Perfect item! Good seller!

très rapide et super produit

Awesome bit of kit for the money. I use 1 on my calcium reactor. I am shortly ordering a ph monitor to run on the DT as I am so pleased with this one.

Very good item. Fast shipping. Totally satisfied.

Por el precio que tiene, funciona muy bien. El electrodo, aunque muy básico va perfecto. Lo calibré cuando lo instalé y lo compruebo periódicamente, pero no he tenido que volver a ajustarlo. Solo tiene un punto de ajuste, pero como normalmente trabajo en torno a pH 7, no son necesarios más puntos. Una compra recomendada.

super comme produit et peu chers

This is a great product for the price, the only down side was there were no English instructions included but simple setup instructions are included within the product description. I found this product to be very accurate and would recommend it. It also arrived within a few days and I live in the UK.

The item arrived in 9 days. Cakibration is only on 1 point but is spot on . Great item.

This item is perfect!!!!!
