SiS Sensoren Instrumente Systeme GmbH


DOA Dissolved Oxygen Analyser Accessory Sets

SiS offers three kinds of accessory sets and a chemical set for the use with the DO Analyser.

Chemical Set

QuantityDescriptionManufacturer
500 gNaOHMerck
1000 gNaIMerck
1000 gMnCl2 x 4H2OMerck
500 gNa2S2O3 x 5H2OMerck
2
Titrisol KIO3, 1/60 mol/l (prepared standard solution) OR
KIO3 salt
Merck

All chemicals are of pro analysis grade or better. The quantities are sufficient for at least 2000 sample titrations. Other quantities / weights on request. Sulfuric acid (H2SO4, 50%) is also required, but should be purchased locally due to transportation restrictions. The prepared Titrisol standard has to be diluted. To avoid dilution of 1:100 we recommend dilution of 1:10 and usage of 1 ml pipettes for the standard determination. For blank determination, a 0.1 ml pipette may be used with the prepared standard or a 1 ml pipette with a diluted sub-standard. For highest precision the usage of weighted and diluted KIO3 salt is recommended.

Economy Set

This is the minmum requirement with no calibration facilities. Calibrated bottles are provided.
