• High accuracy: RTC-156/157 – Up to ±0.04°C using the external reference sensorRTC-700 – Up to ±0.11°C using the external reference sensor 4-wire True-Ohm-Measurement technology is used
• Excellent stability: RTC-156/157 – 0.005°C,  RTC-700 – 0.008°C
• Wide temperature range: RTC-156: -30 to 155°C (-22 to 311°F) Dry-blockRTC-157: -45 to 155°C (-49 to 311°F) Dry-blockRTC-700: 33 to 700°C (91 to 1292°F) Dry-block
• Improved temperature homogeneity: Unique active dual-zone (RTC-156/157) or triple-zone (RTC-700) block ensures good temperature homogeneity in the calibration zone.
• DLC – Dynamic Load Compensation: PATENT PENDING!Perfect temperature uniformity in the insert, even when calibrating large sensors or many sensors at a time. B and C models only.
• Display indicator for temperature uniformity: Shows the degree of temperature uniformity in the insert when using the new DLC technology. B and C models only.
• Intelligent reference sensors: JOFRA reference sensors are supplied with intelligent plugs, holding the calibration data (coefficients) of the reference sensor.
• USB communication: All RTC calibrators communicate via an USB port.
• Time-saving High speed heating and cooling times.
• EURAMET: Best performing dry-block with regard to the EURAMET/cg-13/v.01 guideline for testing of dry-blocks.
