This professional digital cable height meter adopts ultrasonic principle to measure cable height with fast and accurate readings safely and quickly. It's widely used for measuring the distance between wire and wire in different uses of cables. Features: Wide cable height measurement range(25mm cable min): 3-23mm for measuring the height up to 6 cables together. Wide horizontal measurement range: 3-18m, for measuring the distance between wire and wire. User friendly and easy-to-operate Ultrasonic Cable Height Meter, applicable to different use of cables. Adopts large measuring sensor for higher accuracy than other cable height meters and measuring the distance between objects. Digital backlight LCD display, easy to aim at the measuring position and convenient to read in dark. The temperature compensation enables the meter compensates error automatically under -1040 and ensures the measuring accuracy on differnet temperature conditions. Can be used for depth measurement with the accessory bracket, (examples: an elevator shaft or well) provided there is sufficient width to permit a proper ultrasonic reflection. Can be widely used in electrical, overhead cables, tree branches, forestry, industrial, mining, elevator shafts, depth of wells, etc. Specifications: Brand Name: SMART SENSOR Color: Yellow Material: ABS Plastic Display: LCD Backlight Display Screen Size: 52 * 26mm / 2.05 * 1.02in Measuring Range: Range(25mm Cable min): 3 23m Range(12mm Cable min): 3 15m Range(5.5mm Cable min): 3 12m Range(2.5mm Cable min): 3 10m Horizontal Measuring Range: 3 18m Resolution: 5mm(Range10m) Accuracy: 0.5%2dgt Minimum Gap Between Wires: 150mm BOT Mode: Measuring the Height of the Lowest 6 Cables TOP Mode: Measuring the Height of the Highest 6 Cables Auto Power Off: Backlight Display: Battery Indication: Imperial & Metric Units Transition: Real Time Temperature Display: Auto Power Off Delay: 120s Operating Temperature: -1040(14104) Storage Temperature: -2060(-4140) Operating Humidity: 10% to 95% RH,
