NDJ-79 rotational viscometer is a precision instrument which is suitable for measuring absolute viscosity and apparent viscosity of various Newtonian liquids in laboratory and factory. The viscometer can be used to measure the viscosity of petroleum, resin, paint, ink, slurry, cosmetics, cream, medicine, asphalt, etc. For different viscosity liquid or different measurement requirements, different measurement units can be selected for measurement. The viscometer has the advantages of small volume, light weight, convenient use, simple maintenance, durability and rapid and reliable determination of liquid viscosity.
1. The instrument is driven by micro synchronous motor, which can rotate at constant speed and is not affected by load and power supply voltage.
2. There are two kinds of test units, each of which includes a measuring container and several rotating cylinders with rotating shafts, to meet the test requirements of each sample.
3. Novel design, arc dial, easy to read.
