Low-cost and easily-operated microviscometer suitable for medical diagnosis clinical studies and other fluid tests. The equipment consists of a microchannel (2) formed by concatenated microchannels made by micro-manufacturing techniques, and a fluid column position detector inside the microchannel. The microchannels are open at one end and closed at the other end and are made of a single biocompatible material. When a liquid drop is put into the inlet of the microchannel (2), the fluid enters by capillary until the compressed air pressure equals the capillary pressure plus atmospheric pressure. The fluid transient movement from entering the channel until stopping at its balance position is analyzed thus obtaining as a result the viscosity and the capillary pressure of the liquid tested.
