The Lake Shore DRC-82C is a microprocessor-based cryogenic temperature controller designed for precise thermal regulation across 1.4 K to 330 K. This rack-mountable instrument delivers true analog control via closed-loop feedback, enabling stable operation in advanced research and industrial cryogenic applications requiring exacting temperature stability.
## Technical Specifications
• **Operating Temperature Range:** 1.4 K to 330 K
• **Control Architecture:** Microprocessor-based with true analog control output
• **Sensor Input Resolution:** Diode sensor voltages digitized to 100 microvolts; full scale dependent on input card configuration
• **Temperature Display Resolution:** Up to 5 digits in Kelvin (K), Celsius (°C), Fahrenheit (°F), or sensor units (volts, ohms, or nanofarads)
• **Gain Parameter:** Defines maximum allowable error signal before full output power is produced; plotted against deviation signal across variable amplifier gains (e.g., Av = 100, Av = 1000)
## Key Features
