This bench top system from Surface Measurement Systems uses an integrated quartz microbalance to track mass changes during controlled humidity steps. An automated vapor generator with precision mass flow controllers provides a programmable humidity range of 0 to 95 percent, while a temperature-controlled enclosure holds samples at ambient to 60 °C. Up to eight samples can be mounted on microbalance arms for sorption isotherm and kinetics studies. Dedicated software logs real-time data for moisture uptake in polymers, pharmaceuticals, powders and films. Ideal for material characterization in research and quality control.
