TNC Series Torque Cap Tester

The TNC Digital Torque Cap Tester is a simple operation test instrument for quickly measuring Open and Close torque values up to 14.8 ft-lbs (20 N-m) on a wide range of test samples with diameters ranging from 0.77" (19.5 mm) to 7.48" (190 mm). The TNC meter is used in medical, pharmaceutical, industrial quality control, R&D and countless other torque applications.

The TNC's provide long operation life and power flexibility with the ability to work from the internal rechargeable battery or included AC adapter. The TNC's have six modes of operation: Track for live readings, Peak which records the highest level over a test, First Peak which records a reading after a programmed decrease, Auto Peak which resets after a period of time, Auto First Peak which resets the first peak after a period of time, Double Peak which provides two separate peak readings from programmed decreases. Preset operation with programmable tolerance thresholds for a quick pass/fail test is available in all modes.

The analog bar graph on the backlit, reversible LCD aids users by providing the resultant torque's current position compared to the full-scale range along with the direction of the force. Pass/fail icons produce live test feedback allowing instant determination of the results.

Every tester comes standard with USB and RS-232 outputs. The TNC's software enables the uploading of data and the additional statistical analysis with its auto-calculation of the selected values. These excellent features make the TNC Torque Cap Testers a valuable and versatile addition to the production, R & D and quality control departments.
