Actually @Zambezi Special no, I do not. Plus or minus a gram for salts and a couple of grams for hops is plenty good.

Just trying to make a point about the difference between accuracy and precision. I can't help it

 

There's a few of us here suffering the same problem. Weird in a homebrewing forum.

 

I have the same one and it's a good little scale.

 

Reference weights will do the job. I find 0.1g accuracy to be quite good enough even for small batches.

 

I bought the Triton T3 660 x .1G scale & Calibration Weight set. The scale is great & compact however the Calibration Weight set max weight is 100 g. The scale requires 500 g to calibrate. The Amazon ad says Calibration Weight Not included but it doesn't say need 500 g to calibrate. After some frustration, I ordered the 500g Weight, it was $9.97 while the 1g to 100g set was $6.51. Decided to go with no return. The 1 to 100 g set plus the 500 g was $17.50 while a complete set from 1 to 500g was $19. Already spent to much time thinking about this.
