Wireless Conductivity Sensor - PS-3210

PS3210_MAIN.jpg

Overview

Wirelessly measure both conductivity and dissolved solids. Highly accurate with a fast response time and featuring built-in temperature compensation.

The Wireless Conductivity Sensor measures the electrical conductivity of a water solution. Investigate the properties of solutions, perform conductometric titrations, model and measure water quality and more.

Typical Applications

Conductivity (the ability of a liquid to conduct electrical current) is one of the most common measurements in biological, chemical and environmental studies. This sensor measures the total concentration of ions in solution.

  • Water quality investigations
  • Studying the effects of pollution on water
  • Measuring Total Dissolved Solids (TDS)
  • Investigating solution properties
  • Performing condumetric titrations
  • Diffusion of ions through membranes

Special Features

  • Simplicity: just pair and go, no cables and adapters to manage
  • Variable sampling rate for capturing small fast changes or experiments that run for hours, days, or weeks.
  • Features convenient Bluetooth wireless connectivity and long-lasting coin cell battery
  • Logs conductivity data directly onto the sensor for long-term experiments. 
  • Dust, dirt and sand proof and water resistant (1 meter for 30 minutes)

Bluetooth 4 Connectivity

Required Software:

PASCO products that use Bluetooth® 4 technology - wireless sensors, smart carts, and the AirLink Interface - require the latest versions of our software. PASCO Capstone 1.9.0 is available for Mac and Windows. SPARKvue 2.7.0 is available for Mac, Windows, iOS, Android and Chromebooks.

Compatibility/System requirements

Any current model Mac, iPad, iPhone, Android tablet or Android phone will support direct connection to PASCO Bluetooth 4 devices.

Windows computers/tablets, Chromebooks and older Macs currently require the PS-3500 USB Bluetooth 4.0 Adapter to connect to PASCO’s Bluetooth 4 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.

How It Works

Conductance is the reciprocal of resistance. In this case the Wireless Conductivity Sensor determines the conductance of an aqueous solution by measuring the current flowing through the circuit created when a voltage is applied to a 2-cell electrode submerged in the solution.

The electrode cell is constructed from insulating material embedded with pieces of platinum that are placed at a fixed distance apart and serve as sensing elements.

Because conductivity is dependent on temperature, the Wireless Conductivity Sensor has built in temperature compensation.
