Elcometer 1720 Abrasion Scrubbing
Washability Tester

This robust, reliable and extremely flexible machine has been designed for testing the washability, brushability and abrasion resistance of a wide range of materials, including; paint, lacquers, inks, coatings, leather, wood, plastics, printed material, fabrics, etc.

The Elcometer 1720 is available in two versions:

• 2 working stations - undertakes two tests at the same time.

• 4 working stations (as shown in picture) - allows the operator to test up to 4 samples, or 4 different tests at the same time, dramatically increasing your productivity.

A kit is also available - allowing you to upgrade your 2 working station model to a 4 working station model

Simple to use and adaptable, the Elcometer 1720 has a large amount of functionality built in, including:

• Double Counter - Double function and independent displays make it easy to repeat and follow test sequences:

• pre-selection count function - set the number of cycles desired per sequence and leave the machine to automatically stop.

• total count function - indicates the total number of cycles after one or several sequences.

• Variable Speeds - with two interchangeable operating modes, the machine's performance can be optimised according to the type of tests:

• fixed speed mode - 37 cycles per minute (ASTM, DIN, ISO and EN test methods).

• variable speed mode - the operator can select a speed from 15 to 65 cycles per minute. (1 cycle = 1 motion back and forth of the carriage).

• Carriage - the carriage is designed with multiple functionality:

• adjustable stroke length - user defined stroke length from 30 to 290mm.

• test tool locator - the brushes or abrasive pads are located in the chambers and are guided without superfluous devices or mechanisms, making it easy to install or remove alternative test tools.

• Individual Dosers - using this device the flow of test liquids can be regulated for each test location, independently.

• Rapid Specimen Fastening System - aluminium frames are held in place by quick release clamps. Each frame is fitted with a gasket which both enclose and divide the test specimen - allowing effective and comparative tests to be carried out simultaneously.

• Chassis - made from thick anodised aluminium, the Elcometer 1720 is both self supporting and robust, giving complete confidence in the durability of the machine, no matter how long the test period.

The Elcometer 1720 is equipped with either 2 or 4 working stations, each path separated by a water-tight gasket frame. This design enables up to 2 or 4 simultaneous comparative tests to be carried out. Dimensions are adapted so that 2 strokes of different products can be positioned onto a same specimen, e.g. PVC Leneta test panel. As a result a substantial economy of consumables can be achieved. For this purpose, the optional Elcometer 3508/1 2 Reservoir Film Applicator facilitates the sample preparation.
