Jofra PTCt-155 extends the proven PTC dry-block temperature calibrator platform with enhanced usability, clearer calibration visibility, and expanded functionality. It delivers stable and accurate temperature control for calibrating RTDs, thermocouples, transmitters, and temperature switches in industrial and laboratory environments.
\nThe updated interface and workflow features support efficient, repeatable, and well-documented calibration tasks.<\/p>\n
Key features<\/b>
\n– Touchscreen interface with configurable screen views
\n– Graphical calibration display and remote access with Option RG (Remote & Graph)
\n– Automated calibration using Auto Step and switch test functions
\n– Parallel calibration of two sensors with model B
\n– USB, Ethernet, and Wi-Fi connectivity for data transfer, remote access, and documentation<\/p>\n
Improved calibration workflow<\/b>
\nTouchscreen operation replaces the traditional push-button interface, while configurable screen layouts allow users to adapt the display to different calibration tasks. A fixed status line keeps calibration data continuously accessible.
\nThese features help speed setup, reduce user errors, and support efficient operation in field and workshop environments.<\/p>\n
Graphical calibration and remote access<\/b>
\nOption RG (Remote & Graph) improves visibility and control throughout the calibration process.
\n– Graphical indication of temperature stability and calibration progress
\n– Real-time visualization of calibration behavior and deviations
\n– Remote monitoring and control through a web browser using Wi-Fi or Ethernet
\nThe graphical approach provides more insight than numeric-only calibration and enables more flexible workflows.<\/p>\n
Automation and multi-sensor calibration<\/b>
\nJofra PTCt-155 supports repeatable calibration with automated Auto Step sequences and advanced switch testing with multiple test runs. Model B enables two sensors to be calibrated in parallel, helping reduce calibration time and improve consistency across applications.<\/p>\n
Connectivity and calibration documentation<\/b>
\nJofra PTCt-155 Series supports structured data handling and traceability through:
\n– File export for calibration results
\n– Screenshot capture for reports
\n– User-defined file naming
\n– USB and Ethernet connectivity
\nRemote access allows monitoring and control without being physically present at the calibrator, supporting efficient calibration workflows and documentation.<\/p>\nTechnical Information:<\/h3>\n
