The ETC Viewer
The ETC (Environmental Testing Chamber) Viewer is as an option that can be used with the rheometer for
the following purposes:
• Viewing the edge of plates and cones and the torsion sample
• Providing streaming video on Status page and during tests
• Capturing images with data point (not fast sampling)
• Viewing point image in TRIOS Instrument Control Software
The software provided with the ETC Viewer works with any USB camera so a web cam can be easily used
for Peltier tests. The viewer assembly is air cooled to allow it to perform over whole temperature range of
the ETC (-160 to 600°C). The primary and secondary illumination, as well as the focusing aspects of the
viewer, are all controlled from Rheology Advantage Instrument Control software for your convenience.
The UV Curing Accessory
UV-curable materials are widely used for coatings, adhesives, and inks. When these materials are exposed
to UV radiation, a fast cross-linking reaction occurs, typically within less than a second to a few min-
utes.Two SmartSwap™ accessories for rheological characterization of these materials are available for the
AR-G2 and AR 2000ex rheometers. Onc accessory uses a light guide and reflecting mirror assembly to
transfer UV radiation from a high-pressure mercury light source. The second accessory uses self-contained
light emitting diodes, LEd, arrays to deliver light to the sample. Accessories include 20 mm quartz plate,
UV light shield, and nitrogen purge cover. Optional temperature control to a maximum of 150°C is avail-
able using AR Series Electrically Heated Plates (EHP) option. disposable plates are available for hard UV
coatings which cannot be removed from the plates once cured.
Refer to the UV Curing
Accessories Getting Started Guide for additional information.

WARNING: After ETC use, do not turn off the cooling air to the ETC Viewer
until the unit has returned to room temperature. Doing so could damage the
lens assembly and/or camera chip.
