The Honeywell DR450T-1100-00-001-0-E-0111 is a 12-inch circular chart recorder engineered for industrial process documentation and control. This single-pen, 24-hour rotation instrument prints its own chart on thermal-sensitive paper, eliminating pre-printed inventory requirements and delivering consistent accuracy independent of ambient temperature and humidity. The microprocessor-based design offers field configurability via keyboard with English-language prompts, housed in a NEMA 4X enclosure for demanding plant and factory environments.
