The Shimpo DT-900-UP battery-operated digital stroboscope has a xenon light source, internal and external trigger modes, and phase shift and time delay features. It provides stop-action or slow-motion viewing of moving machinery for visual inspection of covered gear teeth, shafts, print media, and various injector patterns. The xenon flash tube has a 9 to 15 microsecond flash duration to provide crisp images in brightly lit areas. Xenon flash tubes have brighter light output and a shorter flash duration than LED lights. Bright light output is required for quality images in brightly lit areas, and shorter flash durations provide sharper images, especially at high rates of speed. The stroboscope has a range of 40.0 to 12,000 flashes per minute (FPM) and an accuracy of + or - 0.5% FPM, or + or - 0.01% of reading, whichever is greater. The tachometer mode has a speed measurement range of 40 to 59,000 rpm and an accuracy of + or - 0.5% FPM, or + or - 0.01% of reading, whichever is greater. Built-in multiply-by-2 and divide-by-2 functionality allows the operator to distinguish true RPM from harmonics. Phase shift enables the operator to adjust the focal point of the object to any point in the rotation without moving the trigger point. The 8-digit 2-line LCD display eases reading in low lighting. An integrated 1/4" - 20 Unified Coarse (UNC) mounting thread allows the stroboscope to be mounted on a tripod for long-term use. The rechargeable NiMH battery has a life span of 1.24 to 2.5 hours, depending on flash rate and can be removed for recharging using the 120V AC adapter (included). The housing is comprised of impact and oil-resistant polycarbonate for durability. The stroboscope includes two NiMH rechargeable batteries, a universal 120/240V AC charging adapter, a padded belt holster, a replacement flash tube, a protective carrying case, and instructions. Stroboscopes are used in a variety of settings including manufacturing, printing, education, and photography.

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.
