Coulometer cells are available with or without a diaphragm. The diaphragm-free cell can be used for water determinations in oils, while the version with a diaphragm is ideal for determinations of water in substances containing ketones or when the best possible accuracy is required.
Note: The picture on this page is of the actual DL32 Coulometer, which has since been discontinued. It is for representation only.
Mettler products are intended for sale/shipment within the US only. International customers should contact their local Mettler distributor to place orders for Mettler products.
