The Honeywell DR45AT-1100-00-000-0-000000-0 (DR4500 Truline) is a microprocessor-based circular chart recorder engineered for continuous process monitoring across industrial sectors including food processing, pharmaceuticals, heat treatment, environmental testing, and water/wastewater treatment. This two-channel model features a Truline pen system that prints chart grids, scales, timestamps, and alphanumeric header data directly onto blank thermal paper, eliminating pre-printed chart inventory requirements and compensating for chart expansion or shrinkage due to humidity variations.
