Huion PW550 series pens notes

Buttons

These pens have two buttons which is typical for an EMR pen.

Pressure testing notes

I tested four PW550 series pens on 2024/08/30

• 1x PW500S

• 4x PW550

Pressure: IAF

I'm not good at measuring IAF but each seemed to be around 3gf.

Pressure: max pressure (approximate)

3 of 4 of the my PW550 pens have GOOD or EXCELLENT max pressure. One outlier has an OK max pressure.

Pressure: Response curve

As is typical for EMR pens, these pens have a response that bows up. All 4 hit 50% at around 100gf.

So as I often recommend, you should consider a pressure curve to linearize this response so that you have more pressure control at the lower end of the physical pressure range.

PW550 versus PW517

The PW550 may be a compelling upgrade to the PW517 pen. See the details in the video below.
