0 to 4 GPH Pump Calibration Column, Glass with CPVC End Caps (each)

Koflo pump calibration columns (also known as calibration cylinders) provide a simple method for determining pump flowrate using industry-standard graduations of milliliters/minute and gallons/hour. All columns feature top-aligned graduated scales that allow the operator to survey both ml/min and GPH in a single, one-minute test. High-contrast blue lettering enhances readability in all light conditions, and all scales have a protective lamination layer to protect against chemical attack.

Glass pump calibration columns feature a borosilicate glass interior for extreme chemical resistance and an even higher level of readability when compared to PVC columns. The new design offers an integrated polycarbonate shield for full double-containment of corrosive chemicals with the added benefit of industry-leading impact resistance.
