DRK108B Electronic Tearing strength tester

Product introduction

DRK108B Electronic Tearing Strength Tester is the special
instrument for tearing strength test. In paper making industry,
packaging industry, science and research industry and supervision
and inspection industry, it is necessary.

Product features

1. Mechatronics and compact structure design, to ensure the elegant appearance, also easy to
maintain.
2. Adopt high precision AD converter(resolution is 1/10,000,000) and high precision angle sensor
to ensure collecting the data fast and correct.
3. Equipped with Micro-printer, convenient to print the report.
4. Connect to computer, to display the curve, also can analyze, save, print the data.
5. The configuration is very flexible, to reach different functions.

Product application

Appling in testing paper tearing strength.
If change the configuration, it can be used to test other materials, like plastic, chemical fiber, metal wire, metal foil and so on.
