Oxygen SAM Photometer Kit, 2.0 - 15.0 Range
SAMs (Single Analyte Meters): Value and Convenience
Single Analyte Meters (SAMs) provide unprecedented economy, simplicity, and accuracy for dedicated photometers. SAMs provide results equivalent to other meters and probes costing much more.
SAM (Single-Analyte Photometer) Kit comes in a cardboard box and contains everything needed to perform 30 tests: K-7513 Vacu-vials Kit, SAM Photometer, 9V battery, light shield, and instructions.
The Indigo Carmine Method
Test kits for environmental and drinking water applications (ppm range) employ the indigo carmine method. The reduced form of indigo carmine reacts with D.O. to form a blue product. The indigo carmine methodology is not subject to interferences from temperature, salinity, or dissolved gases such as sulfide, which plague users of D.O. meters. Results are expressed as ppm (mg/L) O2
