HACH 吸管模塊，包括1厘米石英比色池及安裝組件 DR 5000 UV-Vis Spectrophotometer Sipper Module

The DR 5000 Spectrophotometer Sipper Sampling Module uses a peristaltic pump to aspirate samples into a flow cell for readings. After the reading is taken, the sample is either returned to the user or dumped to waste.

The Spectrophotometer Sipper Sampling Module provides improved measurement accuracy, because the same optical characteristics exist for both blanking and reading, and when comparing measurements of different samples.
