TechStrobe Digital Stroboscope

The TechStrobe from Sticht is the perfect tool for slow motion, or stop action stroboscopic inspection. The Sticht TechStrobe is the only palm size unit to include a Phase shift feature. Phase shifting allows the TechStrobe operator to advance or retard the flash timing by degrees° of angle, without changing the actual flash rate (FPM) of the TechStrobe.

Employing its unique Phase shifting feature, the TechStrobe “freezes” rotating or reciprocating machinery for visual inspection of covered gear teeth, shafts, oil/fuel/ink injector patterns, and print media; all without stopping production.

The TechStrobe is completely portable and operates up to 2.5 hours at 1600 FPM from its detachable, rechargeable battery. The ergonomically designed battery serves as the padded grip area. The battery is quickly detached and recharged while another battery is snapped into place.

Designed for right or left hand, all TechStrobe functions are intuitive and easy to use. Quality and Maintenance Professionals will appreciate the rotary and push button controls for internal flash (FPM/RPM) control, external triggering, tachometer mode and Phase shift control. The push buttons rapidly increase (x 2), or decrease (÷2) the flashes per minute (FPM) and change by degrees° the Flash phase.

Compact, impact resistant and rugged, with that balanced feeling for one-handed operation, the TechStrobe will quickly become one of the Quality and Maintenance Professionals’ favorite tools.

Nova Strobe Digital And Analog Stroboscopes

These economical strobes are available either electrically or battery powered. Battery models weigh only 40 ounces and have internal rechargeable batteries so there is no cumbersome external battery pack to carry. Recharging takes only 3 hours and they will operate for a full 60 minutes at 60,000 flashes per minute after charging. They feature a low battery indicator and automatic shut-off.
More than 20% brighter than many other models, all strobes use a high intensity xenon flash tube. Both analog and digital models have back lighted displays for easy reading under all conditions. Accuracy is *2% of setting. Strobes have TTL compatible input and output jacks on digital models that allow them to be remotely triggered and synchronized or operated in a master/slave configuration.
