Testo 476 Handheld Stroboscope, 30 to 12500 rpm Range, 1 rpm Resolution

The Testo 476 pocket stroboscope has a xenon flash tube, a 30 to 12,500 flashes per minute (FPM) range, and an integrated tripod mount, and is used for motion analysis, preventive maintenance, printing inspection, and speed measurement of repetitive motion in small or confined spaces. The xenon flash tube has flash duration of less than 20 microseconds and a light output of 800 lux at a distance of 20cm to provide crisp images in brightly lit areas. The 5-digit LED readout has a 1 FPM resolution. The memory function recalls the last reading before powering off. The stroboscope can be powered by an internal rechargeable battery pack or by using the universal 110/240V AC power supply. The stroboscope battery will recharge while in use with the AC power supply. The stroboscope includes a universal 110/240V AC power cable/battery charger, a trigger signal connector, carrying case, and instructions. Stroboscopes are used in a variety of settings including manufacturing, printing, education, and photography.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Stroboscopes evaluate the functionality of fast-moving rotational objects, such as belts, fan blades, and other machine parts. They are used in industries such as manufacturing, entertainment, high-speed printing, wood and metal turning, and in education and research settings. Stroboscopes have a flashing light (strobe) that, when directed at a moving object, makes the object appear to be stopped or moving in slow motion. This enables the operator to evaluate machine performance without stopping the machine. Stroboscopes use either xenon flash tubes or LED light sources. The strobe is triggered either internally, which allows the operator to manually adjust the flash rate, or externally and automatically by a peripheral sensor. Multiply-by-2 (2/4 or 2X) and divide-by-2 (1/2) functionality enables the operator to verify the actual revolutions per minute (RPM) and to distinguish true RPM from harmonics. Phase shift adjusts the flash delay in degrees of a full rotation, and time delay adjusts the flash delay in seconds or fractions of a second. Input and output features enable the operator to use peripheral sensors to trigger flash rates, to perform tachometer operations, or to daisy-chain stroboscopes.

Testo manufactures portable test and measurement instruments. The company, founded in 1957 in Germany, has a U.S. office in Sparta, NJ, and meets International Organization for Standardization (ISO) standard 9001.
