Hach 46646-00 Lamp Recalibration Filter Assembly for DR2000/2010 Spectrophotometers

This Hach lamp calibration filter assembly is intended for use with DR/2000 (with software versions 2.0, 2.2, 3.0 and greater) and DR/2010 spectrophotometers. Do not perform this procedure if your instrument has 1.261 or 1.27 software. Perform the adjustment any time the lamp assembly (Cat. No. 46644-00) is replaced and periodically for optimum performance. The adjustment assures the best possible accuracy and repeatability. Use the Calibration Filter Assembly (Cat. No. 46646-00) to make the adjustment.

The box contains the 808nm filter (P/N 46883-00) seen in photos.
