I found this product to be a quality product for a very reasonable price. The monitor does exactly what it's supposed to do and I'm very happy with it. The kit comes complete with calibration fluids and electrodes.

Delivered via reglar air mail to the Netherlands within the expected lead time.
Would definately recommend this company to others.

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.

final result is beautiful and useful. I would recommend. incomparable value of quality workmanship and quality materials ...

very good product...i will buy it,every time,again.very cheap for a super part..it really works good

bon rapport qualite prix

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

Sehr gutes Gerät das die Salinität direkt in einer Dauermessung anzeigt! Kein handtieren mit Batterien oder kleinen Anzeigen. �berprüfung mit Aqua-Medic Hydrometer und umrechnen mit dem Aqua-Calculator ergibt eine 100% übereinstimmung. PH-Anzeige wie erwartet genau. Geprüft mit Eichlösung. Gro�e beleuchtete Anzeige, blau hinterleuchtet. Wahnsinn zu diesem Preis. Achtung! Gerät zeigt Salinität in ppt (PSU). Umrechnung nach Dichte kann mit dem oben erwähnten Programm leicht erfolgen. Nochmals, Dauermessung der Salinität. Wirklich Klasse!

excellent produit et très précis.bravo

Product easy to set up, after careful calibration, it works like a charm.
