Direct Reading Titrator Method

Dropper Bottle Method
Direct Reading Titrator Dropper Bottle
The Direct Reading Titrator is a 1.0 mL microburet calibrated to allow direct reading of the test result. Each Titrator has a specific range, but may be refilled to test higher concentrations. The dropper bottle test uses bottle tips which deliver a consistent standard drop size to add titrant to the sample. As with the drop count test, the number of drops used to complete the reaction is multiplied by a given equivalence factor to determine the concentration.

EDTA titration is used for all hardness determinations, with a red to blue endpoint. Both total and calcium hardness buffers include inhibitors to eliminate metal interferences. All results are as CaCO3; some kits also express results as gpg. L1017202, which is recommended for salt water analysis, includes a conversion factor for Ca2+.
