80/140/200m Dual-Laser Calibration Laser Rangefinder Module - LRFX0M20PD
The LRFX0M20PD is a high-precision laser rangefinder module featuring a dual-laser calibration design. This design eliminates environmental interference and electronic system errors, offering greater stability and accuracy compared to standard single-laser rangefinder modules. The dual-laser calibration includes a closed-loop feedback circuit, which resolves feedback issues common to open-loop systems and reduces measurement repetition errors. These advantages enable the LRFX0M20PD to maintain absolute accuracy across varying environmental conditions.
Please note that the LRFX0M20PD is designed for indoor measurements of static targets. This module prioritizes providing accurate measurement results, so its frequency will decrease or may not provide results when measuring moving targets or objects with lower reflectivity. In such cases, you may consider Dynamic Dual-Laser Calibration Laser Rangefinder Module.
