Lab Expo Mullen Burst Tester 61-PPT125 is used to measure the bursting strength of paper submitted to increasing hydraulic pressure. Used in testing bursting strength of all types of papers in the 0 to 1600 kPa range depending on clamp pressure. It has mechanically & electrically integrated modern design, with compact structure & easy for maintenance. The advantage of user-friendly operations, stable performance makes this tester an essential instrument for papermaking, packing, inspection and research.
