  • Accuracy: High accuracy down to ±0.04°C using external reference sensors.
  • Stability: Excellent stability of 0.01°C.
  • Temperature Range: RTC-158 operates from -22 to 155°C, and RTC-250 from 28 to 250°C.
  • Homogeneity: Active dual-zone block ensures good temperature homogeneity.
  • Dynamic Load Compensation (DLC): Ensures temperature uniformity, available in B and C models.
  • Intelligent Sensors: Plug’n’play calibration system with intelligent reference sensors.
  • Communication: USB port for easy communication.
Features:

Additional Features:
  • MVI: Mains power Variance Immunity for stable operation in fluctuating power conditions.
  • Auto-Stepping: Programmable temperature steps with results display.
  • Work Orders: Allows stand-alone operation and prevents unauthorized changes.
Hardware and Software Requirements:
  • PC Requirements: Minimum hardware includes Intel Pentium II 1.4 GHz processor, 128MB RAM, and USB port. Software requires Microsoft Windows ME, XP, or 7.
JOFRACAL Software: This versatile software supports calibration of various temperature and pressure sensors, integrating seamlessly with JOFRA instruments. It allows for manual data entry and storage for later analysis.
DLC System: The Dynamic Load Compensation (DLC) system enhances calibration accuracy by maintaining temperature homogeneity, even with varying sensor loads. It allows for simultaneous calibration of multiple sensors and compensates for sensor production tolerances.
Input Specifications: The calibrators support a range of input types, including RTD and thermocouple inputs, with specific accuracy levels detailed for each type.
Physical and Operational Details: The document outlines the physical dimensions, weight, power consumption, and environmental operating conditions for the RTC-158/250 models.
Accessories: Various inserts and a liquid bath kit are available for different calibration needs, with specific part numbers provided for ordering.
Model Variants: Three models are available: Model A (basic), Model B (full with DLC and reference sensor inputs), and Model C (middle with DLC and reference sensor inputs). All models feature dual-zone heating/cooling, USB communication, and programmable temperature settings.
Ordering Information: The RTC-158 series operates from -22 to 155°C, while the RTC-250 series operates from 28 to 250°C. Power supply options vary by region, and insert types include undrilled and multi-hole options. Calibration certificates are available in various forms, including traceable and accredited options.
AMETEK Overview: AMETEK offers a range of test and calibration instruments under various brands, including JOFRA for temperature calibrators, M&G for pressure testers, and Chatillon for force measurement. The company provides global support with contact information for offices in the UK, France, Germany, Denmark, USA, India, Singapore, and China.

Perfect temperature uniformity in the pendin Liquid Bath insert, even when calibrating large sensors or many sensors at a time. B and C models only » Temperature uniformity indicator Shows the degree of temperature uniformity in the insert when using the new DLC technology. B and C models only In combination with the stirrer the newly developed sensor basket ensures virtually zero axial and radial gradients in the calibration zone » Intelligent reference sensors JOFRA reference sensors are supplied with intelligent plugs, holding the calibration data (coefficients) of the reference sensor. This is a truly plug’n’play calibration system AMETEK continues to develop new techniques to improve performance, accuracy, convenience and functionality of the well-known JOFRA calibration products. By doing so, we maintain our position as the leading worldwide manufacturer of temperature dry-block calibrators. Advantages of the combined liquid bath/dry-block calibrator Calibration of many sensors at a time due to more space for example in connection with validation of many thermocouples, which saves time • Automatic calibration of as many as 24 sensors at a time For customers, who only want to use liquid baths For calibration of odd sizes and shapes of sensors including sanitary sensors WET = no need for inserts, that fit the sensors DRY = more space for calibration of special sensors Industries who need to calibrate many sensors at a time or short sensors can benefit from the big well JOFRACAL software and RTC B-models can handle on-line calibration and documentation of multiple sensors calibrated simultaneously All RTC calibrators communicate via an easy-to-use USB port Best performing dry-block with regard to the EURAMET/cg-13/v.01 guideline for testing of dry-blocks ISO 9001 Manufacturer Specification Sheet, SS-RTC-158/250

Unique temperature performance The RTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dualzone heating technology. The RTC-series features our well-known active dual-zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation throughout the entire calibration zone. The upper zone compensates for heat loss from...
