the 1531AB Strobotac Electronic Stroboscope is a later version of the 1531A. It is a small portable unit used to measure speed of fast-moving devices. The 1531AB weighs less (~1 lb less) than the previous 1531A but offers the same capabilities and specifications. Flashing rate range of 110 to 25,000 flashes per minute.
The GenRad 1531-AB Strobotac electronic stroboscope includes a strobotron lamp and reflector assembly, an electronic pulse generator that controls the flashing rate, and a line-operated power supply. The flashing-rate range of 110 to 25.000 flashes per minute is divided into three direct-reading ranges; toavoid reading errors, only the particular range in use is illuminated. The rpm control is concentric with the range selector, and its large diameter provides precisecontrol of the flashing rate. The flash lamp can be triggered externally to "stop" motion for photography. The combination of the Type 1531-P2 Flash Delay and the Tyte 1536-A Photoelectric Pickoff can be used as an external triggering source, which also provides an adjustable delay of the stroboscope flash with respect to the triggering pulse from the photoelectric pickoff.
A built-in calibration system within the GenRad 1531 Stroboscope uses the power-line frequency for quick, easy check and readjustment of the flashing-rate calibration. The strobotron flash lamp and reflector assembly pivots in a plane perpendicular to the panel and swivels 360 degrees on its own axis. The case is equipped with 1/4 x 20 socket for mounting the instrument on a tripod
High-intensity flash for a stroboscope - up to 18 million beam candles (peak) for a single flash.
High flashing rates up to 25,000 per minute - speed measurements to 250.000 rpm.
Short flash duration - "stops" rapid motion and permits ultra-high-speed photography.
High accuracy stroboscope - rpm measurements can be made to +/- 1%.
Convenience -small Flip-Tilt case and swivel-mounted lamp.
Many U.S. government military and regulatory agencies specifically call out and/or reference these strobes. These products continue to be built and serviced in the Genrad tradition
