4730/31 New Technology Oven (NTO)

Troxler now offers advanced Infrared (IR) technology to measure asphalt content by the NCAT ignition method. The H.M.A. sample is ignited using IR elements. This produces a very clean and efficient burning of the asphalt while limiting the aggregate degradation. The NTO combines this sophisticated oven with an integrated weighing system to continuously measure the bituminous weight loss during combustion and to automatically display the percent of asphalt in the mix. The remaining aggregate can be sieved for gradation analysis.

How It Operates
The Troxler Asphalt Ignition oven is very easy to use. The asphalt mixture is spread on mesh sample baskets and the basket assemblies are placed in the NTO chamber. Simply close the oven door and press the start key to begin the combustion process. Built-in scales automatically measure mass loss and percent loss. A built-in printer provides a constant record of the results. The NTO stores up to 300 test results and correction factors. Either positive or negative aggregate correction factors can be used for a specific mixture. Data stored in the console can be downloaded by a computer through the RS-232 serial interface.
