The ETC Series is the ideal dry block temperature calibrator when time is the critical factor and the highest accuracy is not a requirement. The block heats up to 100°C per minute and stabilizes in just 3 minutes! The small size and light weight, fit perfectly in a tool box, making it the perfect field calibrator to verify sensors in difficult to reach places  

Rugged construction, featuring stainless steel and rubber side panels, make the instrument suitable for many years of service in an industrial environment.

• Temperature range from -10 to 400°C (14 to 752°F) with 3 models
• Accuracy to ± 0.5°C and Stability to ± 0.05°C
• Time saving fast cooling and heating times
• Easy-to-read multi-information display 
• Customizable stability checkmark with countdown timer
• Set exact temperature desired to a resolution of 0.1°C
• ETC 400R, small lightweight IR calibrator
• Lightweight and easy to carry

ETC-400 R for infrared thermometers The ETC-400 R is designed for optimum speed in connection with calibration of infrared thermometers. The 36 mm target provides the optimum size for reliable calibration of infrared thermometers in the process industry as it is designed for high accuracy and long-term stability while maintaining speed. With regard to the coating of the target it has been especially designed for space technology applications, which secure long time performance under high temperature influence. In combination with the shape of the target it ensures the emissivity of 0.96. If higher accuracy is required, and for recalibration, a 3 mm external JOFRA STS reference probe can be placed under the surface of the target.

Super fast heating - ETC-400 A dry-block The ETC-400 A is designed for optimum speed. The heating block is built around a highly efficient heating element. The insertion holes for the temperature device under test are located around this element. To reduce mass and increase effectiveness, there is no removable insertion tube; the holes are drilled directly into the block. The minimal mass offers an extremely fast heating and cooling time. The different layouts also make it possible to use an external JOFRA STS reference probe during the calibration. Choose the combination of holes that best suits your needs from our various design combinations. If your application requires a dry-block that can handle large sensors or more than one sensor at a time, we offer several other JOFRA dry-block calibrators that can meet your needs.

 Cooling and heating - ETC-125 A dry-block The ETC-125 A is a simple yet effective tool for verifying temperature instruments that also require references below ambient temperatures: e.g. air-conditioning and cold counters. The predrilled holes allow the use of an insertion tube in the largest bore. This increases the flexibility to match many sensor-under-test sizes.

Shipped with 115VAC Power Supply and US/Canada 115VAC Main Power Cable. Other options available if needed. 

JofraCal calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermo switches, pressure gauges and pressure switches. It may be used with our well-known temperature calibrators as well as with pressure and multifunction calibrators. 

JofraCal calibration software provides an entirely automatic calibration of sensors and a semi-automatic calibration of the complete process loop by means of a PC. The software handles the comparison between the process readout value and the reference value, controls the complete calibration procedure, stores the results, and provides a calibration audit trail through hard-copy certificates. All calibration data are stored for each sensor to monitor drift and optimize recalibration intervals. A scheduler feature allows planning of future calibrations.

• Reduce operator time by automating calibration procedures
• Calibrate up to 24 sensor simultaneously
• Comply with quality systems by documenting results and procedures
• Reduce sources of error by using stored procedures and set-ups
• Use with our temperature, signal, and pressure calibrators
