Inductance Calibration - Inductance Calibration Standards and Service
IET Labs is a premier calibration laboratory that is accredited by A2LA for Inductance-Measure and Inductance-Generate.
We can calibrate most inductance standards with uncertainties as good as 0.01 % + 50 nH.
Please contact our sales staff, by phone or online, who will be pleased to give you a quote for the calibration or repair of your equipment.
IET Labs maintains well over 30 IET/GenRad 1482 Inductance Standards that cover the range of 10 µH to 10 H in a 1, 2, 5 series. These standards are used for both Inductance-Generate, and Inductance-Measure when transfer measurements are performed. Most 1482s are calibrated traceable to the SI, through a National Metrology Institute mainly NPL in the UK.
IET Labs uses 2 main LCR Meters for Inductance-Measure using direct measurements or transfer from standards that are calibrated traceable to the SI, through a National Metrology Institute (NPL): 1.) The GenRad/IET Labs 1689 and 1693 Digibridge with a CMC1 down to 0.01% + 50 nH.The GenRad/IET Labs 1689 and 1693 Digibridge are the workhorse for both direct inductance measurements and transfer measurements at IET Labs. All measurements are made using delta % to improve resolution on the Digibridge. Customer's inductance standards are measured 3 times over 2 days with the results being averaged together for the final calibrated value. The test program we use compares the calibrated inductance values from each of the 3 calibration runs as well as historical calibration numbers to check stability of the inductance standard. 2.) The IET Labs 7600 Plus Precision LCR Meter with a CMC1 down to 0.05% + 120 pH. The 7600 Plus is primarily used for measurements above 10 kHz.
