- Intensive exposure to light and heat - Caustic or high solvent vapours. Any work done on the inside of the instrument must be carried out by AQUALABO or by technicians authorized by 3.4 PACKAGING The NEON_OPTOD Oximeter is shipped in packaging to protect it during transport. It is essential to keep the original packaging as well as the inner packaging so as to ensure optimal protection of the device from any impacts in the event of further transport.
The NEON portable housing also contains an Atmospheric Pressure sensor for automatic compensation of the Oxygen parameter in mg/L. 4.3 MAIN FUNCTIONS OF NEON OXYMETER. The NEON OPTOD sensor unit, specifically designed to measure dissolved oxygen in the aquaculture field, offers the following features: - Automatic recognition of the Oxygen sensor, - Simultaneous display of the 3 parameters (Temperature, Oxygen % Sat, Oxygen mg/L);...

NEON_OPTOD 5.3 DESCRIPTION OF STAINLESS STEEL AND TITANIUM OPTOD SENSOR. The OPTOD dissolved oxygen sensor uses luminescence-based optical measurement technology and measures reliably and accurately. Without consumables or maintenance, the OPTOD sensor provides an immediate return on investment. The only action required is the replacement of the oxygen active pellet every two years. Since it does not consume oxygen, the OPTOD sensor can be used on all types of media even when low water flow is very low.
NEON_OPTOD 6. START-UP 6.1 POWER SUPPLY 6.1.1 T YPE OF BATTERIES PERMITTED The measuring unit comes with 3 AA-size alkaline batteries. The user should never combine batteries of different types. Three AA-size NiMH batteries, 1.2 V (VARTA type) may be used. 6.1.2 C HANGING BATTERIES The 3 used alkaline batteries (AA) must be replaced in a perfectly clean and dry room so as not to stain the inside of...
NEON_OPTOD 6.3 SETTING 6.3.1 M AIN SCREEN The main screen displays the following in real time: - Parameters measured by the Oxygen sensor along with their units of measure: Temperature (°C), Oxygen in mg/L, Oxygen in % saturation. A ZOOM function allows you to view a parameter in a larger format. - A series of icons (at the bottom of the screen) to track the state of charge of the batteries, measurement stability, data recording activation as well as wifi activation for data transfer to a PC.
NEON_OPTOD 6.3.2 G ENERAL The "GENERAL MENU" screen gives access to the Calibration, Registration and Preferences settings (date/time configuration, NEON laptop and sensor information, standby time delay configuration, language selection, RESET functionality in settings). CALIBRATION RECORDING PREFERENCES To access the desired menu, move the cursor using the up and down arrows and confirm the selection with the “OK” key.

NEON_OPTOD To access the desired menu, move the cursor using the up and down arrows and confirm the selection with the “OK” key. To return to the previous screen press the ESC key. GAIN only calibration: For the OPTOD sensor, the gain alone can be set by adjusting to 100% the air saturated with water vapor. In theory this state can be achieved by placing the sensor in water-saturated air (for example directly above a water surface) or according to the illustration below: Fill the bottom of a vial with water and put the sensor just above the water.
NEON_OPTOD Having first cleaned the sensor (see ) it is immersed in a water-sulphite solution (concentration of Cleaning section 8.1 sulphite <2% by weight, 2 g max. in 100 ml of water) to determine the zero point (saturation 0%). Mix the solution using the sensor to decrease oxygen saturation faster (oxygen attached to the DODISK must be consumed).
NEON_OPTOD BAROMETER ---- 995 hPa The atmospheric pressure can be adjusted to the 450-1200 hPa range. Adjust the atmospheric pressure measurement using the up/down arrows (the entry changes to white) and confirm with the “OK” key (the entry then changes to green). To return to the previous screen, press escape (ESC).

NEON_OPTOD 8. 8. OPTOD SENSOR MAINTENANCE The sensor must always be kept clean, especially in the area around the membrane and optical part. The presence of a biofilm on the membrane may result in measurement errors. A soiled membrane must be cleaned with hot soapy water. A soft sponge can be used for cleaning (do not use an abrasive sponge).
