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

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.

The Goniometer measures the angle of a joint, such as the knee or elbow. Use it to analyze the range of motion of a limb during different types of physical activity.

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.  

Ideal for most acceleration experiments. Use it for studying the one-dimensional motion of a car (real and toy), lift, pendulum bob, or amusement park ride.

• Range: -50 to +50 m/s2
• Typical accuracy: ±0.1 m/s

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.

Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH3 to NH4+. The Ammonium 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.

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.
