What does everyone think of this refractometer, does anyone have it?

Not cheap, take a 30$ on and calibrate it with 1.0265 solution

Where do u get that from? Couldn't i just use RO water and set it to zero

 

[Icefire]

using RODI to calibrate it is for near 1.000 reading.

ebay have some, RC sponsor too

Why would i use the 1.0265 solution over RO water? Other than one being free and the other you have to order and when you calibrate it setting it to different numbers. Is there a better accuracy when using the solution?

 

[Icefire]

better accuracy. would you use a 0-3000F thermometer to mesure ambiant temp? better use some calibrated to the closest of what you want to read.

Get some Pinpoint 53ms fluid.

Same with PH probe, we mesure ~8 so we calibrate with 7-10.01 and not 4-7.
