The
advantages of using reflactometer
- A hand held reflactometer is
very portable.
- It is inexpensive because of
low initial cost and low levels of maintenance.
- It is easy to operate
- You just need 1 drop of fluid to do the
measurement
- The temperature does not have
to be exact 20 degrees Celsius
- There is no need to wait for
lab result it gives ınstant result.
- It can be used on most
water-based metalworking fluids.
- It can be programmed to calculate measurements with up to
5 different scales.
The
disadvantages of using reflactometer
- It can be inaccurate when
the system uses hard water with a high mineral content or when tramp oil is
present.
- Difficult to analyze
materials with lower refractive index than that of the prism.
- One must bring a possibly
hazardous material close to the eyes to read hand held refractometers.
- Less suitable for continuous SG reading in a fermenting
must or to determine the end-SG.
