Bathythermograph grids

A bathythermograph grid is a transparent glass slide, marked with calibration lines of temperature and depth, that, when superimposed against a bathythermograph slide, makes it possible to read observed values of temperature and depth.

This is a group of nine bathythermograph grids, each in a grey plastic holder containing glass slides marked with a grid; one grid in an envelope without box.
