Overview
The RTCt-157 covers −45 to 155°C (−49 to 311°F) as a dual-zone dry block with DLC. The RTCt Series delivers advanced dry-block calibration performance for professionals who need high stability and a streamlined user experience from deep-cold through elevated temperatures. A shared platform across the series provides consistent operation, an intuitive touchscreen with real-time adaptive graphing, and Wi-Fi for browser-based monitoring and control. Patented Dynamic Load Compensation (DLC) monitors and compensates for thermal differences caused by sensor mass or multiple probes. Most models allow simultaneous calibration of two sensors. Flexible workflows include Auto Step (up to 20 programmable steps), switch testing with automatic open/close/hysteresis capture on Model B, and a built-in screenshot for documentation. JofraCal software automates sensor calibration routines and certificate generation.
