Astro-Med Dash2MT(DASH II-MT) Two-Channel Field Recorder
The Dash II model MT is the only recorder in the world especially designed for field service. Built for reliable operation under the most demanding physical and environmental conditions, the Dash II is equally at home logging data from oil wells; monitoring operations at steel and paper mills and industrial processing plants; accurately recording data while strapped onto bouncing army tanks; monitoring nuclear power stations; or at work in electric power utilities or troubleshooting telephone lines. Other recorders, with their delicate moving parts or ink writing systems, just can't survive in these applications.
The Dash-2 operates from various power sources: 110/220 VAC, external 11-18 VDC or through built-in rechargeable batteries lasting up to three hours. Recharge while recording. Just plug the unit into AC line power, and the batteries recharge as the recorder runs.
