Info sui prodotti "Conductivity Probe"

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity.

The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.

Range:

Low Range: 0 to 200 μS/cm (0 to 100 mg/L TDS)
Mid Range: 0 to 2000 μS/cm (0 to 1000 mg/L TDS)
High Range: 0 to 20,000 μS/cm (0 to 10,000 mg/L TDS)

Typical Resolution:

Low Range: 0.1 μS/cm (0.05 mg/L TDS)
Mid Range: 1 μS/cm (0.5 mg/L TDS)
High Range 10 μS/cm (5 mg/L TDS)

Accuracy using factory calibration:

±8% of full-scale reading for low range
±3% of full-scale reading for mid range
±4% of full-scale reading for high range

Accuracy using custom calibration: ±2% of full-scale reading for each range

Response Time: 98% of full-scale reading in 5 seconds, 100% of full-scale in 15 seconds

Temperature Compensation: automatic from 5 to 35 °C

Temperature Range (can be placed in): 0 to 80 °C

Cell Constant: 1.0 cm^-1

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.

Water Quality with Vernier

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.

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.

Sensore di salinità

Permette di misurare facilmente e con grande accuratezza il contenuto totale dei sali disciolti in acqua. La salinità totale è un parametro molto importante nell’analisi delle acque di mare o degli estuari, dove l’acqua dolce dei fiumi si riversa nel mare. Il livello di salinità del mare è pressoché costante (circa 35 ppt o 35.000 mg/L), mentre negli estuari salmastri può essere compreso tra 1 e 10 ppt. La portata del sensore di salinità arriva fino a 50 ppt e ciò significa che è possibile effettuare misure in un ampia gamma di salinità diverse, dall’acqua dolce a quella di mare, fino ad arrivare anche allo studio di ambienti ipersalini.
