I was surprised of this item tbh. I was thinking crappy cheap metre. I've been carrying this in my back pocket around some harsh places and had it in some temperature changes up and down to measure salt wherever I go..... As medical personell I have a good supply og sterile water and I'm surprised again and again after the crap I put it thru it still comes out in 0 sal on sterile water. no recalibration no fuzz. Big surprise tbh

Best bit of kit that every reef tank & marine tank owner should have , very easy to use,fantastic quality & accurate. Would not be without one.

Easily calibrated and accurately .

Does the job of measuring the salinity very easy, works realy good
