Le pH-mètre est constitué d’une électrode Ag-AgCl gel et de son amplificateur. Il peut être utilisé pour toutes les expériences de pH-métrie en chimie ou biologie. Il possède de la mémoire pour stocker des étalonnages qui seront automatiquement utilisés par le logiciel. Cela permet d'utiliser un étalonnage propre à chaque capteur sans avoir besoin de réétalonner à chaque utilisation. Un amplificateur d'électrode peut être acheté séparément pour connecter une autre électrode.

The Vernier Electrode Support connects to all standard ring-stand posts to keep sensors firmly in place during an experiment.
The 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.
The clamp end makes connecting to ring stands easy, accommodating post diameters between ~0.5 and 1 cm. The grooves on the Electrode Support to hold the wire leads for electroplating or electrolysis experiments.
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 ORP (Oxidation-Reduction Potential) Sensor measures the ability of a solution to act as an oxidizing or reducing agent. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.
Use the Go Direct ORP Sensor to measure the ability of a solution to act as an oxidizing agent and to quantify ion activity. This sensor measures the capacity of a solution to either release or accept electrons from chemical reactions.
This sensor is comprised of an ORP 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 pH Electrode, Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode.
The Go Direct ORP Sensor can be used in a variety of experiments:
Determine the equivalence point of an oxidation-reduction titration.

When Vernier introduced the new Drop Counter, they decided to include a Vernier Microstirrer to enhance stirring. Since then, they've had many requests to have this as a separate product.
The Microstirrer takes the place of the stirring bar that is typically used with a laboratory magnetic stirrer. The new Vernier Microstirrer easily attaches to the end of a pH Sensor, Conductivity Probe, Dissolved Oxygen Probe or Ion-Selective Electrode. When the magnetic stirrer plate (required, but not included) is turned on, its magnetic field turns the paddle wheel of the Microstirrer, resulting in enhanced stirring near the electrode tip. The Microstirrer works with any magnetic stirrer.
Ce sont les mêmes flacons que ceux dans lesquels sont livrés les capteurs de pH et d'ORP. Utilisez-les pour fabriquer des mini-béchers pour nos titrages à micro-échelle, ou simplement pour remplacer le flacon de stockage.
Chemistry with Vernier is the foundational chemistry book for high school and college courses.

The Go Direct Electrode Amplifier offers an affordable way to expand your experiment options. Its BNC connector provides the flexibility to attach and remove a Vernier electrode, such as the pH Electrode, Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode. You can explore pH one day and potassium concentrations the next.
Because the Go Direct Electrode Amplifier is compatible with third-party electrodes, students learn consistent calibration and handling techniques on one amplifier using one software program. When electrodes expire or become damaged you need only replace the electrode—lowering your overall equipment costs.

Quick-start guide
Der Go Direct Tris-kompatible pH-Sensor mit flacher Elektrode ist ein äußerst vielseitiger Sensor. Da die Glasmembran anstelle einer Kugel flach ist, ist sie haltbarer, leichter zu reinigen und ermöglicht flache Oberflächenmessungen oder kleinere Probengrößen. Er verfügt über eine versiegelte, gelgefüllte Doppelkontaktelektrode, die es kompatibel mit Tris-Puffern und Lösungen mit Proteinen oder Sulfiden macht. Die flache Glasform ermöglicht die Messung des pH-Wertes von pastosen und halbfesten Stoffen wie Lebensmittel oder Bodenschlämmen.
