Mar Tester acc. to Oesterle Model 435 - ERICHSEN

The Mar Tester 435 S, developed in collaboration with leading manufacturers of vehicle cockpit scaled indication fittings, represents a pinnacle innovation in adhesion testing and scratch resistance evaluation. This advanced instrument is specifically designed to assess the durability and adherence of colored coatings, such as those found on speedometer dials, to their substrates under the action of a blunt test body with a defined force.

Advanced Design and Functionality

Distinguished by its unique test body movement, the Mar Tester 435 S offers precision testing by sliding laterally, contrasting with the longitudinal scar-producing movement of its predecessor. It caters to a broad spectrum of printed scales, letters, and marking tests, offering manufacturers a versatile tool for comprehensive quality assurance.

Robust Testing Methodology

Equipped with a steel-made test disc and variable force settings ranging from 0 to 20 N, the Model 435 S ensures reliable adhesion and scratch resistance testing across various surfaces. Whether assessing raised inscriptions or evaluating the resilience of coatings against blunt effects, this tester provides accurate, quantifiable results.

Inclusive Delivery Scope

Each unit includes the core Adhesion and Resistance Tester Model 435 S, a steel test disc, three force springs for customized testing, and a carrying case. Additionally, the ERICHSEN SmartPen introduces a new era in mobile scratch hardness testing, enhancing the testing capabilities for on-site and in-lab evaluations.
