In the world of precision measurement, accuracy and reliability are paramount. As a premier laser distance meter factory, HOLO Precision Instrument has established itself as a leading manufacturer with over 15 years of experience in designing and producing cutting-edge measurement tools. Our commitment to “high performance, high quality, and high value” drives every product that leaves our facility, serving industries ranging from construction and interior design to fire emergency and engineering surveying across more than 20 countries worldwide.
The Power of Angle Measurement
What sets HOLO laser distance meters apart is their sophisticated angle measurement capability. Our devices, including the popular D series, are equipped with advanced inclination sensors that enable a comprehensive range of angular functions. This feature transforms a simple distance meter into a versatile surveying instrument capable of:
● Inclination angle measurement
● Horizontal and vertical distance measurement for complex layouts
● Height difference calculation without climbing or reaching
● Indirect measurement via Pythagorean functions to determine distances that are physically inaccessible
Uncompromising Accuracy and Performance
HOLO laser distance meters utilize phase-based laser ranging technology, a sophisticated method that modulates laser frequency and measures phase differences to deliver millimeter-level precision. With measurement ranges available from 30 to 120 meters and accuracy of ±1.5mm /±2mm, our devices provide reliable data that professionals can trust.
Our comprehensive series—including the E, X, Y, RG, R, D, P and G lines—offers diverse configurations to meet varied application needs. Key technical specifications include:
| Feature | Specification |
| Measurement Range | Up to 120 meters |
| Accuracy | ±1.5mm/±2mm |
| Laser Class | Class II |
| Laser Diode | 635nm, <1mW |
| Battery Life | >10,000 measurements |
Built for Real-World Applications
From fire emergency response to construction stakeout, HOLO distance meters are engineered for demanding environments. The angle measurement function proves invaluable in scenarios such as:
● Fire scene safety assessment – measuring fire point height and safe distances quickly and accurately-1
● Architectural layout – calculating spans between any two points in space
● Interior design and renovation – taking indirect measurements around obstacles
● Large equipment installation – ensuring proper alignment and positioning
Factory-Direct Quality and Value
As an original manufacturer, HOLO offers a distinct advantage: premium direct supply without middleman markups. Every unit undergoes rigorous quality control, including calibration and extreme-condition testing for drop resistance, waterproofing (IP54), and temperature stability. Our OEM and ODM services provide flexible customization options, from measurement ranges to data interfaces (Bluetooth) and private labeling.
Conclusion: Precision You Can Count On
