Expand Your Water Quality Monitoring with EXO-S Sondes

Top 7 Ways New EXO Sondes Expand Your Water Quality Monitoring

We developed the EXO Sonde Platform as the ultimate tool to help you monitor and protect your world. For the last ten years, EXO has not only led the industry but continued to grow with new features, new sensors, and now new sondes. 

We're excited to welcome the newly released EXO-S Series Sondes as shorter, lighter, more affordable, and more sustainable versions of our best-in-class EXO Sondes.

Let's look at the top 7 ways the new EXO-S Series Sondes can help you do even more in the field!

1) Like the EXO You Know, but Smaller

 These small sondes are purpose-built without a battery compartment but still provide the same high-quality data and reliable performance for applications where external power is available. Just like our standard EXO Sondes, there are three sonde models in the EXO-S Series to choose from. 

EXO1s Sampling in River

The EXO1S has the smallest diameter with four sensor ports to accommodate the most common water quality parameters (or any combination that works best for you). Combine this sonde with an EXO handheld for an extremely powerful discreet sampling solution. Plus, the removable bail gives you easier access to the cable connector to make sampling more convenient.

EXO2s River Sampling

The EXO2S features seven ports for maximum sensor customization. Add our industry-leading central wiper to keep sensors clean from fouling during extended deployments. This sonde also includes an auxiliary port for integrating third-party sensors or daisy-chaining sondes.

EXO3s River Water Sampling 

The EXO3S has five ports, including the central wiper port, giving you flexibility in sensor selection as well as anti-fouling. This sonde also includes native SDI-12 communications for streamlined integration into collection platforms or installations. 

2) Minimal Size for Maximum Options

The compact design is the most apparent difference between these and our standard EXO Sondes. Whether you're deploying in field stations, pipes, or data buoys, having more compact equipment and extra space can make for easier operations and more peace of mind. With up to 40% reduction in length and 30% reduction in weight*, EXO-S sondes can fit into tight spaces and be more easily hidden. 

3) Sampling Versatility

Because of the decreased size and weight, EXO-S Sondes make spot sampling with EXO easier than ever. As mentioned earlier, the EXO1S is perfect for spot-checking water quality with a handheld or EXO GO. This can be a great option if you already use EXO for continuous monitoring and want extra versatility in application types.  

EXO also offers extra sensor options not found on other sampling systems, such as fDOMRhodamine, and NitraLED UV nitrate.

4) Explore your Environment

Discover new ways to measure water quality by adding these are smaller, lighter sondes to autonomous or remote vehicles. The rQPOD lets you collect spatial data in minutes and gives you safe access to locations that are difficult or dangerous to access on foot or by boat.  

EXO-S is also an excellent choice for data buoys and floating platforms where weight and buoyancy are factors.

5) Lose the Alkaline Batteries

Because EXO-S is powered externally, you don't have to worry about replacing or disposing of alkaline batteries – making these a more environmentally friendly option for continuous monitoring. Simply integrate into a powered system – like a buoy or field station with solar power – and set your deployment. 

If you're taking an EXO-S Sonde out for sampling, the EXO handheld, EXO GO, or rQPOD will provide enough power for a full day in the field. 

6) Replacing Older Equipment

I'll cover this in more detail in a future blog post, but for now, I'll tell you the release of the EXO-S series comes with the discontinuation of the remaining 6-Series sondes. The EXO1S makes an excellent replacement for the 600R or 600XL, while the EXO3S is an ideal upgrade for the 600OMS or 6820 V2 – offering extra sensor ports, more sensor options, enhanced data quality, and additional features.  

7) Affordability

A bonus of the new EXO-S series is the lower price point compared to the standard EXO Sondes. Plus, removing the reliance on batteries provides a few long-term benefits, including fewer trips to the field and less maintenance. It is more affordable than ever to adopt the EXO platform with these sondes. Take full advantage of the unmatched sensor and parameter selection, industry-leading anti-fouling, better data with Kor Software, and data visualization with HydroSphere

With the EXO-S series, you have even more reliable water quality data collection options. We're excited to expand the EXO family with these new sondes.
