Monarch Nova-Strobe dbx 115/230 Deluxe Battery-Powered Digital Portable Stroboscope, with NIST Certificate of Calibration, 3.56" H x 9" L x 3.66" W
The Monarch 6204-012 Nova-Strobe dbx battery-powered digital stroboscope with xenon flash tube, internal and external trigger mode, and internal phase shift displays rate in FPM (flashes per minute) or flashes per second (Hz). It is designed for motion analysis, preventive maintenance, printing inspection, harmonics analysis, and speed measurement of repetitive motion. Internal and external trigger modes have a flash rate range of 30 to 20,000 FPM. Internal flash rates can be adjusted in 0.1 step increments using the coarse/fine adjustment knob. A digital microprocessor keeps readings accurate. Built-in multiply-by-2 and divide-by-2 push buttons allow the operator to distinguish actual rpm from harmonic frequencies, and provides stop-motion viewing beyond the 20,000 FPM limit. Tachometer mode measures speed up to 250,000 rpm with external sensor (not included). Separate transistor-transistor logic (TTL) input and output jacks (1/8" phone) provide power to remote sensors and allow multiple strobes to be daisy-chained to provide wider coverage. The xenon flash tube has a 20 to 50 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. Continuous duty cycle and built-in threaded mount allow the stroboscope to be mounted for long-term use without cool-down periods. Data storage and recall for up to six user-selectable values and last measurement memory are retained even after power-off. The stroboscope is powered by 6V DC internal rechargeable batteries with an operating time of approximately 60 minutes at 6000 FPM. It includes a NIST Certificate of Calibration and a universal charger with USA, U.K., AUS, and EURO wall plugs. 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.
Monarch Instrument manufactures devices such as tachometers, stroboscopes, data loggers, and leak detectors. The company, founded in 1977 and headquartered in Amherst, NH, meets International Organization for Standardization (ISO) standard 9001:2008.
