Figure 4 Electrodes
1.6 Industrial Process pH Electrode
The Hach Industrial pH Electrode’s unique design does not use an electrolyte pump and
does not have a replaceable sensor. The low-maintenance electrode has self-pressurized
electrolyte and a flat electrode. The electrode features high temperature and pressure
resistance and is designed for traditional applications such as water and wastewater
analysis. The electrode is housed in a CPVC body with a built-in preamplifier and has the
same size and shape to fit all of the mounting configurations described in SECTION 5,
INSTALLATION.
1.7 Sample Handling System
Three sampling techniques can be used with the EC1000 pH/ORP System: submersible,
flow-thru cell, and in-line installations. Mounting kits are available for the different
applications. Refer to SECTION 5, INSTALLATION for detailed installation information.
1.7.1 Submersible
For the submersible application, mount the electrode to the end of a pipe using the
Submersible Mounting Kit (Cat. No. 46401-00), see Figure 15 on page 61, and place it in
a tank or non-flowing sample.
1.7.2 Flow-Thru Cell
The Flow-Thru Cell provides for atmospheric sampling of the process water, and easy
installation and removal of the electrode. Mounting Kit (Cat. No. 46403-00) is required,
see Figure 16 on page 61.
1.7.3 In-Line
For the in-line application, place the electrode directly in-line with the sample through a
“Tee” pipe fitting using the In-line Mounting Kit (Cat. No. 46402-00), see Figure 15 on
page 61. Pressure reducers may be required if the sample pressure is greater than 35 psig.
