Which Traditional Devices Can the PR235 Replace? A Complete Upgrade Path
Source: | Author:L | Published time: 2025-08-22 | 4 Views | Share:

1. Traditional Devices Commonly Used in Calibration

Historically, engineers and technicians carried several different instruments for calibration tasks, including:

  • Dry-Block Furnaces: For temperature generation and sensor calibration.

  • Multifunction Signal Calibrators: For current, voltage, resistance, and frequency checks.

  • Reference Thermometers: For precise temperature comparison.

  • Paper-Based Logging Systems: For manual data recording and reporting.

While effective, using multiple devices can lead to higher costs, slower workflows, and more frequent errors.

2. How PR235 Consolidates These Functions

✅ Dry-Block Furnace Replacement

The PR235 integrates a high-accuracy dry-block furnace, offering stable and uniform temperature control for sensor calibration in the field or lab.

✅ Signal Source & Measurement Device

It functions as a multifunction calibrator, capable of sourcing and measuring current, voltage, RTDs, thermocouples, and resistance, eliminating the need for separate electrical calibrators.

✅ Built-in Reference Sensor

With an internal reference channel, PR235 removes the need for carrying additional reference thermometers.

✅ Digital Data Logging & Reporting

Automatic data storage and USB export make manual logbooks obsolete, saving time and reducing errors during audits.

3. Benefits of Upgrading to PR235

  • Portability: One device instead of carrying 3–4 separate instruments.

  • Efficiency: Reduce calibration time by up to 40% through multi-point and automated recording.

  • Compliance: Built-in traceability supports ISO/IEC 17025 requirements.

  • Cost Savings: Lower equipment investment and maintenance expenses.

4. Typical Upgrade Path for Users

  • Step 1: Replace standalone dry-blocks with PR235’s integrated furnace.

  • Step 2: Transition from multifunction calibrators to PR235’s built-in sourcing/measurement features.

  • Step 3: Eliminate paper logs with PR235’s digital storage and reporting.

  • Step 4: Standardize calibration across teams with one device platform.

Conclusion

The PR235 can effectively replace traditional dry-block furnaces, signal calibrators, reference thermometers, and manual logging systems. By integrating these functions, it offers a practical upgrade path for companies seeking efficiency, accuracy, and compliance in calibration processes.

For industries moving toward smart manufacturing, adopting the PR235 is not just an equipment change—it’s a strategic step toward modernized, streamlined calibration.
