Omega CT485B Temperature & Humidity Portable Chart Recorder

The Omega CT485B is a portable, micro-based circular chart recorder designed for precise monitoring of temperature and relative humidity in industrial, laboratory, and environmental applications. This versatile device features auto-ranging capabilities, allowing it to automatically select the appropriate scale for temperature (in °C or °F) and humidity (%RH) measurements. It includes user-settable high and low alarms with relay contacts for external notifications, making it ideal for process control, quality assurance, and data logging in HVAC systems, cleanrooms, or storage facilities. Key benefits include its compact, battery-powered portability for field use, digital display for real-time readings, and compatibility with standard 4-inch circular charts for easy data visualization and archiving. Compared to digital data loggers, the CT485B offers tangible, hard-copy records that are advantageous in regulated environments requiring non-editable documentation. However, it may lack the storage capacity and connectivity of modern USB-enabled loggers, and its analog charting can be less precise for high-resolution needs. The unit supports various chart speeds and types, with built-in sensors or external probes for flexibility. Overall, it's a reliable, cost-effective solution for applications demanding continuous, visual monitoring without complex software integration.
