With additional storage capability, peak detection for screw caps with tamper evident ring, and external USB storage in CSV data format

Alluris TMI-300 Digital Torque Meter with USB Output are employed for quality control in industrial sectors and laboratories. The robust measuring cell combines high accuracy with a very high overload protection, and it functions bidirectional.

Thus, torque into both directions can be collected. The measurement values are shown in the central display alternatively in line with the SI system in newton-meter, newton-centimeter, or in the derivative units of weight.

In order to detect accurate and reproducible peak values during the course of rotation 1000 measurement values are collected per second. During a measurement, actual values and the respective peak value can be displayed alternatively. The instrument possesses a data memory, in which up to 1000 single values can be stored and statistically evaluated.

The TMI-300 model offers a very good cost/performance ratio; its major advantage is its simple and safe application while being highly accurate at the same time.
