How to Select Glossmeter?

Try this.

Thank you!

But I want to purchase Chinese brands.

Then try this.

There are many varieties out there. May I humbly suggest though that you need to research a little more about measurement of light and reflection.

I could name three or four that we used for paint evaluation, but the results are compared/related to different viewing angles and different illumination sources. The combinations and permutations mean that some VERY GOOD instruments could be inappropriate for what you need.

Remember also that you generally get what you pay for. Reliability, accuracy and precision are all different parameters of such instruments and you need to understand all of them in unison.

Thank you!

Could you suggest what brands you are using now?

If the above two usernames would communicate directly on this topic using CR4's personal messaging system then any temptation to label this thread as an inappropriate advertisement would not appear.

What I last used was custom designed and built for a NATA (Australian equivalent of NIST) laboratory using components mostly from Europe.

One of our calibration artifacts cost around $10k from NML (National Measurements Lab) in the UK.

We used our own spectrophotometer to calibrate the light source intensity in 1nm wavelength increments and used that to compensate results for each source used.

One other post has mentioned a brand name that is recognised for production testing and general use.

Your initial request was for "reliability", but that may not give you accuracy or precision. You will end up with an instrument that works "forever", but the results may be neither repeatable, correct or precise.

As I suggested earlier, you need to determine your need for those features before you can specify the instrument that will satisfy your needs.

I'm an optics engineer and I work with glass and glass coatings a lot. I often see specs for glass with a certain gloss rating called-out. Almost all of the time the spec refers to a number measured by a BYK Gardner glossmeter.

According to #2⇑, though, the original poster only wants Chinese ones.

Well if I wanted to know where I stand in the market I did a market research ...

Ups, is that what it is?
