Mountz 068404 (LTT250i)

LTT250i Torque Analyzer (25-250 lbf.in)

Add to List

The LTT 250i torque analyzer is used for torque testing and calibrating tools. The digital torque analyzer can test hand screwdrivers, torque wrenches and power torque tools. The instrument features a built-in transducer and has the flexibility to connect to an external torque sensor to expand testing capacity and process. The LTT unit allows you to record and store torque testing data for conformity with quality standards and conduct data analytics.

  • Recommended for all hand screwdrivers, wrenches, or power tools
  • Provides EZ-Plug & Play with Mountz torque sensors. Features ARCII technology, an instant auto-recognition system of the sensor connected to the LTT
  • Features a built-in transducer and can connect to an external torque sensor
  • Selection of six operation modes: (Track, Peak, First Peak, Audit, Spindle Audit and Torque + Angle)
  • Seven units of torque measurements: (ozf.in, lbf.in, lbf.ft, cN.m, N.m, kgf.m, kgf.cm). Two units of force measurements: (lbf and kN)
  • Features built-in tool tests operation
  • Stores a total of 5000 data points
  • Real-time clock for time stamping of readings. USB interface to download readings to PC
  • Real-time graph of torque vs. time using associated PC Windows software
  • Features Go / No Go LEDs that illuminate when the high or low setting is achieved
  • Run Down Adapter (RDA-10i) is included with LTT10i. Use the RDA when testing and calibrating power tools.
  • Easy-to-use menu structure, a six-digit display and connect to an external torque sensor
  • High capacity Li-Ion batteries for long life (30 hrs with standard torque sensors and 16 hrs with brushless rotary sensors)
  • Can connect to most mv/v torque sensors and can store calibration data for up to 50 non-smart torque & force sensors
  • The 5VDC capability allows the unit to be used with a Brushless Rotary torque sensor for testing pulse tools and high RPM tools
  • Torque and Angle data is displayed simultaneously when used with Torque and Angle sensors, up to 8000 RPM for angle measurement
  • Display Accuracy is better than +/- 0.0625 of reading
  • Five low-pass filter selections (3000, 2000, 1500, 500 and 200 Hz)
  • "Flash" memory allows upgrades to be done by the user in the field & internet through the USB port
