Precision coffee tamper designed to deliver consistent, repeatable tamping for better extraction and fewer channeling issues. Key benefits Accurate pressure control: A clear side dial lets you rotate to set pressure like a volume control. Adjust from light to deep roast beans without guessing by feel. Consistent tamping force: Hengli Spring Design provides a calibrated, professional spring that applies uniform force every press, so beginners achieve steady results comparable to experienced operators. Automatic leveling: A selfbalancing base with a horizontal correction ring automatically levels the tamp with a gentle press, reducing uneven extraction and the channel effect. Reliable, repeatable compaction: Factorycalibrated powder compactor ensures the same pressure each time. The bottom antislip pattern increases friction for easier, more stable pressing. Features and performance Pressure adjustment: Clear, tactile dial for incremental pressure changes to suit different roast levels and extraction targets. Builtin spring mechanism: Professionalgrade spring delivers uniform downward force on every tamp. Selfleveling base: Horizontal correction ring aligns the base to the portafilter bed to minimize tilt and uneven puck density. Calibrated compactor head: Factory set to provide consistent pressure; textured base reduces slippage during tamping. Practical for varied beans: Effective across the spectrum from light to dark roasts where tamp pressure affects extraction. Use scenarios Home espresso: Quickly set an appropriate pressure for lighter roasts used for singleorigin espresso and maintain consistent tamping across daily shots. Barista training and small cafes: Helps beginners learn repeatable technique and ensures uniform puck preparation during busy service periods. Coffee quality control and roasting tests: Apply identical tamping pressure when comparing extraction across roast profiles or recipes. What this solves Removes guesswork in tamp pressure and consistency. Reduces uneven extraction and channeling caused by misalignment or inconsistent force. Makes tamping easier and more repeatable for users of varying strength and experience.
