Go Direct® Ammonium Ion-Selective Electrode

Our Electrode Support is a great complement to the Vernier Stir Station, as well as a perfect holder for many sensors. It is built to connect to all standard ring-stand posts; its large-handled locking nut keeps your sensors firmly in place. The larger opening (13 mm in diameter) is perfect for our pH, ISE, Conductivity and ORP sensors. The smaller opening (5 mm) is designed to hold our Stainless Steel Temperature Probe or the Vernier Go!Temp. What's included Electrode Support User Manual - ESUP

The High and Low ISE standards are used to calibrate our Ammonium Ion-Selective Electrodes. User Manual - NH4-LST

Water Quality with Vernier has 18 water quality tests, including pH, total dissolved solids, dissolved oxygen, BOD, flow rate, turbidity, nitrates, and phosphates. All nine tests in the Water Quality Index (WQI) are supported. A comprehensive introduction is included for each test, providing important background information for the students. The printed version includes access to the electronic edition online.  

The Go Direct® Charge Station is the perfect solution for charging your Go Direct Sensors. Each charge station has sixteen charging ports—eight USB and eight wand-style sensor ports. LED lights on the Go Direct sensors will show charging status. The Go Direct Charge Station is also compatible with Go Wireless devices. USB cables not included. User Manual - GDX-CRG-EURO

With Graphical Analysis Pro, students can visualize scientific data collected from Vernier sensors—boosting their understanding and engagement using rich, real–time graphs. This-easy-to-use-app works on operating systems commonly found in the classroom. Graphical Analysis Pro also includes crucial features that promote three-dimensional learning, critical thinking, student collaboration, asynchronous instruction, and deeper analysis of experiment phenomena. Review the comparison table below to see what Graphical Analysis Pro can add to your classroom.  Data Collection Collect experiment data from multiple sensors simultaneously using a multiple-channel interface, such as LabQuest Stream® or multiple Go Direct® sensors. Data Visualization Help your students visualize experiment data—and increase comprehension and retention—with richly detailed, customizable graphing.         Graphical Analysis Pro Remote EducationData Sharing Boost your students’ understanding of complex science concepts with real-time data sharing. Seeing experiment data collected right before their eyes helps students connect abstract ideas to the real world. Videos Synced with Data Customize instruction and learning using your experiment videos synced with data. Your students can even upload and share their own videos.   Sample Experiments Access dozens of experiment videos synced with real data to support both remote and in-person learning. These sample experiments help your students experience an experiment, even when lab equipment is unavailable. You can also use sample experiments for pre-labs and differentiation of instruction. Advanced Data Analysis Give your students more options for deeper analysis with user-defined curve fits and calculated columns. These features provide equation and expression customizations directly in the app for immediate analysis.

This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of an Ammonium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.
