Portable Speed Tester for Real-Time Speed Measurement

Elevator Speed Measuring Instrument is a handheld device designed for elevator commissioning, maintenance, and inspection. It is compact, lightweight, and battery-powered, allowing flexible use in space-constrained environments such as elevator machine rooms and shaft tops. Elevator Speed Measuring Instrument is equipped with two display channels and corresponding test modules, enabling synchronous multi-parameter measurement on site.   In routine maintenance work, periodic overspeed governor action speed tests are required to ensure that the governor can reliably trigger the safety gear when the elevator overspeeds. The use of Elevator Speed Measuring Instrument makes the operation process simple and efficient. Before testing, the two test modules are connected to the governor sheave and corresponding measurement points respectively. Once the instrument is powered on, the speed values of the two channels are displayed in real time. During the action speed test, the elevator is starte…
