What is this device?

What is this device? The needle responds to the slightest touch and apparently measures force on the needle probe end in increments of 0-6 grams. It looks brand new and unused. There were no instructions included. Only a warning tag to treat it gently.

The red needle pushes a little black bar that stays at the point maximum pressure was recorded. It works in both left and right directions.

Looks like an older style of one of these.
A dynamometer.

It’s a dynamometer.

Thanks!

Also, I meant to ask. Can you do anything cool or fun with this?
