From the sellerAttracted by the bubble that seemed to have some inclinometer application, here it is. Unknown use to me. I don't see any liquid in "thermometer tube". Appears to mount on a larger piece of equipment or bench. Anyway, interesting instrument. glass not broken. Marked in inches, by 10ths. Rash on metal. 14" overall.
