The Monarch 6235-010 PLS pocket LED stroboscope has internal and external modes, time delay, phase shift, and a NIST Certificate of Calibration, and provides inspection and speed measurement. It is designed for motion analysis, preventive maintenance, printing inspection, and speed measurement of repetitive motion. The 7-array LED light source has a light output of 1800 lumens at 6000 flashes per minute (FPM) eight inches from the lens. Adjustable flash duration of 0.1 to 18 degrees or 0.5 to 2500 microseconds. LED lights have a longer bulb life and require less energy than xenon flash tubes and can extend the battery life of battery-powered stroboscopes, have a lower heat output, and quieter operation when used in audio testing. The internal flash mode has a range of 30 to 300,000 FPM and 0.5 to 5,000 hertz (Hz) and has an accuracy of 0.005% of setting, or + or - last digit. The external flash mode has a range of 0 to 300,000 FPM, 0 to 5000 Hz and accuracy of + or - 0.005% of reading, or + or - last digit. A NIST Certificate of Calibration ensures accuracy. Built-in multiply-by-2 and divide-by-2 functionality allows the operator to distinguish true RPM from harmonics. Separate 3.5mm (1/8") transistor-transistor logic (TTL) input and output jacks provide power to remote sensors and allow multiple strobes to be daisy-chained to provide wider coverage. Tachometer mode, available for use while the stroboscope is in external mode, has a measuring range of 30 to 300,000 rpm (requires remote sensor, not included). Phase shift of 0.1 to 18 degrees of rotation and time delay of 0.5 to 2500 microseconds allow operator to manually adjust the focal point of the object to any point in the rotation without moving the trigger point. A continuous duty and integrated 1/4" - 20 UNF (Unified Fine) thread mount enables the stroboscope to be used continuously over the life of the battery. Five user-selectable flash rates can be programmed into the device and recalled after powering off. The stroboscope is powered by 3.6V DC internal rechargeable lithium-ion batteries with an average run time of 5 to 6 hours between charges. The stroboscope includes universal 115/230V AC battery charger with interchangeable wall plugs, a NIST Certificate of Calibration, and instructions. It is RoHS compliant and CE marked. 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.
