Request For Recalibration
While Coulometers require no user calibration, the Coulometer is an electronic measurement instrument and eventually will require electronic calibration. UIC recommends all Coulometers have an electronic bench calibration and analytical QC every 2 to 3 years. The procedure uses bench equipment traceable to NIST standards to return the instrument to factory new performance. The performance is verified by analytical laboratory QC procedure as the final verification. Please contact us to obtain a return authorization number and shipping instructions.
