PTCt Series – Professional Dry Block Temperature Calibrators

PTCt Series Dry Block Temperature Calibrator
PTCt Series Dry Block Temperature Calibrators

Reliable industrial temperature calibration with improved usability and workflow efficiency

The PTCt Series builds on the proven PTC dry‑block temperature calibrator platform and introduces improved usability, enhanced calibration visibility, and extended functionality.

The instruments provide stable and accurate temperature control for calibration of RTDs, thermocouples, transmitters, and temperature switches in both industrial and laboratory environments.

With an updated user interface and improved workflow support, the PTCt Series enables efficient, repeatable, and well‑documented calibration tasks.

Key features

  • Touchscreen user interface with configurable screen views
  • Graphical calibration display and remote access (Option RG – Remote & Graph)
  • Automated calibration functions including Auto Step and switch test
  • Dual sensor‑under‑test capability for parallel calibration (model B)
  • Integrated connectivity for data transfer, remote access, and documentation

Improved usability for calibration workflows

The PTCt Series improves ease of use compared to traditional temperature calibrators:

  • Touchscreen operation replaces push‑button interface
  • Configurable screen layouts for different calibration tasks
  • Fixed status line with continuous access to calibration data

These features support faster setup, reduced user errors, and efficient operation in field and workshop environments.

Graphical calibration and remote access (Option RG)

Option RG (Remote & Graph) enhances both visibility and control of the calibration process:

  • Graphical indication of temperature stability and calibration progress
  • Real‑time visualization of calibration behavior and deviations
  • Remote monitoring and control via web browser over Wi‑Fi or Ethernet

This provides improved insight compared to traditional numeric‑only calibration and supports more flexible workflows.

Automation and multi‑sensor calibration

The PTCt Series supports efficient and repeatable calibration processes:

  • Automated calibration sequences using Auto Step
  • Advanced switch testing with multiple test runs
  • Parallel calibration of two sensors (model B)

These capabilities help reduce calibration time and improve consistency across applications.

Connectivity and documentation

Modern calibration environments require structured data handling and traceability:

  • File export for calibration results
  • Screenshot capture for reporting
  • User‑defined file naming
  • Connectivity via USB, Ethernet, and Wi‑Fi

Remote access functionality enables monitoring and control without being physically present at the calibrator, supporting efficient workflow
