Bench Signal Generator provides two type of output waveforms sine, square with a continuous frequency range of 10Hz to 100kHz with four decade and Select able through the combination of set frequency control knob range selected by a rotary switch and maximum output amplitude of 5V (peak-to-peak). A set frequency. The front panel incorporates three safety sockets two for output signal and one for ground. The instrument has been designed with simplicity in mind to offer easy operability to the students. Features: Frequency ranges: 10-110Hz, 0.1-1.1 kHz, 1-11.1 Hz, 10-110kHz Maximum amplitude: 5V Waveforms Sine, square select able through a push switch Internal speaker select able through a push switch Frequency range coarse: (0.05, 0.5, 5, 50, 500, 5k) Hz Technical Specifications: Input voltage: 110V / 220V AC (Select able) Frequency: 50-60Hz Fuse (Primary): 0.5A Current rating: 100mA (max.) Power: 22W (max.)

"cOWBELL" This device is used to illustrate that pressure and temperature are related. When you press down quickly on the plunger, air is compressed inside the tube, igniting a cotton ball. The fire then instantly goes out, because all of the oxygen in the tube is exhausted. Can be used to illustrate the kindling point of a material. Built of rugged plastic, the chamber comes apart for easy cleaning.
