Product Description
£389.00 ex VAT | £466.80 Inc VAT
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 Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments, and as such eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in Chemistry. It is capable of delivering 0.6 A at 5VDC Use the Constant Current System to explore Faraday's law and determine Avogadro's Number. Note: It can only be used in conjunction with its own built-in power supply. It cannot be used to measure the current of a circuit using a different power supply.

The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound. Used with Vernier technology, students no longer have to determine the optical maximum with their eye but have a graph that shows a clear change in the light's polarization.

Our Hand-Grip Heart Rate Monitor is ideal for determining a person's heart rate while mobile or stationary. With this sensor, heart rate can be monitored during, or after, exercise. The sensor consists of wireless hand grips and a receiver module that plugs into any of our data-collection devices. The hand grips sense the electrical signals generated by the heart. For each pulse detected, a signal is transmitted to the receiver module, and the individual's pulse rate is calculated. Do you need an interface? Why not go for our Heart Rate Human Physiology Kit?

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.
