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?£155.00 ex VAT | £186.00 Inc VAT Add to basket
The Vernier Go Wireless Heart Rate is ideal for continuously monitoring heart rate before, during, and after exercise or while a person is stationary. Data are wirelessly transmitted to iPad, LabQuest 2, or other mobile devices that are Bluetooth® Smart Ready. It is simple and easy to use, displays live heart rate readouts before data collection, and is easy to clean and share between students.£116.00 ex VAT | £139.20 Inc VAT Add to basket
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.£90.00 ex VAT | £108.00 Inc VAT Add to basket
The EKG Sensor measures electrical signals produced during muscle contractions, and can be used to make standard 3-lead EKG tracings or surface EMG recordings. The EKG Sensor measures electrical signals produced by the heart. It uses three disposable electrodes. An EKG graph is displayed, demonstrating to students the contraction and repolarization of the heart's chambers. A package of 100 disposable electrodes is included with the sensor.£200.00 ex VAT | £240.00 Inc VAT Add to basket
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 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
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
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.£114.00 ex VAT | £136.80 Inc VAT Add to basket
Our strain-gauge based isometric Hand Dynamometer can be used to measure grip strength, pinch strength, and to perform muscle fatigue studies. Use the hand dynamometer with other sensors (e.g., EKG Sensor) to study muscular health and activity£140.00 ex VAT | £168.00 Inc VAT Add to basket
The Vernier Go Wireless Exercise Heart Rate is an excellent hands-free option for continuously monitoring heart rate before, during, and after exercise or while a person is stationary. Using the chest strap, data are wirelessly transmitted to iPad, LabQuest 2, or other mobile devices that are Bluetooth® Smart Ready. It displays live heart readouts before data collection,and is ideal for running, cycling and other physical activities. For an option to monitor heart rate with hands, please consider the Go Wireless Heart Rate.£103.00 ex VAT | £123.60 Inc VAT Add to basket
The Instrumentation Amplifier monitors voltages from 20 mV to 1 V (DC or AC). It has several switch settings to allow you to select the best gain and includes auto-ID functionality for each of the six ranges. Input bandwidth of 10 kHz allows the capture of higher frequency signals. It is typically used to amplify the chart recorder or analog output of any instrument, such as a third-party gas chromatograph.£103.00 ex VAT | £123.60 Inc VAT Add to basket
The Digital Control Unit (DCU), combined with features in Logger Pro, makes control of electrical devices, such as buzzers, lights, motors, pumps, and relays, both straightforward and flexible.
