Benefits at a Glance
· The double-walled bath technique features a very even and exact temperature accuracy of ±0.2 °C. The fully insulated, isothermal bath jacket is connected to an external thermostatic circulator (optional) for tempering.
· Automatic rupture detection above a force of 20 mN
· Exact temperature recording during the test run period by three sensors allocated across the bath length
· Minimum tensile force margin setting: When a briquette ruptures and the tensile force falls below this setting, the pertinent elongation is stored. When all three briquettes are broken, DDA 3 stops automatically
Convenient Operation
· The ductility meter is a microprocessor-controlled stainless steel test bath with illumination, several temperature probes and transparent acrylic bath cover. The stepping motor drive and feed rod are located outside the tempering bath and are therefore not affected by corroding influences of the bath liquid. If extremely thin threads are measured, the built-in circulation pump for the inner bath can be switched off.
· The control unit for setting test parameters and the digital display of measured values such as traction speed, tensile force, distance and temperature is placed in a separate housing and serves as a stand for the printer that records test parameters and measured values.
