Great item for the price. Controls my calcium reactor and CO2 regulator (fish street one). I would advise getting an extra calibration fluid however for maintenance use in the future.

works fine, good quality for money. could have a more decent probe though

The hysteresys seems to be a little to big (0,15), bat does its best for the price.
I reccomand it.

Excellent product ! Simple, precise, not expensive...

8 days only of transport for France.

For freshwater, ask the model "A" !

I bought this product with a co2 regulator at fish-street and quality its very good.. they arrived to my home in 1 week.

Both work together perfectly.

super good deal

Easy to setup and use, but the PH setting is very sentive.

relacion calidad precio excelente

It's a very good ph controller,easy and simple to setup. I am very happy with the choice.

It's good because it's cheap, it works quite ok with some minor inconvenients: with a pH set at 6.8 it opens the em valve at 6.85 and closes it to 6.71; probe cable too short. pH probe works ok, no em interferences, properly packed both the original one and the supplementary one I ordered
