EP402 Series small-bore ow-through assemblies are designed to be utilized with an electrodeless large bore PEEK
sensor to provide a full-range conductivity measurement of any process solutions encountered. Examples of commonly encountered applications include NaOH, NACl, HCl, H3PO4, KCl, KOH, and others where standard sensor mountings are impractical, or where quite low, often single-digit conductivity is desired (e.g., condensate).

The ability to select from a long list of wetted materials (e.g., end connection, bore piece, and O-ring) permits the EP402 Series units to be tailored to the speci c conductivity application at hand.

For example, select from Hastelloy C, titanium, C-20, 316 ss, and other metals for either threaded or triclamp end connections. Select from glass- lled PEEK, glass- lled Te on, or PVDF, PCTFE, and other thermoplastics for the appropriate bore piece. And from EPDM, Viton, Kalrez, or Chemraz O-rings for whatever your applications require.

A choice of small bore sizes, for example, 1/4”, 3/8”, 1/2”, and 5/8” permits the measurement of very low- ow conductive uids. The available small bore sizes also help prevent ashing in higher- temperature low-conductivity applications, such as condensate.

Use any EP402 with the appropriate range 871EC large-bore PEEK sensor, e.g., 871EC-LBO for low-conductivity.
