There are notable non-electrical analog devices, such as some clocks (sundials, water clocks), the astrolabe, slide rules, the governor of a steam engine, the planimeter (a simple device that measures the surface area of a closed shape), Kelvin's mechanical tide predictor, acoustic rangefinders, servomechanisms (e.g. the thermostat), a simple mercury thermometer, a weighing scale, and the speedometer.

Non-electrical analog devices and electrical analog devices are the two categories of analog devices. Non-electrical analog devices include pendulums, analog watches, clocks, steam engine governors, and acoustic rangefinders. Analog televisions and computers are two examples of electrical analog devices.

Examples of analog devices Vinyl records and record players. CRT (Cathode Ray Tube) televisions and monitors. VCR (Video Cassette Recorder) players and tapes. Any clock without a digital display. Polaroid or film cameras. Traditional laser photocopiers. Digital, Electronics terms, PCM, Phone terms
