Frequently Asked Questions
What does 35 ppt mean?
Parts per thousand (ppt) measures salinity. 35.00 ppt is the average salinity of natural seawater, which is the target for most marine and reef aquariums.
Why not just use a bottle of solution?
Once a bottle is opened, the standard can evaporate or absorb contaminants and slowly drift. A single-use sachet is sealed and fresh every time, so your calibration is dependable.
How often should I calibrate?
Calibrate regularly per your meter's guidance, and any time the readings seem inconsistent. Frequent calibration keeps your salinity numbers trustworthy.
Which meters does it work with?
It is designed to calibrate Hanna salinity testers. Always follow your specific meter's calibration instructions.
