Its broad counting range from 0 to 999,999 ensures high precision across both short and long distances Pre-Set Alert Measurement】: Set your desired measurement value in advance, once the measured distance reaches your defined value, the device emits a clear prompt sound. This smart reminder helps prevent over- or under-measuring, enhancing workflow accuracy Dual Relay Control】: Equipped with two independent relay outputs (AL1 and AL2), this meter can control two separate machines or devices at the same time within one production line, This streamlines automated processes, improves coordination, and boosts operational efficiency Smooth Rubber Wheel Sensor】: Features a single rubber-coated wheel with a smooth surface and 200mm circumference for stable, consistent rolling. Its quiet operation reduces noise, while forward/reverse rotation intuitively adds or subtracts measured length Service ：We value your shopping experience!
