Log Master II Torque Logger Unit Model 8090

Display and record your torque on our Log Master II touchscreen and automatically create data reports.

  • Description Description

These automated data logging devices operate in the harsh environment of a workshop. Log Master II units may be safely and efficiently operated by one person from the hydraulic console on the jar tester machine or TorqueMaster™ units. All functions of the Log Master II logger are easily accessed by using an industrial-grade touchscreen. The Log Master II logger can also be used to log on to our jar testers. It is available for both standalone jar testers (model 8090-B-57) and for jar testers with a TorqueMaster unit (model 8090-B-514).

The Log Master II controller/logger displays and records torque and automatically creates a tool report in PDF that includes connection-specific information and a torque-versus-time plot. The Log Master II unit features enhanced operator usability with a customizable graphic user interface to match workflows. The supervisory software used with the Log Master II controller/logger takes advantage of an office computer to handle the many functions associated with the creation of tools, job files, and data management of logged jobs.
