RTC-159 - Ultra Cooler - 1

Reference Temperature Calibrator RTC-159 Ultra Cooler » Widest temperature range From -100 to 155°C (-148 to 311°F) » High accuracy Down to ±0.06°C (±0.11°F) using the external reference sensor. 4-wire True-OhmMeasurement technology is used » Most stable ultra cooler calibration on the market » Perfect temperature Even when calibrating large sensors or many sensors at once, the unique, patent pending, dynamic load compensation (DLC) system in combination with JOFRA´s active dual-zone technology ensures perfect temperature homogeneity. (B and C models only) ed Patent y hnolog ng tec cooli » Fastest calibration possible The efficient free piston stirling cooler (FPSC) technology is used to secure fast cooling and heating temperature changes Weighing only 15.2 kg (33.5 lb), the RTC-159 is by far the lightest and most portable ultra cooler on the market » Intelligent reference sensor communication JOFRA reference sensors are supplied with intelligent plugs, holding the calibration data (coefficients) of the reference sensor. This is a truly plug & play calibration system All RTC calibrators communicate via an easy-to-use USB port Best performing dry-block with regard to the EURAMET/cg-13 guideline for testing of dry blocks ISO 9001 Manufacturer Specification Sheet, SS-RTC-159 The top model dry-block temperature calibrator – the JOFRA® RTC-159, is unsurpassed in the market. It is the most versatile temperature calibrator available with a temperature range that makes it especially ideal for use in the health care, medical, pharmaceutical, biotechnology and food industries. The RTC-159 offers many advantages, such as: • Relevant for many applications With its extremely wide temperature reach, the RTC-159 can be used in many applications where either high heat or extreme cooling is needed • User friendly Intuitive to use and easy to run, the RTC-159 is equipped with a large informative, easy-to-read color display, which makes reading error a thing of the past • Ergonomically correct Lightweight and easy-to-carry, the RTC-159 is easy to move from job to job • Mechanically stable With its high-tech design the RTC-159 ensures durability and lasting quality The RTC-159 is the newest member of the well-known JOFRA RTC family. The RTC family can meet any type of industrial temperature calibration need within the -100 to +700°C (-148 to 1292°F) temperature range.

Standard features Best-in-class temperature homogeneity The RTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format. The JOFRA RTC-series features our well-known active dualzone 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 the sensor-under-test and from the open top....

Enhanced stability The “SET-Follows-TRUE” mode makes the instrument tune in to the temperature reading of the external reference “TRUE” meets the desired “SET” temperature. This feature is important when it is critical that the temperature of the calibration zone matches the desired temperature when measured with accurate external reference sensors. A stability indicator shows when the RTC calibrator has reached the desired temperature and is stable. The user may change the stability criteria for the external reference and the sensor-under-test quickly and simply. The stability criterion is...

Optional features Dynamic Load Compensation (DLC) All RTC calibrators feature active dual-zone temperature control, which improves the homogeneity in the well by adjusting the temperature at the top of the well to the same temperature as at the bottom. The dual-zone keeps the temperature differences to a minimum. To bring the well-documented active dual-zone technology to an even higher level, AMETEK has developed a patentpending, new dynamic load compensation (DLC) system. This system makes it possible to achieve exceptional calibration specifications without being affected by the actual...
