3.2 Conductivity Electrode Information
The CON400 meter uses a conductivity / TDS cell with a sturdy 6-
pin connector.
Your meter includes a conductivity probe (Part No: EC-
CONSEN91W / 35608-50) Ultem / Stainless Steel cells with a cell
constant of K = 1.0. This conductivity / TDS cell features a built-in
temperature sensor for Automatic Temperature Compensation
(ATC). It has a specially designed housing that provides fast
temperature response and reduces air bubble entrapment, which
makes it easy to obtain accurate, stable readings.
Wetted parts include:
1. Polyetherimide
(Ultem™)
2. Polybutylterphalate (Valox™) 1
3. Stainless Steel (SS 304)
NOTE: We recommend that you do not submerge the probe above
the protective yellow cap for prolonged periods. The protective
yellow cap can be removed for cleaning, but must be attached at
all times during calibration or measurement.
See Section 8 on page 40 for “Probe Care and Maintenance”
information.
