Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with the versatile multiparameter EXO1 sonde. Ideal for estuarine, surface water or ground water applications.
Instrument Only. Cables, probes/sensors, and accessories sold separately - please see the "Accessories" tab for details.
The EXO 1 is a muliparameter instrument that collects data with up to four user-replaceable sensors and an integral pressure transducer for depth.
Extremely versatile instrument, allowing the user to automatically configure a sonde with different sensor for different applications in minutes
Smart Ports: Each sensor port on the sonde accepts any EXO water quality sensor and automatically recognizes it. Sensors are user-replaceable and made from rugged titanium housing.
Tested in a variety of rigorous field conditions as well as lab conditions to ensure accuracy and response times
No matter which EXO sensors users select, other features of the sensors' design make them rugged and durable:

**Specifications indicate typical performance and are subject to change. All sensors have a depth rating to 250 m (820 ft), except shallow and medium depth sensors, ammonium, chloride, and nitrate. Accuracy specification is attained immediately following calibration under controlled and stable environmental conditions. Performance in the natural environment may vary from quoted specification.
