Barometer

This is basically three Low-g Accelerometers mounted at right angles and all placed in a small box. Can be used  for studying the complex motion of an amusement park ride, a bungee jumper, or simply a toss in the air. Range: -50 to +50 m/s2 Typical accuracy: ±0.1 m/s2

Data from the Calcium ISE can give a good indication of hardness of water (as Ca2+). The concentration of Calcium is also used as an endpoint indicator in EDTA-Ca/Mg hardwater titrations. The Calcium 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 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).  

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

This is a non-invasive sensor designed to measure human blood pressure. It measures systolic, diastolic and mean arterial pressure utilizing the oscillometric technique. Pulse rate is also reported.

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.

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

The Current Probe can be used to measure currents in low-voltage AC and DC circuits or electrochemistry experiments. The Current Probe measures DC and low-frequency AC currents up to 600 mA.
