HL-03

Rugged aluminum alloy housing and durable high-strength
  forged steel molded load cell 
• Bright red LED and easy to read 58.4mm(2.3") display
• With the full-scale calibration and 5-point inspection of a
   professional weight machine (up to 20 tons),above 25 tons
   has passed the "accuracy test" of the tensile testing equipment;
   the weight is accurate and reliable
• Non-screw connections between the upper ring, load cell and
   bottom hook to avoid loosening or breaking
• The ultimate safe overload of the HL series is at least 500% of
   the scale capacity. The 50-ton crane scale passed the maximum
   175-ton (350%) test of the tensile testing machine without any
   deformation or damage. (Under laboratory static strength
   tensile testing)
• 260 hours of continuous use after full charged
• Patented structural reinforcement design of the load cell to
   maximize the protection of the load cell from failure due to
   overload
• Keypad function : ON/OFF, LOCK, CHANGE, ZERO
• "Remote control" for convenient wireless operation, distance
   20 meters (included)
• Low battery and charging indication
• 100% developed and manufactured in Taiwan
