This is a great tool for when you need to test
your pond or aquarium pH. It is a fast and accurate meter. What you save in
buying drop type test kits will more than pay for this meter! And those kits
are not usually very accurate. You will never have to guess which color the
ph Strips are closest to! It is fast and simple to use. Just dip it in the
pond, aquarium or swimming pool and read the reading on the digital display
in just a few seconds This unit comes in sturdy clear plastic case with
calibration screwdriver and users guide!
