With a unique sweep frequency tech to eliminate standing waves, & a pioneering 40 kHz industrial transducers, Bransonic ultrasonic baths have been the industry std for quality, reliability, & precision cleaning.Constant activity/power tracking automatically maintains the ultrasonic power by adjusting for changes in liquid level & temperature caused by a light or heavy load. This helps ensure more uniform cleaning & consistent performance.High/low power control adjusts the acoustic energy in the bath & can be set at 100% power for normal to heavier loads or at 70% power for lighter, This helps to protect components from potential damage.Temperature settings up to 69°C/156.2°F can be set in Celsius or Fahrenheit & programmed through the front panel for easy access & monitoring. High-temperature visual alarm/auto shut-off provides added safety.
