The Omega CT585 is a microprocessor-based temperature and pressure recorder that combines real-time digital display with continuous circular chart documentation. This self-contained unit captures dual-parameter data on 200 mm (8″) charts with user-selectable recording intervals of 1, 7, or 32 days, storing peak values for both channels. Front panel controls enable easy selection of display units (psig, °C, or °F) and programming functions, while an integral beeper and relay contact provide alarm notification capabilities.
