Lake Shore 211 Cryogenic Temperature Monitor

Description

The Lake Shore Model 211 Cryogenic Temperature Monitor is a compact, single-channel instrument designed for precise temperature measurements in cryogenic environments. It supports both diode and resistance temperature detector (RTD) sensors, making it suitable for applications such as liquefied gas storage, cryopump control, cryo-coolers, and materials science experiments.​

Key Features:

• Wide Temperature Range: Measures temperatures from 1.4 K to 800 K, depending on the sensor used.

• Sensor Compatibility: Supports silicon diodes, GaAlAs diodes, platinum RTDs, and Cernox™ sensors.

• High Accuracy and Resolution: Utilizes 4-lead differential measurement and 24-bit analog-to-digital conversion for high accuracy and 5-digit measurement resolution.

• Analog Output: User-configurable analog output options include 0 to 10 V or 4 to 20 mA, facilitating integration with various systems.

• Digital Interface: Equipped with an RS-232C serial interface for remote operation and data retrieval.

• Alarm and Relay Functions: Features high and low alarms that can operate in latching or non-latching modes, along with relay outputs for control applications.

• Display: Large 5-digit LED display provides clear temperature readings.

• Data Logging: Temperature data can be read up to seven times per second via the computer interface, with the display updating twice per second.
