Hygrometer COFRAC calibration

Aérométrologie proposes calibration services in hygrometry in both its laboratories. Our services: Les Ulis: Calibration at dew point temperature between -30 and 60°C and at relative humidity between 5 and 95 % for dry-bulb temperatures between 5 and 60 °C. We use generators or climatic chambers. Pernes-Les-Fontaines: Calibration at dew point temperature between -80°C and +90°C (**) including under pressure until 7 bar from -80°C to 0°C and at relative humidity between 0% and 100% for dry-bulb temperatures between -20°C and +90°C. We use generators with recirculation or a climatic chamber. Instruments covered: All capacitive or resistive portable hygrometers Condensation hygrometers Lithium chloride Hygrometers working by air sampling Hygrometers working by air sampling Psychrometers Accreditations in hygrometry: N°2-1456. (-30°C to +60°C dew point temperature), Les Ulis (91) N°2-1905. (-80°C to +90°C dew point temperature), Pernes-Les-Fontaines (84) Scope is available on www.cofrac.fr
