Atlas Scientific specializes in merging the biological sciences with modern day embedded computer science. Atlas Scientific engineers understand the complexities of biology, modern embedded computer systems and the strict level of accuracy needed to take true scientific grade readings. Oxidation Reduction Potential (ORP) is a part of electrochemistry that is complex and commonly misunderstood. This made finding an ORP Circuit virtually impossible. The Atlas Scientific ORP Circuit (our fourth generation ORP Circuit) has put an end to this problem. Now, the engineer can easily incorporate a modern ORP Circuit into a design without having to learn complex chemistry and analog signal processing. With a wide operating voltage (2.5V to 5.5V) and a simple asynchronous serial communication protocol, this easy to use ORP Circuit is specifically designed for modern embedded computer systems.

The Atlas Scientific ORP Circuit is designed for both continuous and intermittent readings. After calibration, the ORP Sensor can be immersed in a liquid and operate continuously for 12 months before recalibration is recommended.
