ATI Multi Standard

ATI® Multi Standard is a seawater reference solution containing fixed concentrations of salinity, alkalinity (carbonate hardness), calcium, magnesium, potassium, and strontium. By comparing test results with the reference solution values, you can check the accuracy of your test kits and salinity measurement devices (refractometers, hydrometers, conductivity meters, etc.) and calibrate them if necessary. ATI® Multi Standard is based on ATI® Absolute Ocean, which perfectly replicates natural seawater. ATI® Multi Standard is stable and undergoes strict quality controls at the ATI® laboratory.

With ATI® Multi Standard, you can check the following values:

• Salinity: 35 PSU
• Alkalinity (Carbonate Hardness): 7.5 °dKH
• Calcium: 421 mg/l (ppm)
• Magnesium: 1,313 mg/l (ppm)
• Potassium: 408 mg/l (ppm)
• Strontium: 8.1 mg/l (ppm)

Note: Close bottle immediately after use.
