Vernier Go Direct Glass-Body pH Sensor
Order code: GDX-GPH
VERNIER GO DIRECT GLASS BODY pH SENSOR
This high-quality glass body pH sensor can be used in non-aqueous solutions and solutions that contain organic solvents, strong acids or strong bases. The electrode features a sealed, gel-filled Ag-AgCl combination reference electrode and uses a BNC connector.
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™ 4 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™ 4 app. No additional equipment or software purchases are necessary. 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 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.

This product is used in teaching these Australian Curriculum codes:
ACSSU187 - Chemical Sciences - Chemical Reactions - Different types of chemical reactions are used to produce a range of products and can occur at different rates
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
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
ACSCH066 - Molecular interactions and reactions - Aqueous solutions and acidity - The pH scale is used to compare the levels of acidity or alkalinity of aqueous solutions; the pH is dependent on the concentration of hydrogen ions in the solution
ACSCH064 - Molecular interactions and reactions - Aqueous solutions and acidity - The presence of specific ions in solutions can be identified using analytical techniques based on chemical reactions, including precipitation and acidbase reactions
ACSCH097 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Acids are substances that can act as proton (hydrogen ion) donors and can be classified as monoprotic or polyprotic depending on the number of protons donated by each molecule of the acid
ACSCH096 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Equilibrium position can be predicted qualitatively using equilibrium constants
ACSCH091 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium
ACSCH099 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The relationship between acids and bases in equilibrium systems can be explained using the Brønsted Lowry model and represented using chemical equations that illustrate the transfer of hydrogen ions
ACSCH098 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The strength of acids is explained by the degree of ionisation at equilibrium in aqueous solution, which can be represented with chemical equations and equilibrium constants (Ka)
ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
ACSSU179 - Chemical Sciences - Chemical Reactions - Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer
