Overview
The Honeywell R7352 is a remote temperature control device with an extended temperature range of 0–1400°C (0–2500°F). As part of Honeywell’s legacy remote temperature controller line, this unit is suitable for industrial and commercial process control applications where temperature sensing must be located remotely from the control station. This used unit has been inspected and is fully operational.
Key Features
- Temperature range: 0–1400°C (0–2500°F)
- Remote sensor capability for applications requiring sensing outside control area
- Manual and automatic control modes
- Suitable for air, liquid, and steam temperature regulation
- Compact design for panel or wall mounting
- Durable electromechanical construction proven in industrial environments
