Sensors for collecting water quality data

PASCO offers the convenient Water Quality MultiMeasure Sensor, combining four common water quality sensors into one. Now measure temperature, pH, conductivity, and dissolved oxygen -- all with just one sensor box. Field measurement made simpler -- why carry more?

Sensor-based measurements:

We offer more than 60 PASPORT Sensors, including a full suite of water quality sensors to measure all the following:

Conductivity
Dissolved Oxygen
Temperature
pH

Turbidity
Flow Rate
Thermocline

Chemical water quality analysis

With PASCO, it's a snap -- measure ion concentrations out in the field and avoid chemical contact. You get results in just minutes -- no more extensive preparation and mixing. These self-contained tests are the perfect answer for simpler, more accurate, and safer chemical analysis.

Chemical analysis:

Use PASCO's ezSample Water Quality Test Kits for simplified chemical testing of these water quality parameters:

Nitrate
Phosphate
Ammonia
Sulfate
Iron

Fluoride
Chlorine
Total Hardness
Carbon Dioxide
Alkalinity

Map & Understand

Put your water quality data in context

Give your students the full experience -- equip them to map their water quality data for a complete contextual understanding. PASCO makes it easy. When you use the PASPORT GPS Position Sensor, all the data you collect is automatically paired to its geographic position.

Open your data in My World GIS and you can visualize your collected data on topographic maps, aerial photos, and more. Even add annotations -- including videos and photographs -- of your local environment, easily accessible via clickable hotspots.

Why try to analyze your water quality data in a table? Map it and see how the data corresponds to many other environmental features, another student's dataset, and much more.

What's happening here? Nitrate data was collected at several locations along a stream running through a housing development. When mapped in My World GIS, students see that the value downstream, below the housing development, is much higher. Students can discuss -- or even investigate -- potential causes. Enlarge image
