The BikeMaster Digital Torque Wrench Adaptor has an easy-to- read LCD screen, signal LED light and alarm. It features a built-in memory that stores the last 50 torque value readings as wellas Peak and Track modes to log highest torque achieved. The automatic shut-off extends the life of the battery. Complete with a durable protective carrying case, its compact design takes up less room than conventional torque wrenches.
