The Parr 4848 Series Digital Temperature Regulator represents a significant advancement in process control for laboratory reactors and pressure vessels. Designed to offer maximum flexibility and precision, the 4848 series integrates core thermal management with an expandable, modular architecture that adapts to a wide variety of scientific research requirements.

Modular and Expandable Architecture

At the heart of the 4848 Series is its unique modular chassis. While the primary slot is dedicated to a high-precision PID temperature control module, the system features three additional expansion slots. These slots can be populated with optional "plug-in" modules, including Pressure Display Modules (PDM) for reactor pressure monitoring, Stirrer Motor Speed Control Modules (MCM), and High-Temperature Limit Modules (HTM) for enhanced laboratory safety.

Advanced Process Control and Connectivity

The controller utilizes a sophisticated PID algorithm with autotune functionality, ensuring rapid setpoint attainment and minimal overshoot, even in vessels with significant thermal lag. A key standard feature is the built-in USB port, which, when used with Parr’s dedicated software, allows for real-time data acquisition and remote monitoring. This digital connectivity is essential for modern labs requiring meticulous documentation of experimental thermal profiles.

Designed for Laboratory Safety

• Over-temperature Protection: Optional modules provide independent mechanical or digital cutoffs for critical safety applications.
• User-Friendly Interface: Large digital displays show actual values (PV) and setpoints (SV) clearly, with intuitive tactile controls for field adjustments.
• Robust Construction: Built to withstand the rigorous environment of chemical and petrochemical research, ensuring long-term operational reliability.

Typical Applications

• High-pressure chemical synthesis and catalytic reactions
• Petroleum and fuel additive testing in stirred reactors
• Polymerization studies requiring precise ramp and soak control
• Materials research in controlled atmosphere pressure vessels
