1. INTRODUCTION:
Paper Mit Folding Endurance Tester (PN-NZ135F) is a new type testing instrument to test Paper's Folding Endurance, which is designed to be in accordance with related national standard GB/T 2679.5-1995, Paper and board-Determination of folding endurance (MIT Tester). PN-NZ135 MIT Paper Folding Endurance Tester has various functions, such as, parameter testing, parametric transformation, parameter regulation, parameter display, parameter memory and parameter print. The tester has data processing function which can directly output result of statistical data with convenient operation, easy regulation and stable performance. The main functions are shown as following: compact structure, light weight, abundant functions, horizontal type and stable performance, so the tester is suitable for different paper and boards.
