Especially saltwater devotees like to regularly measure the oxygen levels of their water. The development department was approached by many of our customers with the request to add an oxygen test to the JBL saltwater test kit.
JBL complied with this legitimate request and integrated two reagents into the JBL oxygen test O2. The proper color charts had already been included in the enclosed color chart booklet. The JBL oxygen test displays O2 content between 1 and 10 mg/l in a well readable and very precise manner. The JBL TestLab Marin now contains eleven tests: pH 7,4-9, KH, Ca, Mg, Cu, NH4, NO2, NO3, PO4, SiO2 and now O2.
In addition, all JBL TestLabs contain high-quality glas cuvettes, dosing syringes, measuring spoons, a thermometer, a ballpoint pen as well as water analysis reports for recording measurement values. The feature of the JBL tests: a laboratory compensation system compensates for water discoloration while taking a reading of the color.
The JBL TestLab Marin was adjusted by the turn of the year.
