This wire has a memory enabling it to be shaped when cooled and then snapping back into its original shape when warmed. Demonstrates solid state phase changes as crystalline structure changes. Supplied with explanation and possible uses. 75mm long with safety ends - care must be taken as it re-forms with surprising force.

Electromagnetic Field Radiation meters for science experiments or for safety checks of appliances like microwave ovens, computers, televisions, transmission towers, power lines etc. Two models are available, one has the sensor on a 900mm long cable making it easier to monitor awkward areas, the other has the sensor incorporated in the body of the meter. Both meters have the same three measuring ranges:
20µT to 200mG, accuracy +/- 4% plus 3 digits, resolution 0.01µT (T=Tesla, G= Gauss)
200µT to 2,000mG, accuracy +/- 5% + 3 digits resolution 0.1µT
2,000µT to 20,000mG accuracy +/-10% + 5 digits resolution 1µT
Operating bandwidth: 30 to 300 Hz. Supplied with 9V battery, Calibration Certificate and vinyl carry-case.
