Wireless Optical Dissolved Oxygen Sensor - PS-3224

PS3224_MAIN.jpg

Overview

The Wireless Optical Dissolved Oxygen (ODO) Sensor is the perfect solution to monitor DO2 in the lab or the field. Optical technology is accurate, fast, and does not need flow or calibration.

The Wireless Optical DO Sensor actually contains three different probes. In addition to dissolved oxygen, there are also probes for atmospheric pressure and the water temperature.

A PASCO exclusive feature allows you to log data using the the sensor's built-in memory. After hours or even days, connect the sensor to your device and download the data. You can capture day/night nutrient cycles, changes in metabolic processes and more.

With the included cover, the sensor has a waterproof design and is submersible to 10 m.

No need for an interface.

All PASCO Wireless Sensors connect to computers, Chromebooks, and tablets, through Bluetooth 4. No other equipment required! Our software (SPARKvue or PASCO Capstone) allows students to see and analyze data in real time.

Long lasting, rechargeable battery

The Wireless Optical Dissolved Oxygen Sensor draws as little current as possible. This provides you with long battery life for lab activities. Our software also displays the battery level at all times. If it dips too low, connect the USB cable to charge while you collect data.

 

Typical Labs and Applications

  • Photosynthesis
  • Respiration
  • Fermentation
  • Monitoring water quality
  • Investigating watersheds
  • Measuring net primary productivity
  • Modeling ecosystems
  • Exploring how temperature affects the amount of dissolved oxygen

Bluetooth Low Energy Wireless Connectivity

Required Software:

PASCO products that use Bluetooth® Low Energy connectivity (wireless sensors, Smart Carts, and the AirLink) require the latest versions of our software.

PASCO Capstone is available for Mac and Windows. SPARKvue is available for Mac, Windows, iOS, Android and Chromebooks.

Additionally, the Wireless Motion Sensor and Wireless Smart Carts can be connected via Bluetooth and used with our MatchGraph app.

Compatibility/System Requirements

Any current model Chromebook, Mac, iPad, iPhone, Android tablet or phone will support direct connection to PASCO Bluetooth Low Energy devices. Also, any Windows 10 device with Creators Edition 1703 or later will support direct connection.

Chromebook users MUST have the latest firmware updates for ALL wireless sensors in order to use them without the USB Bluetooth Adapter. Full information.

All other Windows computers/tablets, older Macs, and Chromebooks without updated sensor firmware currently require the PS‑3500 USB Bluetooth Adapter to connect to PASCO’s Bluetooth Low Energy devices.

Full compatibility details are available, including compatibility information for older computing devices.

Datalogging

Independent datalogging 

Long term data collection directly on the sensor

In logging mode wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.

When the experiment is concluded, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.
