This instrument is a special test instrument designed and manufactured according to the national standard gb265-88 petroleum product kinematic viscosity measurement method. It is suitable for measuring the kinematic viscosity of liquid petroleum products.

This instrument has the time of timing sample movement, and calculates the final result of motion viscosity automatically.

This method is applicable to the determination of the kinematic viscosity of liquid petroleum products (i.e., Newtonian liquids). The unit is m2/s, which is usually used as mm2/s in practice.

The kinetic viscosity can be obtained by the measured kinetic viscosity times the density of the liquid.

Under this method is in a constant temperature, the determination of a certain volume of liquid under gravity flow through a calibration good glass capillary viscometer, the product of the capillary viscometer constant with the flow of time, as the temperature determination of kinematic viscosity of liquid.

The kinetic viscosity at the temperature and the density of the liquid at the same temperature are the dynamic viscosity of the temperature.

A 6 phase relay protection tester differs from its 3-phase counterpart in one fundamental way: it provides six fully independent current channels and up to six voltage outputs simultaneously. That independence matters enormously when you're testing busbar differential protection, three-winding transformer protection, or running an end-to-end relay test across two remote terminals. With a standard 3-phase set, you're often forced to run tests in stages or reconfigure mid-job — both of which introduce errors and cost time.

The HZDL-1000III three-phase high current generator (referred to as three-phase current regulator) is a testing equipment independently developed by our company.It combines the advantages of similar products at home and abroad, adopts CNC technology, and has strong anti-interference ability.
