Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source.

Noise generators and sources are used to produce noise outputs for testing radio frequency (RF) equipment

Venturi vacuum generators use the flow of motive fluid such as air, steam, or liquid to evacuate air

Vacuum pumps and vacuum generators provide sub-atmospheric pressure for a variety of industrial and scientific applications where a vacuum is required

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency.

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters.

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.
