Water chemistry, measured where it’s happening. Our lab-on-chip sensors bring laboratory-level sensitivity into the field, with high-frequency measurements. Got a water monitoring project? Let’s talk. clearwatersensors.com #WaterQuality

What does ‘lab-on-chip’ mean? It miniaturises wet-chemical analysis so measurements can happen automatically, in situ - combining microfluidics, reagents and calibration in a compact sensor platform. clearwatersensors.com/techno… #LabOnChip #Sensors #WaterMonitoring

PFAS were detected in 61% of 152 freshwater samples analysed for the Great UK WaterBlitz. At ClearWater Sensors, we're developing an in situ PFAS sensor to help capture changes in contamination between sampling events. Read the @Earthwatch_Eur report: earthwatch.org.uk/report/gre…

River water chemistry rarely tells a simple story. Our work in the Teifi catchment found higher phosphate levels in some rural tributaries than in the main river. Why monitoring across a catchment matters... clearwatersensors.com/case-s… #WaterQuality

Lab-grade phosphate analysis, in the water. Sensitive wet chemistry, onboard calibration and high-resolution data from rivers to the deep ocean. Built for long-term autonomous monitoring. clearwatersensors.com/phosph… #Phosphate #WaterQuality

High-frequency monitoring in the Teifi catchment revealed phosphate levels that periodic sampling could miss. Sensor data and citizen science are helping build a clearer picture of water quality. Want to know more? Visit clearwatersensors.com #Phosphate #WaterSensors

Meet our nitrate sensor: a miniaturised lab-on-chip analyser for nitrate and nitrite measurements in freshwater and seawater, with onboard calibration and deployment to depths of 6,000 m. Planning a monitoring project? We’d love to hear about it. #Nitrate #WaterQuality #LabOnChip

What happens between water samples? Short-lived peaks can pass unnoticed. ClearWater Sensors help reveal changes that periodic sampling can miss. What are you struggling to capture? Talk to us about your monitoring challenge. clearwatersensors.com/contac… #WaterQuality #Sensors

Great to see the new GEORGE project online training platform go live! We're pleased to have contributed a module. A fantastic free resource for anyone working with ocean observing technologies. #OceanObserving #MarineTechnology #GEORGEProject
📣 The GEORGE project has launched a brand new online training platform for autonomous marine observing technologies. The training is open for all, but will serve especially marine RI professionals working with autonomous observing technologies. 💻 👉: ow.ly/4I4b50ZS63U

Yesterday we checked in on this ClearWater Sensors phosphate sensor, which is collecting a fantastic dataset at this beautiful site in Wales. There are now four phosphate sensors installed at different sites along this river.

We pulled the sensor out of its deployment tube so that we could change its inlet filter. This was a precautionary measure, as it hadn't blocked. Its a 0.45 micron filter, but the sensor uses tiny sample volumes so this filter can last for a while.

We then re-deployed the sensor and went on our way. A telemetry unit (located in the black box) is sending us the phosphate readings in real time.

A silicate sensor, a phosphate sensor and a spare reagent canister about to be shipped to customers in Germany and the USA. All part of a busy week working at ClearWater Sensors. Do get in touch if you are interested in in situ nutrient monitoring sensors and services.

Singapore, South Korea & now Japan better understanding Phosphate, Silicate, Nitrate and pH data in real time. Thank you CT&C for joining our community with your commitment to solving environmental issues in water.

Two more of our sensors (phosphate on the left, nitrate on the right) about to be deployed for a customer in a Welsh river. Great data coming back over telemetry from this remote site.

@CWSensors is proud to be using and developing our pH sensors to help the global effort to measure and manage the ocean carbonate (carbon dioxide) system in the @GeorgeEUproject
Further development of new sensors and platforms for measuring CO2 in the ocean is urgently needed to understand ocean processes and monitor anthropogenic changes to ocean biogeochemistry. Read how GEORGE contributes: bit.ly/3vPaye9
