Use the High Current Sensor in experiments that involve currents larger than 1 A, such as solar panels, hand generators, and other alternative energy projects. 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£103.00 ex VAT | £123.60 Inc VAT Add to basket
The Vernier Energy Sensor offers an easy way to quantify voltage, current, power, and energy output of small wind turbines and solar panels such as those used in our KidWind Experiment Kits. Simply connect a source such as a small wind turbine or solar panel to one side and a load such as the Variable Load or a resistor on the Vernier Resistor Board to the other side. The Energy Sensor measures the current and voltage of the system. Data-collection and analysis software, such as Logger Pro or LabQuest App can then calculate the power and energy output.£115.00 ex VAT | £138.00 Inc VAT Add to basket
The Barometer can be used to measure and monitor atmospheric pressure. It works well for conducting weather studies or experiments that involve pressures close to normal atmospheric pressure. It can also be used as an altimeter if you have a portable interface.£93.00 ex VAT | £111.60 Inc VAT Add to basket
Use the Drop Counter to perform accurate, automatic titrations. Record the number of drops or calibrate the drop size to record volume of titrant added during a titration. Logger Pro software can automatically convert the number of drops into volume. The Drop Counter can be used for conductimetric or potentiometric titrations using our Conductivity Probe, Ion-Selective Electrodes or any electrode with a 0 to 5 volt output.£129.00 ex VAT | £154.80 Inc VAT Add to basket
The CO2 Gas Sensor measures gaseous carbon dioxide levels in two selectable ranges of 0 to 10,000 ppm and 0 to 100,000 ppm (which covers human breath). Ideal for measuring changes in Carbon Dioxide levels during plant photosynthesis and respiration. You can easily monitor changes in CO2 levels occurring in respiration of organisms as small as crickets or beans! The CO2 Gas Sensor is easily calibrated using a calibration button. A chamber is included for running controlled experiments with small plants and animals. You may also wish to see our O2 Gas Sensor£350.00 ex VAT | £420.00 Inc VAT Add to basket
The Vernier Optical DO Probe uses luminescent technology to provide fast, easy, and accurate results, making it a terrific choice for biology, ecology, or environmental science courses. Students can measure dissolved oxygen concentration in surface water or to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment. Using Plug and play technology, no filling solution is required, no warm up time needed, no stirring and no calibration.£389.00 ex VAT | £466.80 Inc VAT Add to basket
The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle's law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.£116.00 ex VAT | £139.20 Inc VAT Add to basket
Use the Dual-Range Force Sensor in a wide variety of experiments including the study of friction, simple harmonic motion, impact in collisions, or centripetal force. The Dual-Range Force Sensor has two ranges: ±10N or ±50N. It can be easily mounted on a Vernier Dynamics Cart for use with the Vernier Dynamics System. Mount one on the New Centripetal Force Apparatus, on a ring stand or even as a replacement for a hand-held spring scale. Use it to study friction, simple harmonic motion, impact in collisions, or centripetal force.£142.00 ex VAT | £170.40 Inc VAT Add to basket
Use the Dissolved Oxygen Probe to determine the concentration of oxygen in aqueous solutions in the field or in the laboratory. The Dissolved Oxygen Probe is great for biology, chemistry, ecology, or integrated science courses. It can be used to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment.

Designed for much higher forces than the Dual-Range Force Sensor, the Force Plate can measure the forces developed during stepping, jumping, and other human-scale actions. For example, you can perform the following kinds of experiments:£376.00 ex VAT | £451.20 Inc VAT Add to basket
- Observe the change in normal force during a ride in a lift.
- Measure the impulse delivered by the floor during a jump.
- Measure the reaction force as a student leans against a wall.
The Anemometer can be used in a variety of experiments to measure wind speed. Can either be used hand held to measure wind speeds, or used with the accessory rod for static experiments such as in front of wind tunnels. The Vernier Anemometer is an impeller-type anemometer that measures wind speed in the range of 0.5 to 30 m/s (1 to 67 mph).£116.00 ex VAT | £139.20 Inc VAT Add to basket
