255-211 Replacement Graduates

Replacement Graduates are used to measure the volume of water that was evaporated from an evaporation pan. They are often used in conjunction with a 255-210 Stillwell with Fixed Point as a reference. The graduate has a surface area of 1/100 that of the NovaLynx 255-200 Class A Evaporation Pan.

• • Model 255-211E is scaled in inches, therefore each line represents 0.01" of evaporation.
