Overview
The United Electric 650 chart recorder is a mechanical strip-chart instrument designed for continuous temperature data acquisition and logging. The UE 650, including the MK-6464 T650-M002C-14BS configuration, has been a standard in industrial facilities for decades due to its simplicity, reliability, and ease of installation. This circular-chart recorder captures temperature trends on replaceable paper charts, providing a permanent record of facility conditions without requiring electrical connectivity to a control system or computer network.
Key Features
- Circular 24-hour or continuous chart design for uninterrupted temperature logging
- Direct mechanical operation—no software or calibration settings required
- Thermal pen or ink-jet marking mechanism for clear, permanent data recording
- Wall-mounted compact frame fitting standard electrical enclosure cutouts
- Wide temperature range coverage (typically 50°F to 650°F depending on probe configuration)
- Compatible with standard thermocouple or resistance temperature detector (RTD) inputs
