AM Trace is a transportable oxygen and moisture analyser designed to measure the internal atmosphere in the build chamber of an Additive Manufacturing Machine. AM Trace has a measurement range of 1ppm to 25% oxygen. This sensor is unaffected by hydrocarbons or volatile atmospheres and is specifically designed for low Oxygen measurement (<100 PPM) on Additive Manufacturing Machines. The AM Trace has a fast response time from 20.9% to low PPM Oxygen. AM Trace also incorporates a moisture sensor which allows measurement of moisture in the range of -60°C to +60°C. With touchscreen technology and front facing inputs / outputs this analyzer can be integrated into any system with ease.
