The BK Precision DAS50 4 Channel High Speed Multi-Function Recorder comes suited with 4 analog input channels and the capacity for 32 GB (DAS30/50) internal solid-state memory. The unit is capable for versatile channel configurability, quick sampling (1 MSa/s), an extensive input range (±5 mV to ±500 V) and up to 9.5 hours of battery life. Users can catch transit events in file mode with the 2 µs sampling interval while the expansive memory allows for data to be recorded over extended periods of time.
Each channel is designed to record a different signal like temperature, voltage, current or frequency simultaneously, using a common time base. The easy operation touch screen is built with helpful features like zooming, data scrolling and the ability to drag and drop delta cursors for precision measurements. Built with a CAT III isolation rating, the BK Precision DAS50 is perfect for applications from small sensor signal logging to electrical power analysis.
