Indiana Standards Laboratory offers ISO/IEC-17025 accredited calibration of psychrometers, humidity meters and humidity chambers, along with all types of temperature measuring equipment. In the laboratory humidity meters are calibrated using a Thunder Scientific 2500, the industry standard for high-precision humidity calibration. For on-site calibrations, humidity meters are calibrated using our portable humidity generator and precision Vaisala humidity probe. ISL calibrates using standards traceable to a National Metrological Institute such as NIST(US) for various manufacturers’ instruments including but not limited to: Fluke, Vaisala, Extech, Flir, Dickson, Control Company, and VWR.
