Page 8: Ozone Monitor Introduction
1. OZONE MONITOR INTRODUCTION The 2B Technologies Model 106-L Ozone Monitor is designed to enable accurate measurements of ozone in air over a wide dynamic range extending from a few parts-per-billion by volume (ppb) to an upper limit of 10 parts-per- million (ppm) based on the well established technique of absorption of ultraviolet light at 254 nm. - Page 9 254 nm (1.15 x 10 molecule or 308 atm ), which is known with an accuracy of approximately 1%. The 2B Technologies instrument uses the same absorption cross section (extinction coefficient) as used in other commercial instruments. Model 106-L Ozone Monitor Manual Rev. E...
- Page 10 The pressure and temperature within the absorption cell are measured so that the ozone concentration can be expressed as a mixing ratio in parts-per-billion by volume (ppbv). The instrument displays and records the cell temperature and pressure in addition to the ozone mixing ratio. The cell pressure is displayed and logged in units of mbar or torr and the cell temperature in units of either...

E... - Page 17 Data Averaging and Data Logging Using the Menu When first turned on, the instrument will start making measurements at a rate of once every 10 s. Data may be logged in the internal data logger. Up to 32,736 data lines containing log number, ozone mixing ratio, internal temperature, internal pressure, flow rate, photodiode voltage, time and date may be stored in internal memory, corresponding to an operational time of 3.8 days.
- Page 18 Overwrite Data? Warning: If you start logging, all data previously stored in the logger will be irretrievably lost. If you have data in the logger that you want to keep, be sure to download it (see below) before starting logging. Click on Yes if you are sure you want to start logging new data.
- Page 19 displayed so that the user will know how many more 10-s measurements need to be made before a new average is displayed and logged. If there is a power failure while the instrument is in the logging mode, logging will resume after power is restored. A note of “Data Interruption” will be written to the logger prior to writing the first new data line.
- Page 20 To Transmit Logged Data to a Computer Using the USB or Serial Port Connect the USB or serial port of the instrument to your computer using the appropriate cable. Enable a data acquisition program on the computer such as the 2B Technologies Display and Graphing Software, which can be downloaded at: http://twobtech.com/software.htm ...
- Page 21 Once the zero of the instrument is corrected, the slope may be adjusted so that the instrument readout agrees with a standard ozone source (such as the 2B Technologies Model 306 Ozone Calibration Source) or with the readout from another instrument whose calibration is considered to be accurate.
- Page 22 When the Cal Menu first appears, the Z will be underlined with a cursor. You may rotate the Select switch to choose the calibration parameter S or Z. A single click on S or Z will select that parameter for change and activate a blinking cursor.
- Page 23 Accessing the Serial Menu Measurements and logging tasks can be accessed via the serial port or the USB using a terminal emulator such as Tera Term Pro or HyperTerminal running on an attached computer. Commands can be sent using the terminal emulator set with the properties listed in the section of this manual entitled “Collecting Data over the Serial Port in Real Time”.
- Page 24 Collecting Data from the Analog Output The data may be logged in real time using a data logger attached to the D9 connector on the back panel of the instrument using either a voltage or current recorder or data logger. The 0-2.5 V output is measured across pins #1 (+) and #5 (ground).
- Page 25 move the cursor using the Select switch to choose the digits in the On and Off relay settings, choose a digit to change by depressing the Select switch, and rotate the Select switch to change those settings. To choose another digit to change, depress the Select switch again to remove the blinking cursor.
- Page 26 Select ppb, depress the select switch to obtain a blinking cursor and rotate the select switch to choose between units of ppb, pphm, ppm, µg/m and mg/m Press the select switch again to remove the blinking cursor, and return to the Unt menu using the left arrow.
- Page 27 up, fluctuations in photodiode voltage should be limited primarily to the last digit displayed. The lamp test also calculates an electronic offset and standard deviation of the measurement itself, displayed in the above example as 1.2 ppb for the electronic offset and +/-1.85 for the standard deviation. The standard deviation is a quantitative measure of the lamp and associated electronic noise.

Other components with a limited lifetime are the air pump (~15,000 hours), lamp (~20,000 hours) and solenoid valve (rarely fails). It is recommended that the instrument we returned to 2B Technologies if any of these components fail. Alternatively, the user may install these components at their own risk. In that case, please contact 2B Technologies for instructions. - Page 29 Table I. Troubleshooting the Ozone Monitor for performance problems.

Page 33: Calibration
An example of an ozone transfer standard is the 2B Technologies Model 306 Ozone Calibration Source. Ozone transfer standards must be certified before use in accordance with the procedures prescribed by the U.S. - Page 34 Equipment Required The equipment that is needed to carry out the calibration is commercially available, or it can be assembled by the user. Calibration using a primary ozone standard involves the generation of ozone concentrations that are simultaneously measured by a primary ozone standard and the instrument undergoing calibration.
- Page 35 Calibration Setup Preparation As indicated in the EPA Technical Assistance Document there are several tests that should be performed prior to calibration to ensure the accuracy of the measurements. These tests include: Setup check Ozone loss test Linearity check ...
- Page 36 where: R = Dilution ratio = Ozone generator flow = Diluent zero air flow E = Linearity error, in percent = Measured concentration of original concentration = Measured concentration of diluted concentration The linearity error should not be greater than 5%. If the error is greater than 5%, the accuracy of the flow dilution should be checked before assuming that the ozone monitor is not linear.
- Page 37 3. Connect the ozone monitor to the manifold on the ozone calibration setup. If a particle filter will be used in normal operation, the calibration must be performed through the filter. The manifold must be vented to atmosphere so that pressure does not build up in the calibration setup.
- Page 38 contamination in the optical setup. See the “Troubleshooting” section of the manual. 4. The slope of the line is the gain factor (S) and the intercept is the offset (Z) that need to be applied to the ozone monitor response to calibrate it to the primary ozone standard.
