RTCt

Reference Temperature Calibrator

  • up to 6 preset temperatures for faster calibration across frequent tasks

  • With a graphical display for stability and DLC monitoring, the RTCt offers real-time insights at a glance, adding visual clarity to the numerical displays of the RTC.

  • Tailor the interface and name your calibration settings for easy access

  • Expanded range down to -35°C, ideal for extreme applications.

  • Up to 5 automated temperature switch runs, versus the single run available in the previous model.

  • Includes rate control in all modes, ensuring precise temperature adjustments.
