Crane ReadStar TT

Capacity 0.5 / 1 / 4 / 12 / 30 Nm

The new and improved ReadStar TT torque tester from Crane Electronics is ideal for the concise measurement and collection of assembly tool torque audit data within manufacturing and quality environments.


The basic, easy-to-use readouts include a built-in torque transducer and has a variety of measurement modes including track, peak, pulse and click. The ReadStar TT can be used as a portable device or fixed permanently using the mounting bars.


The new and improved torque tester incorporates a bigger and clearer OLED screen display to view readings and results and the redesigned, easy to use keypad offers a familiar feel with simple function keys to effortlessly switch between modes and settings.


The new internal memory now allows for a massive 999 readings to be stored and the addition of a new micro USB port allows for a wider range of connections for printing and exporting data. The new port also allows for additional power options alongside the general 5V power supply and internal battery option for added portability.


For optimal power management, the ReadStar TT automatically switches to the highest voltage power source to save on battery life, yet still giving the option to pick it up and unplug to seamlessly run on battery power.


The ReadStar TT is supplied with a built-in transducer and a standard rundown adapter, and is available in 0.5Nm, 1Nm, 4Nm, 12Nm and 30Nm ranges. A premium joint kit is also available, sold seperately.
