Очень нужный прибор в морской аквариумном деле. Советую всем. Не пожалеете потраченные деньги.

Spot on for service and price

Very good item with great accuracy

This unit is simple, accurate and very stable. Once calibrated it showed my previous float type measurement was wildly wrong and caused too high salinity. Once I corrected the mix and monitored, my tank has significantly improved. Clear readout shows PH day/night variance and keeps minor changes in salinity. Highly recommended.

easy to use and so far seems accurate

Accurate and stylish meter. Must have this monitor...

I've had mine set up and running in tandem with my GHL probes and the results patch pretty acuratly for such an affordable device. well worth the money, same pruduct with Deltec badge cost three times as much

Extremely satisfied with the product!

works great, well worth the money

Would recommend this and its close enough to my refract meter and my Hanna PH checker so its top marks from me.
