VERNIER GO DIRECT pH SENSOR
Vernier's Go Direct pH Sensor is a general purpose pH sensor used to monitor pH of aqueous solutions. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

The Vernier Go Direct pH Sensor is an important and versatile sensor for lab and field activities alike. It gives students the freedom to explore pH without the inconvenience of wires. No more spilled solutions or dangling wires. The Go Direct pH transmits live readings and captures data in real time.

The Go Direct pH Sensor can be used in a variety of experiments:
• Conduct acid-base titrations
• Monitor pH change during chemical reactions
• Test the pH and alkalinity of bodies of water
• Investigate household acids and bases

The sensor is comprised of a pH electrode connected to a Vernier Go Direct Electrode Amplifier via a BNC connector. This design enables you to use the Go Direct Electrode Amplifier with other Vernier electrodes, such as the Flat pH Electrode, ORP Electrode, ISE electrode or a third-party electrode.

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.

    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
    ACSBL021 - Biodiversity and the interconnec - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
    ACSBL029 - Biodiversity and the interconnec - 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 react - 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 react - 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 react - 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 reac - 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
    ACSCH101 - Equilibrium acids and redox reac - Chemical equilibrium systems - Acid­base indicators are weak acids or bases where the acidic form is of a different colour to the basic form
    ACSCH096 - Equilibrium acids and redox reac - Chemical equilibrium systems - Equilibrium position can be predicted qualitatively using equilibrium constants
    ACSCH091 - Equilibrium acids and redox reac - 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
    ACSCH100 - Equilibrium acids and redox reac - Chemical equilibrium systems - The pH scale is a logarithmic scale and the pH of a solution can be calculated from the concentration of hydrogen ions; Kw can be used to calculate the concentration of hydrogen ions from the concentration of hydroxide ions in a solution
    ACSCH099 - Equilibrium acids and redox reac - 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 reac - 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)
    ACSCH102 - Equilibrium acids and redox reac - 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
    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
