What Is an liquid-free sphygmomanometer?
Aneroid Sphygmomanometers (also known as mechanical / manual blood pressure monitors) Engineered with precision mechanical structures, these classic blood pressure measuring devices remain the standard, trusted staple for hospitals, community clinics, emergency medical teams and home care settings worldwide.
No batteries or microchips required: they transmit air pressure via purely mechanical components and deliver readings through the auscultatory method. Backed by decades of clinical validation for exceptional stability and reliability, they are the top choice for areas with unstable power supply, mobile medical services and professional healthcare facilities.
Product Composition
The MC-20C liquid-free sphygmomanometer consists of PVC bulb, aluminum alloy gauge, valve, PVC tube and nylon cuff.

Product Features
1. Precision Gauge Movement
Core parts are precision-machined for tight alignment and smooth gear movement, so the pointer stays accurate and does not drift over time. The pressure sensor is stress-relieved and tightly sealed to withstand repeated use without performance loss. A thick metal case protects all internal components, and automated production ensures consistent quality across every unit.
2. Durable Cuff
High-stress areas of the cuff are reinforced with dense stitching and extra bartacks at key points, making it highly tear-resistant and less likely to fray or split. The long-lasting velcro stays firmly attached even after heavy repeated use, reducing long-term replacement costs.
3. Reliable Inflation Kit
The inflation bulb is made of flexible, resilient material. It bounces back fully after every squeeze and will not warp or harden over time. The built-in spring valve releases air slowly and steadily, making it easy to take precise readings with the stethoscope method.
