Intrinsically Safe Laser Distance Measuring Instrument with 300 Meters Range and No Reflective Plates Required for Mine Use

This instrument is designed for mining environments including underground coal mine excavation work surfaces, return airways, and electrical machinery chambers. Engineered with high-performance chips, it delivers long-distance measurement capabilities up to 300 meters without requiring reflective plates. The integrated telescope facilitates target location even when the laser point becomes invisible at extended ranges. Key attributes include simple operation, easy maintenance, excellent sealing performance, and high safety reliability.
