  • Product info

The EJB 240-1402 covers a range from -24 to 140°C. It has a stability of ±0,05°C and a precision of ±0,25°C.

The time taken to reach -20°C is just 17 minutes and the time to reach 120°C is just 20 minutes: this allows considerable savings in terms of time during calibration that requires more than one verification point.

The excellent performances of EJB 240-1402 are due to the Peltier cells that heat and cool the thermal block and to the material with which the thermal block itself is made. This material provides an axial and radial uniformity typical of higher end calibrators.

The calibrator EJB 240-1402 has two parallel holes with 13 mm diameters (one hole with 19 mm diameter EJB 240-1401 version). The reduction inserts are put into the holes to adapt the diameter of the probe to be calibrated to the calibrator.

There are 7 inserts available with holes ranging from a diameter of 3,2 to 11,1 mm, while other holes are provided upon request up to 1 mm in diameter.

These innovative calibrators have been designed for on-site applications and for the severe conditions of the naval and marine sectors.
Their ease of use, compact and practical design, make them unbeatable in industrial processes where the verification of the temperature measurement systems is a key issue for the control of the process and the quality of the final product.

Special attention was paid to reduce weight, size and to reinforce robustness by using an aluminium body and aluminium and stainless steel for many internal parts.
Each calibrator is tested in our laboratory and calibrated with our measurement samples in accordance with the international standard. At this stage all the functions are checked against reference parameters and a calibration report is issued.
The thermal part of these calibrators is made of a metal block heated with resistors or with Peltier thermoelectric modules.

In the metal block there are one or more holes in which the interchangeable inserts are placed.
The standard inserts available make the calibrators versatile in order to adapt them to the calibration of the temperature sensors with the most common diameters in use. It is also possible to create inserts with special holes upon request.

The equipment provided as standard on each oven includes the power supply cable, the tweezers to extract the inserts, the connection cables of the thermostats, a fuse kit, one or more of the inserts most commonly used, the instructions manual and the calibration report.
