Portable temperature calibrator - Pyros 375
Product Description
It covers a range from 10 °C above ambient temperature up to375 °C. It has a stability of ±0,15 °C and anaccuracy of ±0,25 °C at 150 °C, of ±0,35°C at 375 °C.
The time taken to reach 375 °C is just 20 minutes and ittakes 40 minutes to reach 100 °C from 375 °C. This allowsto save time during calibration operations that requires more thanone verification point. The calibrator has a hole with a diameterof 26x150 mm in which the reduction inserts are inserted to adaptthe diameter of the probe to be calibrated to the calibrator.
There are 3 inserts available with holes ranging from a diameterof 3,2 to 12,7 mm while other holes are provided upon request up to1 mm in diameter.
The appliance's innovative ventilation system allows thecalibrator to keep the temperature on the top of the calibratorlower compared to competitors' ones. The air flow on the upper partis diverted to the rear of the appliance by a tangential flow thattouches the calibration well.
As a result, the heads of the thermocouples, which contain theconnection terminals of the compensated cables, remain at aconsiderably lower temperature reducing very much the compensationerrors produced by the heads heating.
