Electrode Support
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.

Go Direct® Morsetto del sensore
Il morsetto Go Direct Sensor si fissa saldamente a un sensore Go Direct a bacchetta e il cordino incluso funziona come una cinghia per prevenire cadute accidentali durante le indagini sul campo. Rilassati sapendo che gli studenti non faranno cadere i sensori mentre raccolgono campioni d'acqua sul posto con la sonda di ossigeno disciolto ottico Go Direct o sospendono una sonda di temperatura Go Direct su un albero per rilevare la temperatura atmosferica. La pinza per sensori Go Direct non può essere utilizzata con il cavo USB collegato. Questo accessorio non rende un sensore impermeabile, né deve essere utilizzato per far ruotare un sensore lungo un percorso circolare.

Go Direct™ Electrode Amplifier
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.   Rechargeable Battery—Ready When You Are The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our free Graphical Analysis™ 4 app or LabQuest 2 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 sensors connect directly to your mobile device, Chromebook™, or computer using our 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® wireless technology, allowing you to choose the solution best for your classroom or laboratory. Specifications Units: pH or mV Input range (mV): ±1000 mV Input range (pH): 0 to 14 pH Accuracy with new electrode (mV): ±20 mV Accuracy with new electrode (pH): ±0.2 Connections: Wireless: Bluetooth Wired: USB

Calcium Ion-Selective Electrode
Data from the Calcium ISE can give a good indication of hardness of water (as Ca2+). The concentration of Calcium is also used as an endpoint indicator in EDTA-Ca/Mg hardwater titrations. The Calcium ISE has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module, and replace it with a new one. Note: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use as degradation occurs while they are stored on the shelf.   Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.   CA-BTA User manual

Potassium Ion-Selective Electrode
The Potassium Ion-Selective Electrode can be used to measure the concentration of potassium (K+) ions in aqueous solutions. The Potassium Ion-Selective Electrode makes the measure of potassium ions portable. When used with a Vernier LabQuest 2, the Potassium ISE can be used to take readings in the field – at lakes or streams. This sensor is easier to set up and use than other methods of measuring potassium ion concentration in aqueous solutions. Because it is a stick-style sensor, its use is similar to using a conductivity probe or a pH sensor in a laboratory setting or in the field. Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results. They are not recommended for middle school or elementary students. User manual

Go Direct® Elettrodo ione-selettivo di potassio
Utilizzare l'elettrodo Go Direct Potassium Ion-Selective per misurare i livelli di ioni di potassio in modalità wireless. Il versatile connettore BNC consente agli studenti di sostituire facilmente l'elettrodo quando scade o si danneggia. Basta sostituire l'elettrodo e non l'intero sensore, riducendo così i costi complessivi dell'attrezzatura. Il Go Direct Potassium Ion-Selective Electrode ha uno stile combinato, non ricaricabile, pieno di gel. Come tutte le altre membrane in PVC ISE, la membrana su ISE ha un'aspettativa di vita limitata. Tuttavia, il modulo sostituibile di ISE consente di scartare semplicemente il modulo di membrana usato e sostituirlo con uno nuovo.

Chloride Ion-Selective Electrode
The concentration of the Chloride ion gives a quick measurement of salinity of water samples. Use the Chloride ISE to measure chloride levels in ocean saltwater or salt in food samples. The Chloride ISE has a combination-style, non-refillable, gel-filled electrode. Unlike other ISEs available from Vernier, the Chloride ISE has a solid-state membrane that does not need to be replaced.   Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.   CL-BTA User manual

Nitrate Ion-Selective Electrode
Nitrate concentration, which can be increased by acidic rainfall, fertilizer runoff from fields, and plant or animal decay or waste, is an important parameter in nearly all water quality studies. Use the Nitrate ISE to determine the concentration of the nitrate ion in a water sample. The Nitrate ISE has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module, and replace it with a new one.
