VERNIER GO DIRECT CONDUCTIVITY PROBE
Vernier's Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.
The Vernier Go Direct Conductivity Probe features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform conductivity studies as a function of temperature.
The range of 0 to 20,000μS/cm provides optimal precision in any given range. An alternating current at its electrodes prevents polarization and electrolysis, reducing contamination of solutions. Its ABS-body graphite electrode resists the corrosion typical in metal electrodes.
Use this probe in a variety of experiments:
• Demonstrate diffusion of ions through membranes.
• Investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions.
• Measure Total Dissolved Solids (TDS).
Rechargeable Battery — Ready When You Are
The Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ app Should the battery run low simply connect the sensor to the charging cable and keep on collecting — no interruptions or inconvenience to you or your students.
Wired or Wireless — The Flexibility to Choose
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ app. No additional equipment or software purchases are necessary. Vernier Go Direct sensors can be used wired via USB or wirelessly via Bluetooth allowing you to choose the solution best for your classroom or laboratory.
Vernier Graphical Analysis™ Pro is an annual subscription upgrade that includes all the features of the free Vernier Graphical Analysis app, plus enhanced functions for more advanced analysis. Its illustrative experiment videos and interactive graphing capabilities inspire students to explore crucial scientific concepts and analyze data in new complex and insightful ways.
Vernier Graphical Analysis™ Pro is compatible with most Vernier sensors and multiple operating systems and devices.

ACSBL019 - Biodiversity and the interconnectedness of life - Describing biodiversity - Ecosystems are diverse, composed of varied habitats and can be described in terms of their component species, species interactions and the abiotic factors that make up the environment
ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
ACSBL047 - Cells and multicellular organism - Cells as the basis of life - Factors that affect exchange of materials across membranes include the surface-area-to-volume ratio of the cell, concentration gradients, and the physical and chemical nature of the materials being exchanged
ACSBL046 - Cells and multicellular organism - Cells as the basis of life - Movement of materials across membranes occurs via diffusion, osmosis, active transport and/or endocytosis
ACSBL045 - Cells and multicellular organism - Cells as the basis of life - The cell membrane separates the cell from its surroundings and controls the exchange of materials, including gases, nutrients and wastes, between the cell and its environment
ACSCH063 - Molecular interactions and reactions - Aqueous solutions and acidity - The concentration of a solution is defined as the amount of solute divided by the amount of solution; this can be represented in a variety of ways including by the number of moles of the solute per litre of solution (mol L1) and the mass of the solute pe
ACSCH065 - Molecular interactions and reactions - Aqueous solutions and acidity - The solubility of substances in water, including ionic and molecular substances, can be explained by the intermolecular forces between species in the substances and water molecules, and is affected by changes in temperature
ACSCH061 - Molecular interactions and reactions - Aqueous solutions and acidity - Water is a key substance in a range of chemical systems because of its unique properties, including its boiling point, density in solid and liquid phases, surface tension, and ability to act as a solvent
ACSCH102 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Volumetric analysis methods involving acidbase reactions rely on the identification of an equivalence point by measuring the associated change in pH, using chemical indicators or pH meters, to reveal an observable end point
ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
