Bin sehr zufrieden, funktioniert sehr gut! Shop sehr gut!

Ph works really fine, no more ph test kits (have to calibrate with more liquids if you have any doubts over time).
Salinity needs no calibration but, becareful with air bubbles&etc. trapped inside the probe, if it suddenly swings too much about 3-4 ppt.Check you temp also.

Very useful and good performance for this price.

bon rapport qualite prix

Good Product, but the internal battery is bad, i need to leave connected in external charge all time !!

it is consistently accurate and have a rechargeable battery backup
After calibration which takes 5 min this device is consistently accurate and have a rechargeable battery backup which means calibration can't be lost
make sure to rinse the salinity probe with alcohol to achieve an accurate reading

A very good monitor I recommend to everyone.

I have been using mine for three months now and after fiddling with it I get reletively accurate readings. setup is easy and readings are clear. PH works well. Salinity gets thrown around with temperature changes. No biggie if you know what to expect.
Very happy with my purchase.
