RTCt-159 Reference Temperature Calibrator, -100°C to 155°C

The RTCt-159 is the ultra cooler of the line: -100°C to 155°C from a single dual-zone dry-block, merging extreme cooling with ultra-stable performance and speed for cold-chain, aerospace, and laboratory reference work that previously needed a bath.

The RTCt series is JOFRA's next-generation reference dry-block platform: a touchscreen interface with graphical stability visualization, dual sensor-under-test channels, Dynamic Load Compensation (DLC) with enhanced visuals, Auto Step and switch-test functions, work-order automation with JofraCal, Wi-Fi and Ethernet connectivity for remote monitoring, and file output of results and screenshots. It keeps the accessories and inserts of the RTC line it replaces, so existing tooling carries over.

Build it your way: the Configure tab walks through the model version (A basic, B full with all inputs, C middle), power, insert, DLC and reference-sensor options, ISO 17025 accredited certificate choices, and carrying case, with list pricing from AMETEK's 2026 USD price list. Quote-first: the configured part number comes to Valley for confirmation before anything is ordered.
