Solinst Eureka Water Quality Sondes

Established in 2002, Solinst Eureka is a global leader in designing and manufacturing multiparameter water quality sondes. We offer the largest selection of sensor technologies for multiprobes in the industry.

In addition to the latest technology for measuring common parameters such as temperature, pH, conductivity, dissolved oxygen, turbidity, and depth, Solinst Eureka provides specialty sensors including PAR (Photosynthetically Active Radiation), Total Dissolved Gas, as well as a long list of fluorometers.

The Trimeter and Manta Probes are multiparameter sondes designed for monitoring water quality in fresh, brackish, and marine environments. All sondes can be used for discrete sampling and profiling or self-powered datalogging. Real-time data is available through cloud-based software when connected to a telemetry station.

Users can operate the Trimeter and Manta Probes with various display options via a direct or Bluetooth® connection. Intuitive control software, compatible with Windows, iOS, and Android™, is included at no additional cost with every probe. Our sondes communicate via RS-232, SDI-12, or MODBUS, allowing flexibility in connecting to various dataloggers and PLCs.

Since Solinst Eureka offers the largest selection of water quality sensor technologies in the industry in addition to standard configurations, each probe may be customized for your specific application. Pick sensors to fully populate larger probes. Add a battery pack to convert a probe to a logging device.

All Trimeter and Manta Probes feature anti-corrosive housings and sensors, robust marine bulkhead connectors, and anti-fouling options. LED status indicators on each sonde provide essential diagnostic information. Each probe comes with an industry-leading 3 year warranty.

Water Quality Probe Sensors

The highest quality sensor technology, for unsurpassed accuracy and reliability.

Temperature

Solinst Eureka instruments measure temperature with a thermistor – a small semiconductor whose electrical resistance varies predictably with temperature.

pH

pH is measured with a pH sensor and reference electrode. The pH sensor is a small, glass bulb filled with an electrolyte of known pH.

Turbidity

Turbidity is an indication of the amount of light that will pass through a column of water. Clear waters have low turbidity; waters with high suspended solids have high turbidities.

Dissolved Oxygen

Solinst Eureka optical DO sensors use blue light that is directed to an oxygen-active compound which has been stabilized in an oxygen-permeable polymer. The blue light causes the oxygen-active compound to fluoresce

Total Dissolved Gas

Solinst Eureka’s TDG sensor is similar to others in the water quality monitoring industry. However, Solinst Eureka is one of the few multiprobe manufacturers that offers a TDG sensor that may also be installed on a multiprobe along with additional sensors, such as dissolved oxygen, turbidity, pH and conductivity.

Conductivity

The easy to clean, flow-through design of the Solinst Eureka conductivity sensor is superior to those with electrodes partially hidden in a recess.

Pressure

An absolute depth sensor (pressure transducer), or vented depth sensor, may be added to any Manta or Trimeter multiprobe, along with other sensors.

CO2

Solinst Eureka’s CO₂ (Carbon Dioxide) sensors are the best of their kind for portable, water-quality instruments. Although it is a large sensor, it may be installed in the MantaPlus 40 multiprobe along with other sensors such as dissolved oxygen, pH and conductivity.

ISE Ion-Selective Electrodes

Solinst Eureka’s flowing-junction reference electrode provides better long-term stability than gelled-electrolyte reference electrode. The reference electrode is easily rejuvenated by unscrewing the tip, filling the sensor with fresh electrolyte, and screwing the tip back into place.

PAR

Most PAR (photosynthetically active radiation) sensors when coupled with multiparameter water quality sondes need additional mounting brackets, or cages, to hold the PAR sensor in place. This is not necessary for Solinst Eureka’s PAR sensors, as they are connected to the body of the sonde. For convenience, Solinst Eureka’s PAR sensors may be removed and replaced with a water-proof plug when not in use.

What our Clients Say

|

Associate Professor

“Your training and other technical support during your visit were very informative. The way you taught was very effective and greatly helped us understand not only how the instruments work but also how calibration and field maintenance should be done appropriately.  The help you provided went way beyond our expectation. We were really impressed by the quality of products and custom service provided by Eureka company.”

State University

Aquatic Biologist

“You guys will be happy to know that a Manta was deployed for a full month and came back with really good data (collected Winklers 2x/week and then compared to a tank in house post deployment). I am impressed! I expect any LDO probe to outperform a Clark cell probe, but the heavy sediment load at the deployment location seems to show that your DO probe is more robust and/or that your wiper design is superior to the sponge wiper setup on other LDO probe sondes.”

Water Management District

Scientist

“I cannot say enough good things about the initial set up of the sonde. The software was super easy to navigate. I did a demo on a Seabird instrument before and it took me a day to learn just the software.”

Environmental Monitoring

Environmental Researcher

“It was 13 degrees Fahrenheit when we left in the morning and 20 degrees at 1 PM when we returned. I have been very happy with the equipment so far. Our equipment is used in harsh conditions at times, and it is used by different people at times. Thank you for all your assistance and quick response to my problems.”

State Agency

Assistant Professor

“We would like to attest our fullest satisfaction with the probes, particularly with the copper mesh guards, which we believe are crucial to near perfect condition our sensor are after retrieved 30 days later in highly productive coastal waters. The probes are easy to calibrate, and the descriptions provided are straightforward and work well...All in all, thumbs up, Eureka!”

Dept of Marine Sciences

Environmental Scientist

Thank you for all your help and support.  Eureka and you, are great to work with and I love your product !”

State Government

Marine Aquatic Scientist

“Our Manta is currently on a three-week deployment and working flawlessly. I think we’ll eventually be interested in more units, but for now our two older probes from one of your competitors, are limping along.”

Aquatic Ecologist

“Just got back to the US after a very successful field season. The Mantas worked great. Thanks again for all your help this summer. It was quite a field season. A hippo or large nile crocodile bit one of the Manta2s....and it survived The outer PVC housing was destroyed but the Manta2 was essentially untouched.”

Aquatic Scientist

The Anti-fouling kit with the replaceable copper gauze has helped improve my turbidity data significantly. In highly productive streams and/or rivers, my Manta system would often times end up with loose vegetation wrapped around the turbidity sensor wiper. This would give me days or weeks worth of bad data until I could go out and remove the offending weeds . After installing the copper gauze, I have consistently more accurate turbidity data that requires removing far fewer false data points in post processing”

Laboratory Analyst

“Again, I want to thank you for an AWESOME product, and great customer service!  I am impressed with your company’s product, service, and the software’s user friendly/customizability.”

Lead Scientist

“I wanted you to know that I just returned from an extensive sea trial of the Manta in my mapping setup, and it performed flawlessly.  I ran it alongside a suite of fluorometers, along with a water probe from one of your competitor’s (which is what I will replace with the Manta).”

Associate Professor

...“just came back from a sampling trip and have been using the Manta. It’s working out really well. I would be happy to talk to whoever is considering buying one.”

Environmental Consultant

...“My business partner was "brought up with the other instrumentation guys" but I've recently been able to convince him to switch over to Eureka. The reasons were simple...quality of the instrumentation and excellence service.”

Prof Anthony (Ticky) Forbes Director and Lead Scientist

We have used our Manta multi-probe for over 10 years with great success and reliability in many South African east coast estuaries.  We have tried some other brands but found the response time in the Manta to be far more rapid.”
