ST-5000 (ST-5100) portable LED stroboscope with automatic speed-detection laser and 21 high-power CREE LEDs: the detected speed is converted directly into the flash frequency, making it simpler to use.
- Auto-speed laser: flash frequency set automatically
- Array of 21 CREE LEDs: bright, stable light
- Range 30–120,000 FPM: 0.5–2000 Hz
- Accuracy 0.01%: ±1 digit F.S.
- Lithium battery: up to 5 hours of battery life
- External sensor input: synchronisation with the process
- CE, RoHS: 1-year warranty
The ST-5000/ST-5100 is a portable LED stroboscope for the non-contact inspection of moving parts. Its distinctive feature is the automatic speed-detection laser, which converts the measured speed directly into the LED flash frequency, greatly simplifying operation.
The array of 21 high-power CREE LEDs ensures bright, stable light over a wide measuring range, with a long service life compared with xenon. The rechargeable lithium battery provides up to 5 hours of operation; adjustment with x2/÷2 keys and fine tuning, external sensor input, backlit LCD display. ABS housing, 280 g, 228 × 86 × 40 mm.

Completed and documented applications:
High-speed optical analysis
Portable xenon and LED stroboscopes optically “freeze” the repetitive motion of high-speed objects, allowing visual inspection, quality control and the analysis of rotating parts and machines in production without stopping them.
Speed measurement and preventive maintenance
Stroboscopes measure rotational speed without contact and support preventive maintenance: by observing belts, pulleys, gears and rotating parts as still images, wear, play and anomalies are spotted before a failure occurs.
Frequently asked questions
The ST-5000/ST-5100 adds an automatic speed-detection laser that sets the flash frequency directly according to the measured speed, making it simpler to use; otherwise it shares the array of 21 CREE LEDs and the performance of the ST-4000.
From 30 to 120,000 FPM (0.5–2000 Hz), with an accuracy of 0.01% ±1 digit of full scale.
The rechargeable lithium battery provides up to about 5 hours of operation; it can also be powered from 100–240 VAC mains.
Speed and frequency measurements and analysis of motion and vibration in predictive maintenance: motors, shafts, printing, extrusion, fans, gears and more.
