"Vernier Software & Technology"

Replacement package of 100 electrodes.

Measure electrical signals from muscle contractions, or make EKG tracings and surface EMG recordings.

Use the Turbidity sensor to measure the turbidity of freshwater or seawater samples. Its small, sleek design and simple setup make it easy to use at the collection site or when you return to the classroom.

Measure voltages in low voltage AC and DC circuits.

Use to study magnetic fields.

General-purpose pH Sensors can be used across disciplines, with applications in chemistry, biology, middle school science, and environmental science.

Measure concentration of ammonium in aqueous samples.

Measure the concentration of calcium in aqueous samples.

Measure the concentration of chloride in aqueous samples.

Measure the concentration of nitrate in aqueous samples.

Perform accurate, automatic titrations by counting drops of titrant.

Measure the concentration of ethanol in air above an aqueous sample.

The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.

Measure the concentration of potassium ions in aqueous solutions.

Easily quantify voltage, current, power, and energy output of small wind turbines and solar panels.

You can make fast, accurate measurements of dissolved oxygen concentration in water samples using our Dissolved Oxygen Sensor.

•Range of 0 to 14 mg/L (ppm) of dissolved oxygen.

•Built-in temperature compensation, which means you can do your calibrations in the lab, and then make measurements outdoors without having to recalibrate.

•Fast response time, reaching 95% of full reading in 30 seconds.

•Great for biology, chemistry, ecology, or integrated science courses.

Disposable caps with pre-fit membranes allow you to quickly and conveniently change membranes. An extra membrane cap is included with each probe.

Calibration is easy with this sensor. Simply place the electrode in the zero-oxygen solution provided with the probe for the 0% calibration point. For the 100% calibration point, place the electrode in air (or better yet, in water-saturated air, using the provided calibration bottle). The probe can be calibrated in any units you choose: % dissolved oxygen, mg/L, or ppm dissolved oxygen.

The DO-DIN and DO-BTA include the dissolved oxygen probe, zero-oxygen solution, extra membrane cap, a 100% calibration bottle, electrode filling solution, and a probe information booklet.
