control and adjustment

pH / ORP-5500 series is an online pH and ORP Controller , with plug-in PH-1110A sensor,

which has good measurement accuracy, anti-interference, easy to install and operational

features

1.1 Working Principle

A weak voltage change is generated when H+ affects the inserted sensor, the changeable value

will transmit to the instrument After converting and calculating the generated pH/ORP signal,

the instrument will show the values on the screen

1.2 Application

This series of instruments are widely used for online pH/ORP monitoring in environment

protection water treatment, pure water treatment, industrial process and so on

2.1 nstallation of nstrument

Front view

pH/ORP-5500 series is a panel mounted type instrument, which can be installed easily

Please follow the following steps:

1 Put the instrument into the Panel Cutout 91mm X 91mm (H x W)

2. Then push the quick clamp along with the trench and fasten the instrument

3. Do not let the instrument drop on the floor when dismounting the meter Withdraw the

quick clamp and take the instrument out carefully

Do not place the LCD display screen directly under the sun for the UV could damage

the screen

2.2 Electrical Connection

The measurement cable cannot be mixed with high-tension and high frequency cables To avoid

any interference, the cables should be at a distance of 30cm from high tension cables and

connected with the ground

Connect the power line and signal line according to the below Diagrams：

The actual power supply must be the same

with marked power supply !

Wiring Connection：

NPUT Connect pH/ORP measuring sensor（transparent line）

REF Connect pH/ORP reference sensor（shielded line）

CELL-T Connect the receiving terminal of the Temp sensor(red)

GND Connect grounding terminal of the temp sensor (black)
