Pocket tachometer Testo 460
Pocket tachometer Testo 460. The pocket tachometer is intended for non-contact measurement of the rotation speed of elements of household and industrial devices. The device reads data remotely and displays information on a large backlit display. The tachometer is equipped with a light emitter, which is directed towards the object being examined. When working with weakly reflective objects, such as machine shafts, reflective stickers are used. Stickers are included with the Testo 460. The “NO” mode is used to accurately determine the rotation speed of turbines, fan impellers and other multi-blade devices. It is enough to specify the number of blades in the settings, and the meter will independently perform calculations taking into account the specified parameters. The mode is activated using the keys on the front panel. In addition to the current readings, the minimum and maximum values can be displayed on the screen. This is necessary for measuring equipment with uneven rotation speed. The HOLD function freezes the data on the screen. The display backlight allows data to be read regardless of lighting conditions. The compact body ensures reliable holding of the device. For easy storage and transportation, the package includes a wrist strap and a belt pouch. A removable protective cover with a metal trim protects the display and tachometer sensor from damage. Features: included in the State Register of Measuring Instruments of the Russian Federation FSIS "ARSHIN"; optical measurement of rpm with LED target indicator of the measurement point; display backlight; convenient data reading even in low light conditions; easy data reading thanks to the Hold function; safety of work in the absence of physical contact with rotating or moving elements; control of inaccessible objects, such as fans behind protective grilles, moving parts behind mesh screens, etc.; high efficiency without preliminary preparation of the equipment under study; ability to work with high-speed devices.
