Features & Benefits Digital display Motorised opening Working ranges: -10°C to +200°C (14°F to 392°F), or to +100°C (212°F), 10 to 95% RH, depending on equipment Applications Selection of pigments, binders, solvents etc. which can develop the lowest minimum internal stresses Establish paint compositions with optimum durability Study film formation Examine the effects of ageing on the development of internal stresses

Developed in conjunction with the Coatings Research Institute (CoRI), the Elcometer 8300 has been developed to measure internal stresses in organic coatings, not only during the drying phase, but also when a coating is placed into operation, where temperature and humidity variations can cause hygrothermal stresses and impair its durability.

The principle is based on measuring the bending of a calibrated plate, coated with the product to be examined. Under pre-determined temperature and humidity conditions, the deflection is measured by a micrometric sensor.

The Elcometer 8300 has programmable measuring period from 1 second to 99 hours and several possible configurations: manual or automatic by cyclic programming, for recording on printer or computer.
