Expert Calibration

Accredited Certificate #3964.01

Incorrect functioning or performance of instrumentation or an invalid calibration can negate and nullify your test data. AES supplies customers with equipment durability and the required calibration to certify compliance with industry standards and repeatability of final results.

By calibrating environmental test chambers that are NIST traceable or A2LA accredited, we assure ongoing dependability and precision with the chamber's temperature, humidity, controllers, recorders and sensors. Our test chambers are manufactured with an option to employ a chilled mirror concept which provides highly accurate calibration.
