Taking a break
We're taking a break and will be back soon. We will ship orders on 2017-07-03.
There are many different brands of Dissolved Oxygen meters on the market today. From high-end bench top models, to low cost handheld meters. Some come with custom probes and others can use any off-the-shelf probe. The precision, accuracy and resolution of these different brands varies as wildly as their price. The one thing the embedded systems engineer knows with 100% certainty is that all of these devices are absolutely useless. The embedded systems engineer must have access to the core functional unit of a high-end benchtop device without any of the fluff. The Atlas Scientific™ EZO™ Dissolved Oxygen circuit brings you just that.
Whether you are manufacturing robots, process equipment, sensor arrays, or handheld equipment, Atlas Scientific™ brings you the power and flexibility of a laboratory grade Dissolved Oxygen meter, designed exclusively for robotics.
Welcome to the future of robotic chemical sensing.

The Atlas Scientific EZO class embedded D.O. circuit, is our 6th generation embedded dissolved oxygen circuit. This EZO class D.O. circuit, offers the highest level of stability and accuracy. With proper configuration the EZO class D.O. circuit, can
meet, or exceed the accuracy and precision found in most bench top laboratory grade dissolved oxygen meters. The EZO D.O. circuit, can work with any off-the-shelf galvanic HDPE dissolved oxygen probe/sensor/electrode.
This device reads the D.O. from a D.O. probe/sensor/electrode. This device does not include a D.O. probe/sensor/electrode.
