The Parotester 2 roll hardness tester provides accurate and reliable evaluations of the roll hardness, hardness profile and hardness variation of paper, foil and film rolls. With Proceq’s roll hardness tester, unevenly wound reels can be spotted prior to interruption of operations and cause of quality problems in printing and converting operations.
By taking Leeb readings across the roll, uneven, too soft or too hard winding can be detected and the roll can be rejected. This minimizes the risk of complications e.g. during the printing process on paper.
Automatic loading and unloading of the impact body by pressing the impact device to the roll as implemented in the Parotester 2 roll hardness tester results in fast and repeatable tests of greater resolution than the commonly used Original Schmidt type L hammer tester.
Proceq SA is committed to the manufacturing of quality nondestructive portable testing instruments for concrete properties and structural parameters, metal hardness and paper roll hardness. The company’s strong Research and Development team continues to create products that set standards in these industries. Since 1994, Proceq has been certified to the ISO 9001 standards that guarantee the quality of processes, products and services.
From the beginning, Proceq has been delivering ground-breaking solutions to the industry. In the 1950s, the company became the producer of the original “Schmidt Hammer” (known as the “Swiss Hammer”). This innovative tool utilizes the world’s first patented non-destructive testing method for concrete properties. Another Proceq classic was released in the 1970s with the “Equotip” metal hardness tester. The instrument is based on the Leeb rebound principle which was invented by Proceq. In the following years, the company kept adding advanced products to their portfolio, such as the Canin Corrosion Analyzing Instrument, the Profoscope Rebar Detector and Covermeter, the SilverSchmidt Concrete Test Hammer and the PaperSchmidt Roll Hardness Tester. In order to offer their customers a broader range of products, Proceq acquired the UK based company CNS Farnell Ltd., the producers of the world’s most trusted instrument for ultrasonic concrete testing - the “Pundit”.
Proceq SA was established in 1954 in Zurich, Switzerland. To provide their international customers with local support, Proceq continually increases its presence through subsidiaries in Asia (Singapore), China (Beijing and Shanghai), Europe (London, Zurich), the Middle East (Dubai), Russia (St. Petersburg), South America (São Paulo), the USA (Chicago, Pittsburgh) and through a global network of agents and partners.
