Instruction Manual

Notes before Operation

1. Notice before operation:

（1） Carefully read the relevant parts of this manual before installation and operation to prevent wrong

operation, measurement error and damage of instrument.

（2） Improper installation and unsuitable flow speed will cause big measurement error, so please read the

installation passage in detail.

（3） This instrument is precise electrochemical measurement, and its installation and operation should be

performed by technicians with relevant professional knowledge.

（4） If for some special conditions, please consult our Technical Department for further details.

2. Maintenance items:

（1） The indicators’ quality guarantee is one year from the date of purchasing. During this period, if the

meter has quality problems, manufacturer is responsible for maintenance work for free or changes it.

（2） pH and ORP probes are consumer goods which without quality guarantee. Because, the lifespan is based

on the medium and working conditions.

（3） Manufacturer offers the maintenance service for whole life of the sold meters.

（4） If the damage of the meter is caused by the following reasons, it is out of the maintenance service:

A、The meter is burned or foundered caused by improper usage and maintenance.

B、The meter is refitted or misused without permit.

C、The meter is destroyed under the condition out of company’s regulation.

D、The relevant damage caused by choosing the wrong type.

E、The cable damage and rupture caused by improper installation and usage.

F、The incorrect measurement of the probe caused by disconnecting or connecting wires personally.

G、The measurement inaccurate caused by privately cutting the probe cable.

H、

The inner broken wire caused by indiscreetly disassembling.

I、The consumptive materials are not within the scope the warranty.

ⅠCONCEPTION

pH/ORP-5500 series pH/ORP Transmitting Controller is a popular type,high Cost performance

instrument, mating pH/ORP probe,the entire instrument have high measurement accuracy,

anti-interference,easy installation,simple operate features.

1.1 Main Features

1. LCD screen with prompt code, make every step operating get the presentation and guide;

2. Programming pH＆ORP function can be switched,suit any type of pH＆ORP probe;

3. Support six types of buffer calibration which can free combination，greatly broaden the

application scope;

4. Innovative manual input calibration method provide the biggest convinence for site

calibration

5. Selectable manual/automatic temperature compensation measurement type,providing the

largest flexibility.

6. Independent external automatic temperature compensation probe provide high measurement

accuracy.

7. Isolated/transferable /Reverse /instrument/Transmitter mode current output，compatible all

the transmitting receive modes.

8. Double relay’s high/low limit and delay control satisfied pH or ORP region control and

dosing；

9. Mating split style、double combination probe easy change，one time wiring，permanent using

（see the pH/ORP1220Aseries instruction）；

10. Industrial standard terminals，EMC electromagnetic compatibility measurement，platform

design and development, series grouping；

11. Satisfy world electric power supply standard，DC/AC power input nonpolarity connection，

site operation will not worry about wrong connect;

12. SMT Automatically Surface Mount Technology,AOI Automated Optical Inspection,ICT,

FCT Full Computer Test,quality control means make, reliable quality；

13. Every instrument make aging test，surface processing treatment，Full equipped electrical

productive technology，high quality level；

14. Calibrate the probe one before leave factory；

1.2 Application

This instrument is used for pH/ORP online monitor in environmental protection of water

treatment, purified water treatment, industry process, aquaculture and etc

1.3 Note：

1. The instrument should place in dry environment or control box to avoid the sputtering or

condensation water causing leakage or measurement error

2. This series instrument is platform develop result, various power supply can select, pls pay

attention to the voltage class when install the wiring；

3. long time ultraviolet rays shining will burn the screen，result the gray scale reduce，so avoid installing

direct sunlight place.
