"SCIENTIFIC hatch"

Apparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate. Includes 3 steel balls. A micro-magnet holds the ball in its start position. Three contact pins under the release mechanism ensure that the start position of the ball can be reproduced and act as the contacts of a switch that opens when the ball is released, thus triggering the beginning of the timing measurement. When the ball strikes the contact plate at the bottom, the timer is stopped. The ball is also held firmly on the plate so that it does not bounce. The height through which the ball drops can be adjusted to a fraction of a millimeter and read off a scale on the column.

Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off, and power supplies for direct connection to light barriers. For event counting, a fixed counting period can be programmed in a range from 0.1ms to 99999s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.

Inexpensive, compact counter for measuring milliseconds (in conjunction with the free-fall apparatus 470162-756 ). Each count is started and stopped by a signal at the input sockets. The device is automatically reset to zero each time it is restarted. Includes plug-in power supply.

Sensor for triggering the digital counter in time measurements on moving objects. Suitable for opto electronic scanning of light and dark markings on moving objects or in conjunction with a reflecting foil to form a wide spaced obstruction sensor. The intensity of the laser beam is adjusted automatically according to the distance of the object. Includes reflecting foil, stand rod with screw thread, and connector lead with 8 pin miniDIN plugs.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.
