MACHEREY-NAGEL has discovered a potential product defect concerning specific serial numbers of the compact photometer PF-3 Drinking Water, PF-3 Pool and PF-3 COD.
We observed that the cuvette slot could be too tight when using a barcoded tube, which can lead to a wrong positioning of the tube in the cuvette slot. The cause of the issue has been
identified and the production process has immediately been changed.
MACHEREY-NAGEL has decided to run a voluntary recall as corrective action. We offer the repair of concerned PF-3 free of charge. Please note that only instruments with
serial numbers beginning with NPF3A and NPF3G within the following serial number ranges can be concerned:
- NPF3A1834 - NPF3A2261
- NPF3G1874 - NPFG2159
