Bluelab Guardian Monitor Inline Wi-Fi for Real-time Measurements of PH, Temperature and Conductivity (TDS/PPM) in Water with Calibration, 3-1 Digital Nutrient Meter for Inline Dosing Systems

It's so better made than other makes and the ph probe the same as my blue lab muti meter sp spot

Its just the bit of kit you need if your a beginner in hydro or a real pro gives you the readings and info you need at at moments notice and its accurate witch is most important price wise just hard to beat buy now if you need a ec/ph meter that really works

Have it for couple of months so far good Quality made long probes leads

expensive but worth it. Accurate and just awesome.

Brilliant

I ordered the wrong item (pics in ad were not accurate displayed bluetooth option) not realizing they have bluetooth options for the same product for 3$ less from the same company! Customer service promptly fixed the problem and express shipped me the correct one. The product itself is awesome best for a system with a water tank. (Must have for the serious grower)

Strumento fantastico che vale ogni centesimo speso, si calibra facilmente e consente di risparmiare molto tempo data la possibilità di visualizzare i dati al volo. Lo uso da più di 16 mesi con ancora la stessa sonda pH senza alcun problema. Top!

FUNCIONA PERFECTO, facil calibracion y medicion 100% fiable bluelab es sinonimo de calidad un 10

genau messungen sind hier das A und O

Top rien a dire un peu cher mais quel gain de temps et ça fonctionne très bien
