Conductivity Low Range Standard

For most applications, the Conductivity Probe does not need to be calibrated. If you choose to calibrate it, you will need accurate standard solutions. The 150 µ S/cm Standard is a good concentration to calibrate your Conductivity Probe in the low range (0 to 200 µ S/cm).

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.

Conductivity Medium Range Standard

For most applications, the Conductivity Probe does not need to be calibrated. If you choose to calibrate it, you will need accurate standard solutions. The 1413 µ S/cm Standard is a good concentration to calibrate your Conductivity Probe in the middle range (0 to 2000 µS/cm).

Microstirrer

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.

Go Direct™ Conductivity Probe

The Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform conductivity studies as a function of temperature. The Go Direct Conductivity Probe has a range of 0 to 20,000 μS/cm to provide optimal precision in any given range. An alternating current at its electrodes prevents polarization and electrolysis, reducing contamination of solutions. Its ABS-body graphite electrode resists the corrosion typical in metal electrodes. The Go Direct Conductivity Probe can be used in a variety of experiments: Demonstrate diffusion of ions through membranes. Investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Measure Total Dissolved Solids (TDS). Specifications: Range: 0 to 20,000 μS/cm (0 to 10,000 mg/L TDS) Temperature compensation: Automatic from 5 to 35°C, can be turned off Temperature range (can be placed in): 0 to 80°C Cell constant: 1.0 cm-1 Description: ABS body, parallel carbon (graphite) electrodes Dimensions: 12 mm OD and 120 mm length Connections: Wireless: Bluetooth Wired: USB Included Go Direct Conductivity Probe Micro USB Cable
