General Information
2.3 General Product Overview
DANGER
The 8362 sc High Purity Water pH or ORP sensor is not approved for haza rdous
locations.
The 8362 sc High Purity Water pH/ORP panel is preplumbed and includes the 8362 sc
High Purity Water Sensor (Figure 1), digital electronics junction box, flow meter, and
mounting assembly. The 8362 sc High Purity Water pH/ORP Sensor contains two
electrodes; one for pH or ORP and the other for temperature.
The water runs through the 8362 sc High Purity Water Sensor then through a flow meter,
finally exiting the panel. The flow meter adjusts the sample stream from 0–300 mL/min
(0–300 cc/min.). The sensor then sends a mV signal and a temperature signal through
separate cords to a junction box which translates the analog pH/ORP and temperature
signal from the sensor into a digital signal to be read by the digital controller. Refer to
Specifications on page 5.
The 8362 sc High Purity Wat er panel is a man ufactured panel to simplify and enhance the
connection between sensor and controller. It uses a self-pressurizing reference electrode
that introduces a constant flow of electro lyte into th e sam ple st r eam. This con sta nt f low of
electrolyte reduces the effects of electrolyte oscillations that cause reference junction
potential phase shifts that are found in other measuring systems. In addition, the
electrodes are housed in a special stainless steel housing and unique conductive flow
chamber to greatly reduce the effects of streaming currents that cause pH or ORP
measurements in high purity water to drift.
2.3.1 Measurement Principle
This 8362 sc High Purity Water pH/ORP system is specially de sig n ed for continuous
measurement of pure and ultra-pure water. It uses a reference electrode similar to the
measuring electrode to minimize the impedance of the measurement. The body is made
of 316 L stainless steel, which protect s the measurements from electrostatic a nd magnetic
disturbances. The circulation chamber was designed without a retention zone to avoid
interference from CO
2
dissolution, air bubble accumulation, or insoluble deposits
accumulation (iron o xide, residues salted out by resins, etc.).

Section 3 Installation
DANGER
Only qualified personnel should perform the installation tasks described in this
section of the manual.
The panel comes pre-assembled with all the components attached. See Section 5 on
page 15 for replacement parts and accessories.
After unpacking, it is recommended to save the shipping carton and packing materials in
case the instrument must be stored or reshipped. Inspect the equipment and packing
materials for signs of shipping damage. If there is any evidence of damage, notify the
transit carrier immediately.
3.1 Mounting the Panel
1. The panel is mounted to a wall or other hard and stable surface. Choose a conv en ient
location to read the flow meter and to run cables from the controller to the panel and
the junction box. Extension cables are available through Hach, refer to Replacement
Parts and Accessories on page 53.
2. Mount the panel by using the four holes at the corners of the panel. Be sure that the
panel is securely fa stened to a void injury to persons and equipment. Refer to Figure 2
for mounting dimensions.
3. Earth ground the panel to pr otect it from electrical noise by grounding to the panel or
bring ground to the ground screw on the flow chamber.
Note: The digital controller and panel need to be earth ground to the same source.

Installation
Figure 2 Panel Mounting Dimension
3.2 Preparing for System Measurement
1. Remove the measurement chamber (see Figure 1 on page 9).
2. Remove the protective cap covering the electrode bulb and rinse with demineralized
water or pH buffer for pH measurement or ORP standard solution for ORP
measurement. Save the protective cap if the electrode will be stored for long
periods of time.
3. Replace the measurement chamber.
13
Installation
3.3 Sample Connections
1. Connect the sample stream flow to the sample-in port.
2. Connect a drain tube to the sample-out port.
Note: It is not recommended to run the sample stream back into the main flow stream.
3. Introduce the sample and visually check the measurement chamber for bubbles that
could disturb the measurement.
4. Adjust the flow to between 100–300 mL/min (100–300 cc/min) for best results.
3.4 Flow Rate and Pressure
Observe the following for optimum operation:
• Keep the flow constant at a rate between 100–300 mL/min (100–300 cc/min) at a
maximum pressure of 4 bar (58 psi) for best operation.
• Keep the drain line as short as possible to avoid back-pressure.
• Earth ground the flow chamber to protect it from external electrical noise
(Figure 3).
• Do not allow the flow chamber to become empt y. Keep the glass electrode b ulb in
water to avoid electrode damage.
• Use the protective cap filled with KCl (3 M) on the pH or ORP electrode f or storage
of up to one year. Never store your electrod e in air even if it is in the flo w chamber.
3.5 Connecting to the Controller
Connect the extension cable from the controller to the panel with the quick-connection
fitting on the side of the junction box (Figure 3). See the controller user manual f or detailed
information on configuring and using the controller.
3.6 Wiring the Probe to the Junction Box
Refer to Figure 4 and Table 1 on page 15 when installing new cables from the pH/ORP
electrode or temperature sensor to the junction box.
