Go Direct® pH Sensor

DescriptionDescriptionSpecificationExperimentsRequirementsWhat's IncludedAccessoriesDescriptionThe 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.This sensor is comprised of a pH electrode connected to a 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 Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our 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 Our Go Direct™ pH Sensor connects directly to your mobile device, Chromebook, or computer using our free Graphical Analysis™ 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.SpecificationpH range: 0-14Accuracy with new electrode (pH): ±0.2Type: Sealed, gel-filled, polycarbonate body, Ag/AgCl reference, single junctionShaft diameter: 12mm ODStorage solution: pH-4/KCI solution (10g KCI in 100ml buffer pH-4 solution)Connections are either wireless via Bluetooth or wired via USB.ExperimentsInvestigating Chemistry through InquiryLong Term Water MonitoringAcid-Base Properties of Household ProductsThe Effect of Acid Deposition on Aqueous SystemsAcid-Base TitrationsBaking Soda and Vinegar Investigations RevisitedPhysical Science with VernierHousehold Acids and BasesAcid RainMiddle School Science with VernierSoil StudyA Water Field StudyChemistry with VernierHousehold Acids and BasesAcid RainTitration Curves of Strong and Weak Acids and BasesAcid-Base TitrationTitration of a Diprotic Acid: Identifying an UnknownAcid Dissociation Constant, KaTime-Release Vitamin C TabletsThe Buffer in LemonadeDetermining the Phosphoric Acid Content in Soft DrinksMicroscale Acid-Base TitrationAdvanced Chemistry with VernierStandardising a Solution of Sodium HydroxideAcid-Base TitrationInvestigating IndicatorsSeparation and Qualitative Analysis of CationsSeparation and Qualitative Analysis of AnionsBuffersDetermining the Ksp of Calcium HydroxideDetermining Ka by the Half-Titration of a Weak AcidRequirements LabQuestInterfaceLabQuest AppLabQuest 3Full SupportLabQuest 2 (Discontinued)Full Support 1Vernier LabQuest (Discontinued)Incompatible COMPATIBILITY NOTES 1.Wireless connection of this sensor to a LabQuest 2 requires a Go Direct Bluetooth Adapter when used with some older LabQuest 2 models.
