MX3 Hydration Testing System

The MX3 Hydration Testing System - Pro Version

MX3 is about to change what’s possible for health and fitness diagnostics. This is the first simple, reliable way to measure and track hydration—anytime, anywhere.

The MX3 Pro System uses a saliva sample from the tip of the tongue to take a lab-grade hydration measurement in seconds. Using the portable handheld meter, disposable test strips, and an easy-to-use app, athletes, coaches and team managers can finally measure, track, and manage hydration.

With MX3 Pro, one simple device gives you control of health and performance.

Hydration Matters

Proper hydration is essential to performance. Detrimental physical and cognitive effects begin to manifest at as little as 1-2% body mass loss (BML). This results in reduction in muscular endurance and strength, as well as fatigue and impaired decision making. Staying hydrated is therefore essential to performance. MX3 helps athletes avoid these issues by staying hydrated when it matters most.

Hydration Matters

Measure. Track. Perform.

Say goodbye to time-consuming and inconvenient testing. No other device measures the body’s actual hydration levels immediately and accurately in any setting. With frequent testing, you can gather the data you need to develop and optimize personalized hydration strategies.

Measure. Track. Perform.


Improve performance by preparing and recovering better. Testing hydration the day before or hours before an event allows an athlete to be ready when it matters. And testing after physical exertion will provide the data needed to develop the best rehydration and recovery strategies.

Sweat Sodium Testing

The MX3 Hydration Testing System uses a single device to run two different tests in real-time that tell you how much fluid to drink and what kind of fluid will best replace the electrolytes you lose during exercise.

The sweat test measures sodium levels, so you can replace lost electrolytes and customize your hydration strategy with the right fluids. With MX3, you can test, track and hydrate effectively to optimize your performance and reduce injury.

Sweat Testing

Use the MX3 LAB anytime, anywhere. Simply take a quick saliva or sweat sample on the field or in the locker room.


MX3 is scientifically proven to measure biomarkers from saliva as accurately as a laboratory osmometer.


Your hydration level is recorded within seconds of taking a saliva measurement, and results immediately upload to your app.


The LAB can be used over and over by one person or entire teams. Just replace the disposable test strip after each measurement.


Test strips load easily into the LAB, and saliva measurements are made by simply placing the strip on the tip of the tongue.


The LAB can be used with or without Bluetooth or Internet access. Measurements can be taken anytime for immediate readings, then stored for later upload.
