HumminGuru S-DUO is a compact device that combines ultrasonic cleaning and digital pressure gauge in one place for the care of the turntable stylus. With smartly-designed 2-in-1 feature, it does both steps of stylus cleaning and downforce measuring in one go. The whole process is effortless and only takes the user less than a minute to complete. Its easy & quick operation, convenient use, storage, and portability make the cleaning experience seamless and pleasurable.

Ultrasonic Cleaning

The HumminGuru S-DUO uses 110kHz of ultrasonic cleaning frequency which creates much smaller cavitation bubbles to remove dust, grime, and hardened dirt off the stylus tip thoroughly. The ultrasonic frequency of the cleaner is carefully selected and matched with an optimal amount of electrical power to avoid any damage and achieve effective cleaning in a safe manner. The process takes only 20 seconds by default with 3-4 drops of water (±0.3ml).

Digital Pressure Gauge

On the other hand, setting the correct tracking force of the stylus is also an essential step for ensuring the playback result and the life of the valuable records and cartridge. The digital pressure gauge is cleverly incorporated into the HumminGuru S-DUO device that makes the setup more convenient, faster, and easier for the user. With the feature of a bi-directional LCD display, the user can simply flip the device around and measure the downforce right after ultrasonic cleaning. Moreover, there is an automatic zero clearing when powering up the device, and the display value can be zeroed at any time with a simple touch of the gauge icon button.
