Sort By Operating Control Type
With a couple of exceptions, there are three versions for most sizes of ultrasonic cleaner. In summary, the more you pay for a tank, the greater control you have over the cleaning process. The manual (dial adjustment) machines give limited control. The digital range gives you full control over the cleaning operation and has degassing as standard. The top of the range has degassing and sweep function. These models give a deeper clean and have the ability to reduce the power for delicate items.
The most frequently asked question is "what's the difference between dial control and digital"?
Answer: With dial control, the timer is mechanical with a maximum time of 20 minutes before it "pings out". You can of course set it again for another 20 minutes. The digital machine is microchip control and will run up to 99 minutes. The digital machines also have degassing (please read the section below).
Manual (dial) adjustment. The analogue models have a simple knob or dial to set the cleaning time (0-20 minutes) and temperature (20 - 80 degrees C). There is no LED display.
Digital adjustment with degassing. These ultrasonic models have a push button to set the cleaning time (0 - 99 minutes) and temperature (0 - 80 degrees centigrade) with an LED display. The cleaning process can be stopped mid-cycle and the LED display shows both the target temperature and actual water in the tank.
Degassing is standard on our DK Sonic digital range. This quickly removes air from the liquid after a change of cleaning fluid, which in turn, makes the cleaning process more effective. This is especially useful when cleaning carburettors.
Digital with degassing, sweep and touch screen control. The sweep function automatically alternates the ultrasonic cleaning frequency between 40Khz and 33Khz. This is means the item to be cleaned is sprayed with ultrasonic waves at two different frequencies, dislodging dirt / matter that otherwise might not be removed. This is ideal for cleaning PCB's. Additionally, the cleaning power can be reduced by 50% for delicate items. The functions are actuated via a touch screen panel.
