This unit
The Lake Shore DRC-93CA is a microprocessor-based temperature controller engineered for precise cryogenic temperature management. It delivers real-time analog control using three-term (PID) circuitry to maintain user-defined setpoints with high stability and accuracy. The controller supports internal programming with up to 99 steps and accommodates multiple sensor types, making it adaptable to diverse low-temperature applications.
