Water pollution/quality test kits + meters

[Ukwildlifeo]

Im looking for testing kits or electronic meters for testing water for pollution/water quality.

So far the list is to measure:
- pH
- Nutrients – phosphourous + Nitrate
- Salinity - Conductivity#

Can anyone recommend some good kits or meters for these? Preferably the cheapest accurate version!

for finding how good a water body is you cant beat the biological monitoring working party (BMWP) is a procedure for measuring water quality using species of macroinvertebrates as biological indicators

most off the shelf test kits are not very accurate no matter the kit you use,

what do you want to look for and why?

you can get information from the EA under the freedom of information act if your particular water body happens to be visited by them as part of routine or post event monitoring / testing
