The M300 data acquisition and datalogging system from Rigol Technologies integrates the company’s 6.5-digit multimeter technology into a versatile system mainframe with modules enabling applications from multichannel scanning to switching and control. The M300 mainframe can hold up to five modules and up to 320 switch points, and the graphical display improves scan configuration, monitoring, and storage over traditional front panel interfaces. The module’s flexibility enables a mix of thermocouples, resistance temperature detectors, and thermistors to maximize accuracy and throughput of temperature scans. Terminal blocks contain cold junction compensation references to improve temperature reading accuracy. Once configured, users can monitor trend graphs of critical channels on the display, can set up multiple alarms, and can store data on an attached USB memory stick. UltraAcquire Software also is included.
