SEFAR Tensocheck 100 on zeroing plate

In comparison to commonly used, spring loaded tension meters, the SEFAR Tensocheck 100 has significant performance improvements:

Measurement precision


Measurements above 30 N/cm are displayed with 0.5 N/cm resolution. A finer resolution (0.2 N/cm) is used below this figure. SEFAR Tensocheck 100 enhances the reproducibility of the screen tension.

Wide display range


SEFAR Tensocheck 100 covers the range of 4 to 60 N/cm, making it valuable measurement tool for every application and mesh specification.

Optional, certified calibration plate

Optional control plate


An optional control plate is available for the SEFAR Tensocheck 100. The control plates come with certification required by ISO quality systems. The control plate allows customers to check calibration of their SEFAR Tensocheck 100 internally, in comparison to sending it out to an external calibration service provider.

Zero adjustment


The instrument comes with a zeroing plate for quick confirmation, or adjustment simply by pressing a button. This provides repeatable results every time you use the tension meter.

Large, digital display

Digital display


The digits of the measured values are 10 mm in size, and appear on a clear, digital display that is highly legible even at a distance.

Selectable measurement units


Select between N/cm and millimeters at the touch of a button. The measuring options make SEFAR Tensocheck 100 usable anywhere in the world.

Automatic shut-off


After three minutes without measurement activity, the device shuts itself off to conserve battery life.

Operation


SEFAR Tensocheck 100 can be used and operated without any special expertise.

The high sensitivity of the TetkoMat 10-100 allows measurement control of tension variations within a screen regardless of frame size.

Features of the TetkoMat 10/100:

Substantial improvement in tension measuring methods as compared to touch control, gauging by percentage of fabric elongation, and air pressure values.

Accurate tension measurements will improve registration and reduce rejects, resulting in increased productivity.

Reproducible and uniform tension measurements, screen after screen.

An affordable production aid for all sizes of operations.

Ideal for high volume, multiple screen making stations where more than one TetkoMat 10-100 is required.
