Liquid and odd/big size sensor calibration
Two models of the ATC series (ATC-140 and ATC-250) fitted with a 160 mm deep well with a diameter of 63.5 mm (2.5 in) can be used both as dry-block calibrators and as liquid calibration baths with a magnetic stirrer.
A liquid bath and a dry-block diameter of 63.5 mm (2.5 in), which is twice the size of any other JOFRA dry-block, are both new in the JOFRA product range. With these options it is now possible to calibrate even more temperature sensors at the same time and to calibrate large as well as odd sizes and shapes of sensors, which were not possible to calibrate in the existing range. The compromise compared to the existing models is longer cooling, heating and stabilization times.
ATC-140 & ATC-250 can be used without an external reference sensor, but if a STS-100 reference sensor is connected directly to a B version or the JOFRA reference thermometer DTI-1000, you obtain better accuracies and thereby use the full potential of the calibrators.

Calibration Baths
The JULABO calibration baths are perfectly suitable for applications in calibration laboratories and conform to the requirements specified by DIN ISO 9001:2000. The instruments provide highest temperature stability to ±0.005 °C and temperature uniformity better than ±0.01 °C. The series include models with cooling units for working temperature ranges from -30 to +200 °C as well as calibration baths for temperature ranges from +50 to +300 °C. Reference temperature measurements can be carried out with an additional precision reference sensor. This saves additional costs of a digital thermometer.

ATC - Advanced Temperature Calibrator
Dry-block and liquid bath calibrators. The unique active dual-zone heating block is designed to ensure optimum temperature homogeneity in the calibration zone of the block. This design eliminates the major uncertainties due to heat loss through the sensor-under-test and from the top of the block. The dry-block design combined with the external reference sensor input make the ATC series as accurate as a laboratory calibrator but maintain the speed and portability of a dry-block.
The ATC measures the output from the sensor-under-test directly: Thermocouples, RTD, mV, mA, and V. There is no need for multiple instruments. The JOFRA ATC series saves time by performing automatic stand-alone calibrations. Just run the downloaded work orders from the JOFRACAL calibration software. After completion of the work orders, the results may be downloaded into the computer for analysis, filing, and printing of certificates.

Techne® SB series Fluidized baths operate from ambient to 600°C, and provide a working environment that is dry, easily accessible, and free from the dangers associated with high temperature oil or salt baths. Our fluidized baths are bench standing, requiring only an electrical and air supply for operation.
Air passes through the mass of the AL2O3 particles via a porous plate in the base of the unit separating the
individual particles and suspending them in free air, providing the properties of a liquid bath. Heaters in the bath
maintain temperatures of up to 600°C. All SB Series Baths incorporate stainless steel inner containers insulated
from outer walls, and a safety air pressure switch in the event of loss of air.
Baths are controllable to within +/-1°C, making them ideal as general purpose high temperature environments for
comparison calibration, metal treatment, distillation, and other high temperature applications.
All Fluidized baths are supplied with an initial charge of
aluminum oxide fluidizing media and overspill flange.

Recently, we introduced Metrology Wells, which provide the very best performance in portable temperature calibration. The new 914X Series Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance.
Field Metrology Wells are packed with functionality and are remarkably easy to use. They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. These industrial temperature loop calibrators are perfect for performing transmitter loop calibrations, comparison calibrations, or simple checks of thermocouple sensors. With the “process” option, there is no need to carry additional tools into the field. This optional built-in two-channel readout reads resistance, voltage, and 4–20 mA current with 24 volt loop power. It also has on-board documentation. Combined, the three models (9142, 9143, and 9144—each with a “process” option) cover the wide range of –25 °C to 660 °C.
High performance for the industrial environment
Field Metrology Wells are designed for the industrial process environment. They weigh less than 8.2 kg (18 lb) and have a small footprint, which makes them easy to transport. Optimized for speed, Field Metrology Wells cool to –25 °C in 15 minutes and heat to 660 °C in 15 minutes.
Field environment conditions are typically unstable, having wide temperature variations. Each Field Metrology Well has a built-in gradient-temperature compensation (patent pending) that adjusts control characteristics to ensure stable performance in unstable environments. In fact, all specifications are guaranteed over the
environmental range of 13 °C to 33 °C.

SIKA Precision Temperature Calibrators, TP 38 000 / TP 38 000 E series
Calibrating with every convenience
Working more cost-effectively, safely and reliably in the range from -30°C to 600°C
Thermometers, thermocouples and other temperature sensors are subject to mechanical, thermal and chemical stresses especially in industrial use. This leads with increasing time to a drift that is not predictable.
Since the temperature in industrial processes has become one of the most important indicators of quality, operating safety and service life, the calibration of temperature sensors on site has achieved special importance.
Inaccurate temperature measurements reduce product quality, increase the risk of failure and lead to increased energy consumption.
Only the regular calibration of the sensors provides information on the difference between actual and measured temperature and thus makes the specific drift behaviour visible.
