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.

GDX-FPH-BNC
Go Direct® Flat pH BNC Electrode
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. Technische Daten Messbereich: pH 0-14  Elektroden-Typ: Doppelter Anschluss, versiegelt, gelgefüllt, Ag/AgCl-Referenz, Polycarbonatgehäuse Membranform: Flachglas Pufferlösung: pH 4/KCl-Lösung (10 g KCl in 100 mL Puffer pH-4-Lösung) Temperaturbereich: 0- 100ºC (Messwerte nicht kompensiert) Aussendurchmesser des Fühlers: 12 mm Impedanz: ~20 kΩ bei 25ºC Ansprechzeit: 98% des Endwertes in 30 s bei 25ºC Konnektivität Kabellos: Bluetooth Drahtgebunden: USB

Electrode Support
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.

Nitrate Ion-Selective Electrode
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
