PRODUCT NUMBERS

High-Performance, Fast-Response Thermocouple Probe for R&D and Industrial Testing

The QDC Quick Disconnect Thermocouple Probe with Attached Connector is a versatile, high-quality temperature sensor designed for applications requiring fast, reliable measurements and easy probe interchangeability. Built with a durable mineral-insulated sheath and available with quick disconnect connectors, the QDC probe is ideal for research and development, laboratory testing, and industrial temperature monitoring.

Manufactured in the USA using premium materials and Special Limits of Error (SLE) thermocouple wire, the QDC probe delivers accurate, repeatable temperature measurements while offering the flexibility to quickly connect and disconnect sensors as needed.

Designed for Fast, Flexible Temperature Measurement

The QDC thermocouple probe is engineered for applications where sensors must be frequently changed, repositioned, or replaced without rewiring the system. The integrated quick disconnect connector allows users to easily swap probes, reducing downtime and simplifying testing procedures.

This makes the QDC ideal for:

  • Research and development environments

  • Laboratory testing and validation

  • Prototype evaluation

  • Multi-point temperature measurement setups

  • Industrial troubleshooting and diagnostics

The ability to quickly disconnect and reconnect sensors improves workflow efficiency and enables more flexible testing configurations.

Quick Disconnect Connector for Easy Integration

Each QDC thermocouple probe is supplied with a built-in connector, available in both miniature and standard configurations:

  • Miniature 2-pin connector

  • Standard 2-pin connector

  • Male plug or female jack options

This design allows for rapid connection to thermocouple extension wire, instrumentation, or data acquisition systems, eliminating the need for hardwired connections and simplifying installation.

Mineral Insulated Sheath for Strength and Flexibility

The QDC probe features a mineral insulated (MI) sheath, providing an excellent combination of durability and flexibility.

  • Sheath insulation: Magnesium oxide (MgO)

  • High mechanical strength

  • Bendable for routing in tight spaces

  • Resistant to vibration and mechanical stress

This construction ensures long-term reliability, even in demanding environments.

Wide Range of Thermocouple Types

The QDC thermocouple probe is available in multiple thermocouple types to suit different applications:

  • Type E

  • Type J

  • Type K

  • Type T

Each thermocouple type offers unique characteristics in terms of temperature range and sensitivity, allowing users to select the optimal configuration for their specific application.

Broad Operating Temperature Range

The QDC probe supports a wide range of operating temperatures depending on the thermocouple type:

  • Type E: –328°F to 1600°F

  • Type J: 32°F to 1400°F

  • Type K: –328°F to 2300°F

  • Type T: –328°F to 700°F

This versatility makes the probe suitable for both low-temperature and high-temperature measurement applications.

Special Limits of Error Accuracy

The QDC thermocouple probe is manufactured using Special Limits of Error materials, providing enhanced measurement accuracy:

  • Accuracy: Greater of ±0.4% of reading or ±1.1°C

This ensures reliable and repeatable data, making the probe suitable for precision testing and critical applications.
