Agilent/Keysight 34307A

The Keysight 34307A is a J-type thermocouple kit that expands temperature measurement capabilities across Keysight data acquisition systems and compatible digital multimeters. The kit contains ten unterminated thermocouples, each 180 cm in length with 20-gauge wire and Teflon jacketing, rated for temperatures from -40°C to +750°C with a sensitivity of approximately 50 µV/°C.

– Key Features

Each thermocouple delivers nominal sensitivity of 50 µV/°C across an extended temperature span suitable for laboratory and industrial test environments. The Teflon jacket provides chemical resistance and mechanical protection. Extended 72-inch leads enable flexible probe placement in diverse measurement scenarios. Unterminated design allows integration with multiple connector standards and measurement platforms.

– Typical Applications

Laboratory temperature monitoring and characterization. Industrial process temperature measurement and control verification. Multi-point thermal profiling in test chambers and ovens. Comparative temperature assessment in thermal cycling applications.

– Compatibility & Integration

Direct Integration
• Keysight 34970A Data Acquisition/Switch Unit
• Keysight 34972A Data Acquisition/Switch Unit

Secondary Compatibility (with external program and reference junction)
• Keysight 34401A Digital Multimeter
• Keysight 34460A Digital Multimeter
• Keysight 34461A Digital Multimeter

When deployed with 34970A or 34972A units, the thermocouples integrate directly into the DAQ system’s temperature measurement pathway. For use with 34401A, 34460A, or 34461A DMMs, an external program converts measured voltage output to temperature readings. Accurate reference junction—either ice bath or electronic reference—is required for precision measurements when using DMM-based configurations.
