I want a scale with something like this for static firing, anyideas? I am here because the company is selling is for nealry 800$ and wow, im not very rich!

so I want a digital scale and preferably a pressure gauge which can transfer data to my pc via one of these - USB2.0, USB3.0, VGA, or mini display port.

thanks.

The cheap version is too slow, at 1 sample per second. This will only allow for a very crude approximation of the thrust curve and hide pretty much any detail that a motor builder might be interested in. Also, if a piece of software requires administrative rights for regular use, seven years after Windows Vista has been released, I strongly suspect that development has either been abandoned or that the developer can't be bothered to write proper software.

The expensive version looks fine at the first glimpse.

Ahh wow thanks so much!

and yeah, as Reinhard said, its dissapointing the scale only read once per second.
