## Description

Product description

Review: Easy Integration into my Saltwater Aquarium Monitoring System - I am currently using Atlas Scientific pH circuit and now added their ORP circuit to my Aquarium monitoring system. Their example software was a good starting point and within a day I had it running on an Arduino MEGA microcomputer with 3.2" LCD Touch display. I am planning to added calibration and alarm features to the software as it will be used to monitor a Denitrating filter system which can be a bit tricky starting up and keeping dialed in The readings are stable and seem accurate.
Review: Works perfectly - Very good product. Worked exactly as advertised. Saved a little money by ordering through desertcart vs other vendors.
