PYROS 125
It cover a range from -24 to 125 °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 Pyros 125 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 has two parallel holes with a diameter of 13 mm in which the reduction inserts are inserted 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 provide upon request up to 1 mm in diameter.

PYROS 375 It covers a range from 10 °C above ambient temperature up to 375 °C. It has a stability ±0,15 °C and an accuracy of ±0,25 °C at 150 °C and of ±0,5 °C at 375 °C. The time taken to reach 375 °C is just 20 minutes and it takes 40 minutes to reach 100 °C from 375 ° C. This allows to save time during calibration operations that requires more than one verification point. The calibrator has a hole with a diameter of 26×150 mm in which the reduction inserts are inserted to adapt the diameter of the probe to be calibrated to the calibrator. There are 3 inserts available with holes ranging from a diameter of 3,2 to 12,7 mm while other holes are provided upon request up to 1 mm in diameter. The appliance innovative ventilation system allows the calibrator to keep the temperature on the top of the oven lower compared to competitors’ oven. The flow of air on the upper part of the oven is diverted to the rear of the appliance by a tangential flow that touches the calibration well. As a result, the heads of the thermocouples, which contain the connection terminals o f the compensated cables, remain at a considerably lower temperature reducing very much the compensation errors produced by the heads heating.

PYROS 650 It covers a range from 15 °C above ambient temperature up to 650 °C. It has a stability of ±0,3 °C and a all -range accuracy of ±0,9 °C. The time taken to reach 650 °C is just 35 minutes and it takes about 60 minutes to reach 100 °C from 650 °C. This allows to save time during calibration operations that require more than one verification points. The calibrator has a hole with a diameter of 26×150 mm in which the reduction inserts are inserted to adapt the diameter of the probe to be calibrated to the calibrator. There are 6 inserts available with holes ranging from a diameter of 3,2 to 17,5 mm while other holes are provided upon request up to 1 mm in diameter. The appliance innovative ventilation system allows the calibrator to keep the temperature on the top of the oven lower compared to competitors’ oven.

As a result, the heads of the thermocouples, which contain the connec tion terminals o f the compensated cables, remain at a considerably lower temperature reducing very much the compensation errors produced by the heads heating.
