ILT Calibration Services

As our customers have adopted quality manufacturing standards such as ISO17025 and ISO9001, their need for annual NIST traceable re-calibrations has also increased. To meet this demand, ILT has expanded our calibration lab and our standard calibration service offering to include non-ILT light meter and system calibrations (the "C" part numbers on the calibration services Web page).
ILT can also scan 10mm cuvettes for transmission or absorbance ("CSTM" calibrations).
