Hey guys I got in a nice set of remeshed screens and it seems like some of them are mislabeled.
Of course I've lost the 3 in 1 mesh determiner.
Before I drop the cash on another one I figured I'd ask, does anyone have a file I can print out on my own for this purpose?

I would send you mine but I don't think it would work for a few reason's coming from my setup to your setup....I might try later to scan and print mine to see if it would work.

On the other hand, if you have some known examples as a gauge, with a little practice, one can recognize the sound made with a gentle stroke of a fingernail, especially if there is a big jump between mesh count numbers.
A 110 sounds obviously "rougher" than a 260, but experience and finesse will play a part in identifying the ones in-between.

if YOU HAVE A DIGITAL (CHEAP) MICROSCOPE you can work this out.
I have 2 microscopes and each came with a calibration / measurement film that is set up in microns uM and such.
next you will need a typical screen mesh tech sheet reporting the mesh open area of the weave. I have attached one here for your reference.
for example from the chart below, a 160 mesh screen reports 111 microns mesh opening, a 180 reports 93 microns opening and so on.
Throw the calibration film on your print screen fire up your microscope and see what you can see measurement wise .
not the most accurate way but in a pinch you can at least determine an approximate ESPECIALLY if you have other screens with know mesh count.
At any rate if you do not have one of those handy dandy digital microscopes get you one it opens up a whole new world.
here is a typical Amazon example well under $20.00 ;) https://www.amazon.com/gp/product/B01M2XK6BV/ref=s9_acsd_newrz_hd_bw_b25r8_c_x_w/161-0269571-6954641?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-5&pf_rd_r=GD9M6GB9GRBKJZ21E10S&pf_rd_t=101&pf_rd_p=af133a9d-d398-576c-8d7a-f6f89d65492a&pf_rd_i=499170 (https://www.amazon.com/gp/product/B01M2XK6BV/ref=s9_acsd_newrz_hd_bw_b25r8_c_x_w/161-0269571-6954641?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-5&pf_rd_r=GD9M6GB9GRBKJZ21E10S&pf_rd_t=101&pf_rd_p=af133a9d-d398-576c-8d7a-f6f89d65492a&pf_rd_i=499170)

Thanks for the replies, very helpful!

A mesh determiner should tell you more than just count but rather the warp and weft reading will tell you just how square/balanced the mesh is after stretching.. After balance is achieved (with the mesh determiner) you then use the tension meter to read at a given tension warrp and weft my S/S curve for that specific thread count on this brand of mesh is- (write the required tension warp and weft down for the next time you stretch that particular mesh)
You can even use marks on the mesh and strech the screen so that the mark moves a specific distance towards the frame-warp and weft- (this is stretching by percentage of elongation), use the mesh determiner for balance then record what the tension meter says..
My question is what else does knowing the exact thread count inform us about?
