Introducing the RTCt‑159: Ultra‑Cool Precision Meets Next‑Generation Usability

AMETEK STC is proud to introduce the RTCt‑159, a groundbreaking reference temperature calibrator engineered for applications where deep‑cold capability, high stability, and intuitive workflows are essential. With extreme cooling down to –100°C and advanced temperature control technologies, the RTCt‑159 sets a new benchmark for dry‑block calibration performance.
Designed for industries where compliance, accuracy, and efficiency are critical—including pharmaceuticals, food & beverage, aerospace, automotive, and power generation—the RTCt‑159 delivers the precision and versatility needed for both laboratory and field environments.

A Leap Forward in User Experience

At the heart of the RTCt‑159 is its all‑new touchscreen interface, developed to make calibration workflows faster, safer, and more intuitive.
  • A clear, real‑time display shows progress, live stability, and setpoints at a glance.
  • The adaptive graph automatically zooms for micro‑deviation visibility once stability is reached, enabling unprecedented calibration insight.
  • Active inputs are highlighted in green, with unavailable options greyed out—minimizing user errors during setup.
With quick access to Calibration, Auto Calibration, Auto Step, and Switch Test, the interface puts advanced functionality right at the user’s fingertips.

Extreme Cooling, Exceptional Stability

The RTCt‑159 combines ultra‑cool performance with advanced thermal control technologies to ensure consistent and repeatable calibrations.
  • Temperature range from –100°C to +155°C
  • Dual‑zone heating for uniform temperature distribution across the insert
  • Dynamic Load Compensation (DLC), providing real‑time correction for load‑induced thermal variations
These features work together to maintain a highly homogeneous calibration environment—essential when calibrating multiple sensors or larger probes where even minor gradients can affect results.

Wireless Connectivity for Modern Workflows

With integrated Wi‑Fi connectivity, the RTCt‑159 enables technicians to:
  • Monitor calibrations remotely
  • View live data through a web browser
  • Adjust settings and review progress without standing beside the instrument
This streamlines workflows in cleanrooms, production areas, and test labs where mobility and efficiency matter.


Simultaneous Two‑Sensor Calibration

The RTCt‑159 features two sensor‑under‑test (SUT) inputs, allowing users to calibrate multiple sensors at once—significantly increasing throughput for high‑volume operations.
Combined with its ultra‑fast cooling and heating performance, the RTCt‑159 helps reduce downtime and supports highly efficient calibration routines.

Intelligent Reference Sensors for True Plug‑and‑Play Accuracy

Supporting JOFRA STS intelligent reference sensors, the RTCt‑159 eliminates manual entry of calibration coefficients and reduces the risk of operator error. Each sensor stores:
  • Calibration coefficients
  • Serial number
  • Calibration date
This ensures complete traceability and immediate readiness during setup—simply plug in the sensor and begin.

Flexible, Automated Workflows

The RTCt‑159 is designed for technicians working with complex or repetitive routines.
Key automation features include:
  • Auto Step: program up to 20 temperature steps with custom hold times
  • Switch Test: automatic open/close/hysteresis detection for temperature switches
  • Instant documentation via screenshot for audits or certificate generation
These functions significantly reduce manual work and ensure consistent, repeatable results across all calibration cycles.

Engineered for Demanding Industries

The RTCt‑159 is a powerful solution for environments requiring high accuracy, full traceability, and strict regulatory compliance, including:
  • Pharmaceutical cold‑chain equipment
  • Aerospace test components
  • Food safety thermal systems
  • Automotive testing and battery development
  • Energy and power generation instrumentation

Its robust construction and high accuracy make it equally at home in on‑site production environments and accredited calibration laboratories.

A Modern Calibration Experience

From its intuitive touchscreen to its ultra‑cool thermal range, from DLC homogeneity control to dual‑sensor capability, the RTCt‑159 brings together the best of modern technology in a single, easy‑to‑use instrument.
It represents the next step forward in AMETEK STC’s commitment to delivering calibration tools that improve workflow efficiency, strengthen compliance, and give users the confidence to trust every measurement.
