Chart recorders can track trends in real time while others retain electronic and hard copy data for future analysis. A chart recorder can be circular, flatbed, XY, or hygrothermagraph. The type of information recorded is determined by what you need such as temperature, relative humidity, pressure, voltage, and water level. If your application requires real time viewing and electronic storage of trend data, we have a comprehensive selection of paperless recorders and data acquisition instruments. Paper, pens, and mounting hardware are also available.
