Features:37 kHz ultrasonic frequency (control range -2,5 / +5,5 kHz)5 ultrasonic modes for need-based sound field distribution in the ultrasonic bathEco-mode: Gentle cleaning with quieter operation by running the sweep-mode at a slightly lower intensitySweep-mode: Even cleaning through even sound field distribution in the ultrasonic bathPulse-mode: Removal of even stubborn contamination through pulsating sound field distributionDynamic-mode: Combination of the ultrasonic modes sweep and pulse in order to increase the cleaning performanceDegas-mode: Quick degassing of the cleaning liquid and for special applications in the laboratory4 memory locations for cleaning programsAutostart function for temperature-controlled start of cleaningAdjustable limit temperature from 40-60 °C (can be switched to °F)Digital control unit with wipeable membrane keyboard and easy-to-read display for displaying all operating statesOptical and acoustic feedback, e.g. at the end of cleaning or when the limit temperature is reachedPre-selection of cleaning time: cleaning time adjustable between 1 minute and 6 hoursElectronic temperature control adjustable in steps of 5 °C from 25-80 °C (can be switched to °F; temperature tolerance -5 / +8 °C)Setup menu for individual adjustment of the device functionsDry-run detecion (except for Elmasonic Select 500 and 900)Automatic safety shutdown after 8 hoursSplash-proof case and cleaning tank made of stainless steelShut-off valve on the side for emptying the cleaning tank via the outlet on the rear of the device (only for Elmasonic Select 60 to 300)Shut-off valve and outlet on the side of the device for emptying the cleaning tank (only for Elmasonic Select 500 and 900)Soundproof lids reduce the noise of the ultrasound, the evaporation of water and chemicals, and the waste heat. Thus, energy and costs are saved.
