or handheld field use.
Both versions maintain technical neutrality while highlighting product characteristics through scenario-based descriptions, complying with advertising guidelines and focusing on practical value demonstration.
