Analogue (Dial) Control

image of a control dial off an ultrasonic cleaner

Manual dial adjustment ultrasonic cleaners. These entry level models have a simple dial to set the cleaning time (0-20 minutes) and operating temperature (20 - 80 degrees C). There is no LED display. The standard of cleaning is exactly the same with the digital models. The only difference is the maximum time allowed with the dial operation timer is 20  minutes. Compare this with 99 minutes with the digital equivalent. Also these analogue (dial) controlled ultrasonic tanks don't have degassing.
