Wall-Mounted Ozone Analyzer

Based on Lambert Bill's law, the analyzer of by measuring the change of the intensity of the light signal before and after the UV absorption to calculate the current ozone concentration.The equipment adopts the advanced dual UV light source system with the intelligent management system of the lamp tube and separated photocell technology that enables the analyzer has the characteristics of no leakage, anti high pressure, anti sampling gas impact.

The Wall-Mounted Ozone Analyzer has touch screen operation interface, which shows the real-time ozone concentration. And the touch screen is also with pressure & temperature compensation display. For the high concentration (g/Nm3) range, it has the function of flow input, which can display the output of the ozone generator in real time. The core component adopts long-life uv light system with the high light transmittance quartz to prevent zero drifting from affecting the detection accuracy. It’s no need to close ozone inputing when zeroing to ensure the equipment can run continuously 24 hours.

The ozone concentration is displayed in either percent weight of ozone (%wt/wt), grams of ozone per normal cubic meter of sample gas (g/Nm3) on alphanumeric display. The concentration unit can be changed during operation.

Operation instruction

【1】.Using condition

This analyzer is used for indoor installation and operation. It is recommended to preheat for 5 minutes and then zeroing one time. It can be used online for 24 hours. Please pay attention to safety of power and environment when using. It’s equipped with UV LED light source monitoring system, and the system will be adjusted according to the brightness of the light source. If zero deviation without ozone, you can manually zeroing to clean. Occasionally, zero deviation occurs, which can be ignored.

【2】 The cautions

①This ozone analyzer is used for indoor and the environment should be kept ventilated, dry, no other corrosive gases. In particular, if there is ammonia, hydrogen chloride, hydrogen sulfide and other gases in the environment should be timely protected from corrosion. Any problem caused by this condition is not within the free guarantee.

②Clean and dry ozone gas must be guaranteed. If need detect the concentration of ozone gas in humid places or with oil, dust, filters (flue gas filters) and dehumidifiers (electronic condensers) must be installed at the inlet of the instrument. Otherwise any problem caused by this condition is not within the free guarantee.

③It is strictly prohibited to connect the exhaust gas destroyer outlet to the main pipeline, and the exhaust gas must be emptied or destroyed.

④If the instrument is not used for a long time, it is necessary to electrify the heater regularly and store the instrument against moisture

⑤Exhaust gas destroyer in the working state will be enthusiastic, It’s strictly prohibit hand direct touching. Pay attention to the exhaust gas destroyer will be invalid if long-time in moisture insulation. If found the ozone gas overflow at the outlet, please contact the manufacture to replace it.

⑥The inlet connection pipe should use the PTFE material.

⑦The manufacturer's air filter can only filter dust particles. If user needs to detect the ozone gas with oil mist, water mist and other media, please contact the manufacturer in time to customize pre-treatment device.

main interface-normal display function    

"Working", "calibration" and "error" are displayed in the lower right corner of the main screen display interface.

●WORKING: run test status

●ZEROING: the instrument is in zero calibration operation

●ERROR: ozone analyzer failure. Please contact the manufacturer in time.

●LOADING:After the instrument is turned on, the hot machine displays the loading status

Zeroing menu

Users can choose between "manual zero calibration" and "automatic zero calibration" modes according to the situation.

The automatic zero calibration interval time can be set by users according to their needs.

When the ozone concentration value is detected to be≥100g/Nm3, the manufacturer recommends an automatic zero calibration time of 24-96 hours.

When detecting ozone concentration values≤100g/Nm3, the manufacturer recommends an automatic zero calibration time of 8-12 hours.

The "Manual Zero Calibration Once" button, when triggered, performs a zero calibration operation on the ozone gas concentration analyzer.

Signal menu

Users can set up "high alarm points" and "low alarm points" according to their situation. The instrument with two sets of relay signal output, users can connect two sets of NO, COM, NC relay signals.

When using relay signals, it should be noted that relay signals should be DC power input with a maximum of 24V.Try to avoid direct access to relay signals by 220VAC.

Setting menu

a. Users can set "temperature compensation" to bring values to "open" and "close" locations which with ozone concentration calculations.

b. Users can set "pressure compensation" to bring values to "open" and "close" locations which with ozone concentration calculations. This instrument pressure transmitter support pumping sampling and active pressure compensation.

c. Users can choose the unit as below according to the situation:

Additional explanation:

The units of g/Nm3 & g/m3 NTP mean the ozone concentration at the standard temperature ( 20℃ probably）and the standard pressure (101.325 KPa).g/m3 NTP

（NTP- normal temperature and pressure，STP- standard temperature and pressure）

g/Nm3 is an expression of international expression. The display follows the international practice and adopts the expression mode of g/Nm3 concentration.

DATA menu

View the main screen of the parameter menu.

The data values in the parameter menu are the same as the parameter indicators used by the manufacturer's technical personnel to evaluate the performance of the ozone analyzer. This parameter page displays the various parameters of the dual path ultraviolet absorption ozone analyzer, used to determine whether the ozone analyzer is in normal detection and display status.

●UVLED-R: the reaction is the UV light source in the absence of gas light intensity parameters.

●UVLED-M: the light intensity parameter of UV light source after passing through the detection chamber (light cell).

●DATA-ZERO andDATA-ABSR are a parameter data value obtained by ozone analyzer according to bill Lambert Law and program algorithm.

System status: "NORMAL" and "ERROR" can judge whether the ozone analyzer can work normally according to the calculation of instrument parameters.

●TheLED-Svalue is the user's ability to recalibrate the ozone gas concentration sensor data based on changes in the current concentration.

The reference ratio reflects the intensity of the current ultraviolet LED light source when it has not been exposed to gas.

The reference value reflects the parameter of the illumination intensity of the ultraviolet LED light source without passing through gas during zero calibration.

Automatic adjustment function: The instrument background will record the brightness (reference value) of the ultraviolet LED during zero calibration. When the brightness of the ultraviolet LED deviates, the system will automatically correct the brightness of the ultraviolet LED, so that the zero point of the ozone gas concentration sensor is automatically adjusted within a certain range, effectively avoiding zero point deviation.

Debug menu

Debugging mode menu is the basic settings and for adjusting parameters. Users do not try to enter the password menu, when the password error reached a certain times, the instrument will automatically locked with blue screen.

This operation background interface and settings can modify and modify the parameters of ozone analyzer, such as "concentration coefficient", "UV lamp brightness", "4-20mA value", "temperature", "pressure", "photoelectric receiver parameters", "correction value", "return to zero value".
