How To Choose An Ultrasonic Cleaner

Ultrasonic cleaners have become ubiquitous and get recommended for many cleaning operations. Depending on your cleaning requirements however, there are certain factors you should consider to avoid disappointment. When you make the right choice the savings in time as well as cleaning efficacy will more than pay for itself.

Before selecting, consider your needs. Figure out exactly what you want the ultrasonic cleaner to well, clean. Some ultrasonic cleaners are suitable for casual or delicate items while others are for heavy duty scrubbing.

Features to Consider

Size - Make sure that your items will fit inside the tray of the ultrasonic cleaner. Take note of the tank volume and internal dimensions. If you are just going to clean a few small items on most ultrasonic cleaning sessions, then you may not need a cleaner with a large tank. A smaller cleaner will require less cleaning solution and energy.

Cycle Time - 15 to 30 minutes cycle time is enough for cleaning most items. If you are comfortable with turning on the heater several times during a cleaning session, then a cleaner with low cycle times may be suitable for you. However, if you want an ultrasonic cleaner that needs little supervision, choose among those that have longer cycle times. For items that have tough layers of dirt and grime you will need to look for units with longer cycle times at least 30 minutes. For things like jewelry, a lower cycle of 10 minutes is fine.

Frequency - The frequency of most ultrasonic cleaners lie somewhere between 35 to 45 KHz. Make sure to pick an ultrasonic cleaner that produces frequencies at this range. Higher frequencies may damage your items, while lower ones may reduce a cleaner's effectiveness. If the frequency is missing on the product description, ask your vendor.

Power Rating - While frequency determines the rate of vibration, power rating determines the strength of the ultrasonic waves generated by the cleaner. More power means more cavitation and thus greater cleaning power. Be sure to check the ultrasonic power rating independent of the overall power rating. Also, watch out for "peak power" specifications. Some lower priced manufacturers will play around with these terms and values to make a low powered unit seem like a high powered one. Like the infamous PMPO (Peak Music Power Output) in audio speakers.

Heater - Heat enhances the effectiveness of the cleaning solution. Some cleaners have a built-in heater installed on their system, although they more expensive. These heaters may even have controls that maintain the temperature of the medium. If you are going to use hot water as a cleaning solution, then buying a cleaner without a heater would be fine.

Degassing - This is an optional but useful feature. Cleaning solutions usually contain air bubbles and non-dissolvable gases that impede effective ultrasonic cleaning. The degassing feature will prep the solution and remove the trapped gases.

Warranty - Most ultrasonic cleaner manufacturers offer up to 2 years parts and labor services guarantee. However, you will need to send the device to their support centers for repair or replacement. Ask your vendor about the warranty details. Sometimes, your vendor will be the one to contact the manufacturer. However, if that is not the case, make sure that the warranty services are easily accessible through the manufacturer's website or repair centers.

Tips Before Buying

When you've narrowed down your models, run a google search for the unit with the word review in the search term (e.g. review Elmasonic e line). If you are a hobbyist or have specialist cleaning needs check with your peers and fellow hobbyists in the forums. You may also ask me through our website http://www.tovatech.com/ultrasonic-cleaner/.
