The versatile ILTT Inline Torque Tester converts any non-impacting tool into a complete torque measuring & analyzing system, simply insert the tester between the tool and what it’s driving and measure clockwise or counter-clockwise torque. The ILTT It can also be used for many other in-line torque measuring applications including measuring valve torque, actuator torque and more. Drive sizes can be custom built with splines, key-ways and other design features to suit your application. Contact us to review your needs.
Internal NiMH rechargeable batteries provide 8-10 hours of continuous use.
The ILTT features an easy-to-use menu allowing fast adjustment of test parameters and works in either one button or automatic modes of operation. Reliability and ease of use are enhanced with features such as; Sign Lock, Peak Blanking and Auto Clear.
Not for use with Impact Tools.
