Hemispherical Copper Water Bath Chemical_Iodine Rotation-wheel water flow data-logging sensor

Rotation-wheel water flow data-logging sensor reading 0 to 4

Use for investigation of gas at constant volume By inserting the glass bulb into either warm or cold water the expansion and contraction to the air contained in the bulb can be seen as a pressure change on the gauge

Used as a primary standard in permanganate titrations and as a chelating agent for iron-stain removal
