CGOLDENWALL NDJ-5S Rotary Visometer Digital Rotational Viscosity Meter Lab Viscometers 110-240V 1-100,000mPa.s Accuracy:±3.0% (With 0# rotor)

...high sensitivity, so the test results are reliable, and also, the operation is very easy.With automatic search function, when you don't know what rotor and speed to choose, it can quickly help you find the right rotor and speed.
Application: This rotary viscometer can be used to measure the absolute viscosity of the Newtonian liquids and the apparent viscosity of the Non-Newtonian liquid. Also can be widely used in the tests the viscosity of the oil, paint, plastics, paints, detergents, drugs, jewelry and other objects.

Output power: less than 5mw, much safer for your eyes. This sturdy laser unit allows you to swiftly and precisely collimate your Newtonian telescope. Only when the optics have been accurately collimated can the telescope offer you its full performance..
Accurate collimation in a few minutes provide a more clearer image. The telescope can be collimated by just one person..
This adjustment tool can be used in all 1.25″ focusers. We provide you with precise instructions in German and English, with a step-by-step explanation of how to adjust a Newtonian telescope using this laser unit. So, even if you are a newcomer to amateur astronomy, it is very simple to get the optimum performance out of your telescope..
The precision-made aluminium housing of the laser unit has a front opening from which the laser beam can be emitted. In order to obtain an optimal adjustment, it has a side window allowing a disk oriented at 45° with a central hole to be viewed.This can be then later be used to see whether the laser is reflected back on itself, indicating well collimated optics..
The laser comes fully adjusted. It can however be further adjusted if required. It has three openings for adjustment, arranged at 120°, which are initially sealed. The battery for the ....
