Profile: Instrument Specialists, Inc provides products for thermal analysis. The iSeries STA (Simultaneous Thermal Analyzer) features 0.1 microgram balance resolution, advanced control algorithms with cutting edge design. Our sensitive heat flux plate provides reproducible heat flow data along with simultaneous weight measurement during the entire experiment. The instrument is ideally suited for evolved gas analysis with its low purge gas flow and sample environment. Data collection interface system allows for acquisition and coordination of thermal experiments from many thermal analyzers. The system replaces the existing computer and interface with a DCI and the windows software. It has three channels of high resolution analog inputs. These inputs connect to the existing analyzer to collect temperature and Y axis signals. It also has three relays which provides remote instrument heat, hold and cool activation controlled by the software. It has one relay to operate gas switching devices so gases can be changed during the thermal experiment.
