Go Direct™ Electrode Amplifier

Info sui prodotti "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.

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. 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.   NO3-BTA 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.

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® Calcium Ion-Selective Electrode
I dati dell'Elettrodo Ion-Selettivo Go Direct Calcio possono fornire una buona indicazione della durezza dell'acqua (come Ca2+). La concentrazione di calcio viene utilizzata anche come indicatore finale nelle titolazioni EDTA-Ca/Mg di acqua dura. 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. L'elettrodo selettivo a ioni di calcio Go Direct ha uno stile combinato, non ricaricabile, pieno di gel. Come tutte le altre membrane in PVC ISE, la membrana sull'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. Batteria ricaricabile - Pronto quando sei La robusta batteria ricaricabile offre una lunga durata e un funzionamento sempre pronto quando si utilizza il sensore in modalità wireless. Monitora la durata della batteria direttamente dalla nostra pluripremiata app Vernier Graphical Analysis® e da LabQuest® 3. Se la batteria si scarica, basta collegare il sensore al cavo di ricarica e continuare a raccogliere, senza interruzioni o inconvenienti per voi o per i vostri studenti. Wireless o cablato: la flessibilità di scelta I sensori Go Direct si collegano direttamente al dispositivo mobile, al Chromebook™ o al computer utilizzando l'app Vernier Graphical Analysis®, senza necessità di acquistare apparecchiature o software aggiuntivi. I sensori Go Direct possono essere utilizzati via cavo tramite USB o wireless tramite la tecnologia wireless Bluetooth®, consentendo di scegliere la soluzione migliore per la vostra classe o laboratorio. Nota: Si consiglia di non acquistare i moduli di ricambio ISE troppo in anticipo rispetto al tempo di utilizzo previsto, in quanto la degradazione si verifica mentre sono immagazzinati sullo scaffale.Importante: Gli elettrodi ionoselettivi richiedono una buona tecnica chimica e un'attenta calibrazione per ottenere risultati accurati; non sono raccomandati per gli studenti delle scuole medie o elementari.
