AC Infinity Replacement Probe for Hydroponic Meter PRO Kit, Measures Acidity, Alkalinity, Temperature, EC, TDS, & Salinity with ±0.01 pH Accuracy, Water Hydroponics Plants, Gardening, Aquariums, Pools

This is extremely accurate and so far in the last 4 months I have only needed to calibrate it once which was when I first received it. I made the mistake going with a competitor well names brand and so far everything that I have bought from them has need to be replaced. AC Infinity is the brand that I suggest and I hope you don't make the same mistake as me. And a bonus, they have amazing support if you have any problems at all.

This is a replacement probe for the Hydroponic Meter Pro kit AC Infinity. I have a considerable amount of AC Infinity equipment and can say this meter and replacement probe are equally high quality as the rest of the ACI line. The probe is well packaged, as pictured. The probe itself comes inside a small box with an inner plastic tube containing the replacement probe. Replacement is easy, but there are handy step-by-step instructions if you need them. AC Infinity makes top-notch equipment for a reasonable price and I have never been disappointed with any of their equipment or replacement parts.

I was looking for a replacement probe end for my AC Infinity meter and came across this one from the same manufacturer. Needless to say, I'm very happy with it because it is a direct replacement for the one I had, not an off-brand clone. Highly recommended, especially for Amazon's low listed selling price.

Got this to replace my probe on my account Infinity pro and it fits great. Love that they made it replaceable. Top notch quality from AC Infinity as always. Definitely recommend if you bought the pro probe.
