1. The Chlorine Dioxide Measurement Revolution: Precision Without Compromise

If you work with chlorine dioxide, you know that accuracy isn’t a luxury—it’s a necessity. Until now, users often faced a dilemma. Either they relied on inaccurate test strips, which often fail at high concentrations, or they invested in expensive, complicated laboratory equipment. The Mara CIO2 WR® (Wide Range) breaks this paradigm. As the world’s first device of its kind, it enables precise determination of chlorine dioxide concentration across an impressive range of 10 to 4,000 ppm.

Why is this important? Especially when producing chlorine dioxide solutions (such as CDS/CDL), we often operate in ranges that simply overwhelm conventional measurement methods. While test strips fade at high concentrations or color scales must be interpreted subjectively, the Mara Quantics meter delivers a digital, objective result. It’s the end of uncertainty. With an average rating of 5.0 out of 5 stars, our customers confirm that this device has redefined the standard for mobile analytics. It’s not just a tool; it’s the assurance that your solutions have exactly the concentration you intend—reliable, reproducible, and professional.

2. Intelligent Spectrophotometry: The Molecular Fingerprint

What actually happens inside the Mara CIO2 WR®? While other devices rely on chemical reactions, this device utilizes the physical properties of the chlorine dioxide molecule. The technology is based on spectrophotometry. Every element and every compound has a kind of “optical fingerprint.” The device sends light of a specific wavelength through the sample in the optical cell. The way in which the chlorine dioxide absorbs this light is detected by the sensor with the highest precision.

This process has a decisive advantage: it is purely physical. For you, this means that the measurement result is available within a few seconds. But the technology goes even further. By identifying the specific spectrum, the device can even detect impurities in the solution that would skew the measurement result using conventional methods. Despite these highly complex processes inside, operation remains incredibly simple for you. You control the entire measurement process via an intuitive one-button operation. You don’t need a technical degree or lengthy training. The Mara CIO2 WR® makes high-end analytics accessible to anyone who values excellence—all packed into a compact device weighing just 500 grams.

3. Cost-effectiveness through maintenance-free operation: No reagents, no hidden costs

An often-overlooked factor when purchasing measuring instruments is the ongoing costs. Many photometers on the market entice buyers with a low purchase price, but then lock users into using consumables such as tablets, powders, or special reagents. The Mara CIO2 WR® takes a radically different approach: It is completely maintenance-free and requires no reagents. Once you’ve made the investment, the device is yours, and you’ll never have to buy test kits again.

This not only saves you money but also saves you the hassle. Do you know that feeling when you want to take a measurement and realize the reagents have expired? With the Mara Quantics measuring device, this scenario is a thing of the past. Its durability and robust design (14 × 12 × 7 cm) make it the ideal companion for mobile use. The package includes 3 optical cells, so you can start taking measurements right away. We ship the device in a sturdy carrying case that protects the sensitive optics while on the go. In a world where resources are becoming increasingly scarce, we rely on a sustainable measurement principle that produces no chemical waste and provides reliable service for years to come. That’s efficiency that pays off.

4. All-Inclusive Service: The Plus Zone and Global Support

Purchasing a Mara CIO2 WR® is just the beginning of our journey together. At Mara Quantics, we believe that a first-class product deserves first-class service. That’s why our service doesn’t end when we ship the package. Every buyer receives exclusive access to our “Plus Zone”. This is a protected area where we pool all our knowledge: From detailed manuals and informative instructional videos to comprehensive FAQs that go far beyond simply operating the device.

Should you ever need technical assistance, Medalab Support is here to help and ships worldwide with a fast turnaround time of often just 24 hours to a maximum of 3 days (plus shipping time via DHL or similar) . And if the device does not meet your expectations, you benefit from a 14-day return policy. However, we are certain: Once you have experienced the precision and simplicity of the Mara CIO2 WR®, you will never want to go back to other measurement methods. Despite the current “out of stock” status (due to overwhelming demand) as of March 2026, it’s worth staying tuned: the quality and safety of your chlorine dioxide applications should never be left to chance.
