Force gauges, set in case
Force gauges, set in caseNine different precision dynamometers/force gauges of types FR-103800 – FR-103880 with ranges 0.1-0.2-1-2-5-10-20-50-100 Newton.
Supplied in a handy, foam-lined, partitioned case.
Case size: 327 x 275 x 55 mm.
Free-fall apparatus
Free-fall apparatusThis experimental equipment can be used for experiments with the movement of objects, and it can thus be used to determine the gravitational acceleration g based on the fall time and the fall length, as the following relationship applies:
where h is the drop height.h
Friction block, area
Friction block, areaBlock with a hook for demonstrating the relationship between friction and different surfaces. Two versions available. Area: Two different surface contact areas.
Friction block, roughness
Friction block, roughnessRoughness: Four different surface materials: rubber, felt, sandpaper and wood.
Fuel cell set, Dr FuelCell
Fuel cell set, Dr FuelCellComplete energy kit containing various sources for the production of green energy.
The set includes a combustion cell, a solar cell for power supply for the electrolysis apparatus, and a measuring instrument for measuring the total amount of energy. In addition, data can be transferred to a PC for further analysis. Software is included on CD or as a download on Horison’s website. A guide with experimental examples is also included.
Fuel cell vehicle, Hydrocar
Fuel cell vehicle, HydrocarExperiments can be set up with this hydrogen car. where it is shown that electrolysis with power from the solar panel can be used to produce the hydrogen that the car is powered by using hydrogen combustion in the fuel cell.
Fuel cell, dismantlable
Fuel cell, dismantlableThis fuel cell can be dismantled, so its constituent parts can be studied.
Fuel cell, ethanol
Fuel cell, ethanolThis fuel cell kit with propeller contains a fuel cell that produces power from an ethanol solution of up to 15%. This makes it possible to investigate how the effect from the fuel cell changes with different ethanol solutions. There is also the option of making power outlets for other power consumption, e.g. bulbs or motor. A pH paper is included to examine changes in the pH value in the residual product from the energy process with the ethanol used.
Function generator
Function generatorThis function generator is developed and produced by Frederiksen Scientific and is suitable for, for example, experiments with standing waves or for studying sound waves at different frequencies. The generator can run through frequencies in intervals of ten decades from 0.001 Hz to 10.00 MHz with a tolerance of just 0.005%.

Galvanometer
GalvanometerRugged, user-friendly instrument that is easy for the students to read.
Gas model with piston
Gas model with pistonIn conjunction with 218500 Electromagnetic vibrator, the steel balls illustrate molecules in different states. The steel balls in motion represent gas molecules which lift a plastic piston due to repeated collisions. The model is supplied with piston, balls and a support for placing the apparatus on an overhead projector. Can be used to demonstrate gas states, Brownian motion and the boiling of a liquid. Excludes Electromagnetic vibrator.

Gasoline cannon with lighter
Gasoline cannon with lighterConsists of a plexiglas tube with a piezoelectric igniter (appearance may vary) fitted in a rubber stopper.
Gaussian Gun
Gaussian GunThis Gaussian gun can be used for experiments within dynamics, where the conversion of potential energy into kinetic energy must be investigated.
Gear motor with winding shaft
Gear motor with winding shaftThis gear motor is used together with the conical pendulum FR-207010 and is driven by an adjustable DC motor (max. 12 V). It has a built-in 21:1 gearing that ensures a stable and slow walk. The motor is equipped with a removable winding shaft. Thus, it can also be used via a thread to create a slow and linear movement.
