AC Infinity pH Meter Kit

Excellent PH pen.

I bought this to replace a cheap Vivosun ph pen that just stopped working. its just night and day between the two, for more than double the price you get accurate ph testing, high quality assembly, easy recalibration. Now that i have this pen i don't know how i ever managed with the cheap one or the ph testing chemicals. i heavily recommend this product and suggest that if you are serious about your soilless growing putting aside a little extra to get quality like this.

Great PH Pen

Very accurate comes with all the accessories Ina nice mini travel case bought it because it's way cheaper than Blue Lab PH Pen and was totally worth it!
