Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

1.Introduction: Digital LCD Viscometer, applies stepping motor based on 16-bytes microcomputer processor, with blue screen TFL-LCD. with even rotate speed, distinctive keystrokes, programming, and alarming system, and also it’s easy to use. Displayer tells directly viscosity, rotary speed, temperature, centesimal torsion, serial number of the spindle and maxim viscosity that can be measured at present rotary speed of the spindle used. Master control board and Subdivides the actuation board completely to use pastes the piece technique. The circuit is designed by the most advanced microcomputer processor in the world, thus the structure is reasonable and compact. The full scale and levels of lineal measure are measured and adjusted through a PC interface, whose measuring capability is up to the advanced standards of similar types abroad. 2.Specification: Display: English Power supply: AC110V-AC220VMeasuring Range cp(mPa·s): 1-2000k(mPa·s)Speed Range(RPM): 0.3RPM 0.6RPM 1.5RPM 3RPM 6RPM 12 RPM 30 RPM 60 RPM(Have no wheel gear arouse)Number of Spindles :4 kinds(The 0th rotor for select and match)Accuracy:...
