The Astro-Med Dash 18 field chart recorder is a compact, 18-channel data acquisition recorder ("chart recorder") ideal for medical research applications. The observed waveform data is captured and shown in real-time on a 15.4" color display and stored in memory on an 18 GB hard-drive and optional array recorder.

The Dash 18 is extremely versatile with the capability to capture video and audio data internally. Universal inputs let you connect nearly any signal without using external signal conditioning. The Dash 18 can record a wide range of voltages, temperature, DC Bridge and frequency inputs- all independently set up and enhanced with customizable control buttons.
