ProductsWater Test Kits
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 and can be costly in terms of repair and calibration. Chemical analysis of water quality has always been an alternative, but tests in the past confused even the most experienced chemists. Simple and cheap water testing kits for farmers are now widely available for all important water quality parameters. Nam Sai has been using them for a number of years for on-farm trials and also for research coordinated by the university.
Being small and lightweight, water test kits can be easily sent by registered mail to farmers located all over the world. Alternatively, large orders can be sent by mail or freight. There is a 5% discount for orders of 10 kits and 10% for purchases of 50 or more kits.
The following water test kits are available.
