Water testkits

Any successful aquaculturist will tell you that good water quality is the secret to good survival and growth. Electronic measuring devices can be very expensive, however, and can be costly in terms of repair and calibration. Chemical water quality analysis has always been an alternative, but test kits in the past were confusing to even the most experienced chemists. Simple and cheap water test kits for farmers are now widely available for all of the important water quality parameters. Nam Sai has been using them for a number of years for both on-farm spot testing and also for university-coordinated research.

Being quite small and light, water test kits can easily be sent by registered mail to farmers located anywhere around the globe. Alternatively, large orders can be sent by courier or by freight. There is a discount of 5% for orders of 10 kits and 10% for purchases of 50 kits or more.
