Highlights

Miniaturized Design:With a groundbreaking structural design, its volume is reduced by over 70% compared to the earlier models, setting a new benchmark for a portable instrument for vibration measurement.

Dual Laser Indication: Adopting a 1550nm safe measurement laser and a 635nm red visible indicator light, it enables easy, fast, and safe alignment with the target to be measured.

Wide Frequency Band & High Resolution: It supports ultra-wide frequency range measurement from DC to 100kHz, with an amplitude resolution of up to 8 picometers (pm), capable of accurately capturing weak vibration signals from ultra-low to high frequencies.

Non-contact Measurement:Laser measurement requires no contact with the object surface and causes no additional mass influence, making it particularly suitable for thin, light, or hard-to-contact objects.

Easy Operation:It features simple power supply (DC 12V) and low power consumption (<8W), and can be connected to a mobile power source or vehicle-mounted power supply, facilitating outdoor and on-site uses.

Excellent Environmental Adaptability:With an IP54 protection rating, it effectively resists dust and water splashes, meeting the needs of various industrial on-site environments.

Core Advantages

Ultimate Portability for On-the-Go Vibration Measurement: Weighing only 800 g (l.76 bs) with a compact size of 177×96×52mm (7.0×3.8×2.0 in), the device can be easily held by hand or integrated into small spaces. It completely frees users from the larger sizes of other vibrometers, enabling precise measurement anytime and anywhere.

Outstanding Performance with Consistent Precision: With its compact body, the LV-M300 maintains the consistent high-performance standards of SunnyInnovation's products. Equipped with picometer-level (pm-level) resolution and megahertz-level (MHz-level) frequency response, it ensures accurate and reliable measurement data.

Superior Cost-effectiveness: While guaranteeing core performance, the LV-M300 significantly optimizes costs through an innovative design. It offers an entry-level price paired with professional-grade user experience, making it an ideal choice for taking the advantages of latest vibration measurement technology.
Fully Home-grown Silicon Photonics Technology Platform: It adopts the independently developed silicon photonic chips and achieving highly integrated optical path systems from SunnyInnovation innovation.
