Our team recently conducted comprehensive performance testing on the 1500m laser rangefinder module to ensure its reliability and accuracy under various conditions. The testing process involved evaluating key parameters such as ranging accuracy, maximum and minimum distance capabilities, and response time. Using calibrated targets at different distances, we measured the module's precision, which consistently met the specified accuracy of ±1m. Additionally, we tested its performance in extreme temperatures, ranging from -20°C to +60°C, to confirm its stability in harsh environments. The module's low standby power consumption (≤0.4W) and ability to achieve zero power consumption when powered off were also verified. Throughout the testing, the 1500m laser range finder module demonstrated excellent reliability, high precision, and robust performance, making it suitable for applications such as handheld devices, UAVs, and small gimbal camera. Our rigorous testing ensures that the 1500m laser rangefinder module meets the highest standards of quality and performance.
