Thermo Scientific
Congratulations on your purchase of a Thermo Scientific Thermolyne NCAT Asphalt Content Tester.
Introduction
The unit is designed to perform a specific test within your laboratory. Please read the instructions
carefully to ensure that you receive maximum benefit from it. Also, be sure to fill out and return the
enclosed warranty registration card. We would like to receive the information requested, and it will
help us assure you of proper warranty coverage.
Intended Use
The NCAT Asphalt Content Tester is an analyzer which determines the asphalt content of a sample by
loss on ignition per standard methods. The asphalt sample is bathed in oxygenated air and weighed
continuously throughout the ignition procedure. The NCAT Asphalt Content Tester’s software
identifies the endpoint of ignition and indicates the completion of the test. Results are documented by
a printer.
General Usage
Do not use this product for anything other than its intended usage.
Software Updates
Software improvements are initiated based on market feedback. Currently your tester contains Revision
H software. You will be notified by your sales representative, distributor or the manufacturer as a
software improvement becomes available. A software packet includes installation instructions,
operational data and an EPROM. The EPROM is easy to install and can be installed within a few
minutes.
Theory of Operation
The furnace is heated to a setpoint temperature within the range of 450° - 550°C. The hot mix asphalt
sample is weighed, equally divided and placed in two screened baskets which are mounted on a tray
assembly. This complete assembly is placed on the furnace hearth tray. The hearth tray is mounted on
four ceramic support tubes, which are in turn mounted on a digital balance platform. A blower draws
ambient air through the four ceramic tube support openings located on the chamber floor. This
oxygenated air saturates the spread asphalt sample to promote ignition and ashing. The released
volatiles are further oxidized while passing through a ceramic filter heated to 750°C in a chamber above
the main chamber. Five air exit ports direct the exhausted air to a louvered plenum. The exhaust is then
cooled by mixing with ambient air. The blower then directs the exhaust through the plenum exhaust
port. Standard seamless exhaust tubing directs the exhaust to an outside exhaust system.
