TNP Torque Meter TesterDigital Torque Meter

The Series TNP Digital Torque Meter is a precision instrument for measuring OPEN and CLOSE torque values for various applications. The TNP

Torque Meter is used in medical, pharmaceutical, industrial quality control, R&D and countless other torque applications. As a cap torque analyzer, the TNP repeatedly determines bottle closure and breakaway torque. Its wide memory capacity is capable of storing 1,000 data points, including Average, Maximum and Minimum values. A HI-GO-LO LED comparator feature can be utilized for large batch testing to ensure overall product quality.

The TNP is a portable device powered with internal rechargeable batteries or through provided universal AC adapter/charger. Designed with a small footprint, it can easily be transferred between the shop floor and laboratory taking up little space when operating. The TNP Torque Meter comes standard with USB connection and cable for easy PC/Software interface. Combined with the free “DIGITORQ” Software, statistical testing, graphing and analysis can be performed.
