Measure rotational speed using flicker frequency analysis. Adjust frequency with precision up to 1000 Hz. Detect stationary motion by matching flicker rates. Control connected flashlight for testing. View frequency and RPM values in real time.
Allows users to check horizontal and vertical alignment. Features include circle mode for simultaneous angle measurement, vertical mode for ensuring surfaces are straight, horizontal mode for flat surfaces, and mix mode combining all functions.
Measure noise levels using a precise . Record levels and view real-time data. Set thresholds and receive alerts when limits are exceeded. Export measurements and share results.
Measure wheel alignment with total toe and thrust line comparison. Adjust front and rear toe angles. Sync measurements with a precision toolkit. Export data for record-keeping. Perform alignments without specialized equipment.
Measure altitude using barometric pressure and GPS data. Display altitude in feet and meters with real-time accuracy. Calibrate sensor and switch between day and night display modes.
Measure screen ripple and select eye-friendly devices
Measure ripple coefficient of light sources including LED, halogen, fluorescent, and incandescent lamps, as well as LCD and LED monitors. Display readings for visible spectrum radiation. Note that results may vary based on light source and frequency.
Visualizes time by simulating , where numbers fall and are buried as time passes. Users can watch the face change dynamically with each second. The offers a realistic physics-based animation of time progression.
Measure angles with horizontal, vertical, and dual-axis guides. Use bubble and circle levels for precise alignment. Set custom zero points for relative measurements. Lock readings for easy recording. Display real-time degrees and visual indicators.
Measure environmental levels in real time using your device's microphone. Display readings accurately. Detect and monitor sound levels at home, work, or outdoors.
