Overview
This document provides detailed information about Hart's temperature calibration baths, which are designed to reach extremely low temperatures without the need for external coolants. These baths offer superior stability and uniformity, making them ideal for high-performance calibration needs.

Specifications
The baths are available in three models, each with different temperature ranges:

• 7060: –60 °C to 110 °C
• 7080: –80 °C to 110 °C
• 7100: –100 °C to 110 °C

Stability and uniformity are key features, with the 7100 model offering stability of ± 0.008 °C at –100 °C. The baths are self-contained, requiring no auxiliary cooling fluids.

Features

• Self-contained refrigeration system
• Large working areas for increased throughput
• Digital display with push-button data entry
• Automation options available with Interface-it software

Automation and Software
Each bath can be automated using Hart's 9930 Interface-it software, allowing for complete automation of the calibration process. An additional IEEE-488 interface can be added for enhanced connectivity.

Testing and Calibration
Periodic testing of the baths is recommended to ensure continued performance. Tests should focus on bath instability and non-uniformity, which directly affect calibration uncertainties. These tests should be conducted over the specific calibration zone used in your process.

Ordering Information
Various accessories and automation packages are available for each bath model, including fluid level adapters and access covers. The document provides specific ordering codes for each item.

Conclusion
Hart's baths are designed for precision and reliability, with a guarantee of performance. They are suitable for users requiring high stability and uniformity in temperature calibration processes.
