An overview,

The ozone analyzer is a domestic high-end technical product. On-line continuous detection of ozone gas can be realized. The instrument adopts imported devices, with high precision, high sensitivity, fast response time and other characteristics. The data are operated by special design and development management software and displayed on the touch screen in real time, which is convenient for operation and real-time detection of concentration. Humanized design, easy to operate, install, carry. The product can be traced to the Ozone reference unit SRP41 of the National Institute of Metrology (SRP41 can be traced to the International Bureau of Metrology BIPM).

Two, the working principle

Oxygen molecules generate ozone molecules through arc discharge, and ozone molecules absorb ultraviolet light with wavelength of 253.7nm. Through a specific light pool, ozone molecules absorb ultraviolet light with wavelength of 253.7nm, and the intensity of absorption ultraviolet light is proportional to the concentration of ozone molecules. Lambert-beer law can accurately measure the ozone concentration.

Four, work environment requirements

The installation environment is mainly a special laboratory with no vibration, no impact, no electromagnetic interference, no high frequency, strong electric field interference, good ventilation, less dust, no interference gas around, direct sunlight, and good ventilation facilities.

V. Equipment composition and connection

Ozone analyzer mainly includes display part, control part, detection part, etc., the back side of the device interface is mainly: ozone inlet, zero air inlet, emptying port.

1. Preparation before installation

Pipeline material: The pipes connecting the gas path are ptfe pipes.

Zero air source: compressed air or zero air generator can be provided, or ambient air can be used as zero air.

2. Connect the air path

The "ozone inlet" of the device is connected with the detection gas source. The input of the air source is self-priming type, and the discharge port needs to be connected at the front of the inlet to prevent excessive pressure from damaging the instrument.

The "vent" is directly discharged from the ventilation facility.

Six, operation instructions

1. Instrument preheating

A. Turn on the I/0 switch of the device and preheat for about 30 minutes;

B. Open the exhaust switch at the same time for exhaust;

C. After power on, the computer power switch on the front panel automatically opens, automatically opens the software operating system, and enters the operation interface.

2. After the instrument operation is preheated, turn on the other instruments in turn.

A, first open the fume hood;

B. Switch on the detected gas source,

C. After the system display is stable, the corresponding recording work can be carried out;

E. After the operation, first close the air intake source, then close the device and computer, and finally close the ventilation facilities.

3. Software operation

After the power is turned on, the computer will start automatically and open the software to enter the working interface, as shown in the picture

Click "File" → "List Display", or click the picture on the upper part of the software to display the detailed dynamic data at the bottom of the interface. If you need to save the data, click "Save", and the saved file can be named freely.

When you do not want to display dynamic data, click "List display" or the upper part of the software with pictures.

Click the black unit symbol "PPB" on the right of the digital display box to switch between different display units.

"Parameter Setting" and "Calibration Setting" are forbidden to be operated at ordinary times and only used when the instrument is calibrated.

4. Precautions

A, before operating the instrument, be sure to open the fume hood first.

B. Pay attention to personal safety during operation.

C. The input of air source is self-priming, and the discharge port needs to be connected at the front of the entrance to prevent excessive pressure from damaging the instrument.

D. Timely close the equipment when not in use;

E. Do not place in high voltage, high magnetic field, high frequency and other electromagnetic environment to avoid mutual influence.

Seven, instrument maintenance and maintenance

1. Use the instrument and its supporting facilities correctly, and operate in strict accordance with the requirements.

2, environmental requirements: shall not be placed in the damp, vibration, voltage instability, strong magnetic and strong electric interference, dust places to use, should be installed in a well-configured laboratory; Avoid power outages to prevent data loss.

3. Avoid direct sunlight to avoid affecting the optical sensing system of the instrument.

4. Clean and maintain in time after use to avoid residue; It should also be shut down in time to avoid the loss of consumable parts caused by long-term boot.

5, regular power: long-term use should be powered on once a week, so that moistureproof and can make the instrument always remain in the working state, not in the long-term shutdown of the instrument performance indicators have obvious changes.

6. Periodic calibration: In order to ensure the accuracy and reliability of the instrument testing data, periodic calibration is recommended.

Viii. Transportation and storage

1. When the instrument needs to be transported, protective measures should be taken. It can be transported according to the original packaging, and falling and tumbling must be avoided. Must prevent rain, exposure to the sun and violent impact.

2. The instrument should be stored in the packing condition before use. The indoor temperature of the instrument should be 0-40℃, the relative humidity should not be more than 85%, and there should be no corrosive gas in the room.

3. When the instrument is not used for a long time, it should be stored in a cool and dry place, and cleaned regularly to avoid dust and direct sunlight.
