Stroboscopic tachometer Testo 477 (LED)
Stroboscopic tachometer Testo 477 (LED). The LED portable strobe measures rotation speed and vibration intensity and allows measurements to be taken while the units are running. The permanent installation option allows inspection and quality assessment of high-speed components. The device allows you to perform quick measurements on objects and areas of very small sizes, direct access to which is impossible without interrupting the production process. Such measurements are possible due to the absence of the need to use reflective markers. A powerful LED strobe light allows you to create a visual effect of slow motion of fast-moving objects and detect rotation speeds up to 300,000 rpm. The tachometer housing is equipped with a connector for connecting external devices. In addition, the body of the device has a connector for installing a tripod, so the device can be used as a stationary one, which will be useful when measuring fast-moving parts. The case is perfectly protected from moisture and complies with protection class IP65. The tachometer has a multi-line, user-friendly screen that contains all the main indicators. Power can be supplied either from a set of 3 AA batteries or from 3 rechargeable nickel batteries. The battery life in the first case is 5 hours, in the second - 11. Features: included in the State Register of Measuring Instruments of the Russian Federation FSIS "ARSHIN"; extremely wide measurement range: up to 300,000 flashes per minute; very high level of light intensity: up to 1500 lux; trigger connector provides the ability to connect to external systems and control via an external sensor; Suitable for use in harsh environments thanks to its environmental protection and IP65 rating.
