1Preface
CO2-O2-UNIT-BL [0-10; 1-18] is a Digital CO2/O2Controller that mixes CO2, N2 and Air to the desired
concentration in the CO2 range 0-10% and O2 range 1-18%.
It features a long life Non Dispersive Infrared (NDIR) dual wave length CO2 detector and a long life O2
optical sensor to ensure a high accuracy on the gas composition.
CO2-O2-UNIT-BL [0-10; 1-18] is operated via the OKO-TOUCH touch screen control panel (to be ordered
separately). OKO-TOUCH features on-board memory for data logging and mini-USB port for data download.
In addition data logging is possible via SMART-BOX, via DATA-LOG Okolab software and via following
third-party Imaging software: LASX 2.0, NIS-Elements, SlideBook, MetaMorph and MicroManager. Macro for ZEN
Black software is available upon request.
Okolab Bold Line controllers are also capable to receive TTL input (requires to order separately TTL-
CABLE).
CO2-O2-UNIT-BL [0-10; 1-18] allows easily operating without N2 by setting the maximum Oxygen % value
from the Touch Screen.
CO2-O2-UNIT-BL [0-10; 1-18] connects to any Okolab Bold Line T controller. In this case, a single OKO-
TOUCH operates both, the Bold Line T controller and CO2-O2-UNIT-BL [0-10; 1-18].
CO2-O2-UNIT-BL [0-10; 1-18] is also compatible with Okolab Active Humidity Controller to control output
gas Relative Humidity and with Okolab air pump OKO-PUMP-BL, which enables to use background air as a
convenient alternative to the compressed air.

3Safety Notes
In order to achieve maximum performance and to ensure proper operation of your new equipment, please
read carefully the following safety notes and the instructions. If you have any question, please contact Okolab.
−The equipment must only be used as intended and as described in this Manual.
−Equipment should be operated only by technically qualified personnel.
−Do not start up the equipment if some of its parts are damaged.
−This instrument is not intended for use in locations subject to flammable or explosive gases.
−Transport the equipment with care.
−Equipment and its internal parts can be damaged by dropping and by shock.
−Not following these instructions can result in damage or breakdown of the device and its
accessories.
−The products labels can be found on the bottom panel of the Main Box.
−Do not disassemble any part of the system.
−Do not use a volatile solvent such as paint thinner to clean the instrument, because
deformation or discoloration may occur.
−Use a soft, dry cloth to remove stains from the instrument.
−Do not exceed voltage indicated in this manual and on the product label.
−Avoid excessive induction noise, static electricity and magnetic fields.
−Do not expose this instrument to rain or moisture.
−Do NOT go in close contact with or breathe any gas stream whose composition is different
from that of ambient air.
−Prevent throttling and kinking of tubing.
−Check tubing time to time for possible material usage.
−Check that all tubing are well inserted into the connectors so they cannot slip off
−This device is not designed for use for medical applications.
−Install safety valves and adequate pressure regulators on gas lines before CO2-O2-UNIT-
BL [0-10; 1-18] input connectors.
−Power cord of unit should be unplugged from electrical outlet when left unused for a long
period of time.
−PRESSURIZED GAS. Secure all connections with hose clamps. Never exceed the input
pressure limit of 1.5 bar. Bleed all lines before disconnecting. Wear safety goggles if needed.
If pressure regulators are not within sight and reach, make sure at least one shut off valve
is within reach.
−LOW OXYGEN ATMOSPHERES. Never enter a room or enclosure which has a low oxygen
atmosphere because of severe danger of suffocation. Only operate in well-ventilated room.
A small amount for carbon dioxide gas leaks continuously out of the instrument and should
never be allowed to build up in the room.
−VENTILATION. Unit should be situated so that its location or position does not interfere
with proper ventilation. Neither the gas mixer nor stream destinations should be in poorly
ventilated areas.
−Unit should be situated away from heat sources such as open flames, radiators, heat
registers, stoves, or other appliances or processes that produce heat.

−Do not start up the equipment if the supply cable is damaged.
−Connect the equipment only to grounded mains power socket.
−Do not disconnect cables while in operation.
−Do not open the unit. Do not remove cover or back.
−Prevent metal fragments or lead wire scraps from falling inside instrument to avoid electric
shock, fire or malfunction.
−No user serviceable parts inside.
−Unit should never be used where it can fall or be pushed into water.
International caution symbol marks this device. It is important to read the “Safety
Notes” before installing, using and commissioning this device, as the notes contain
important information relating to safety and EMC. Not following these instructions
can result in damage or breakdown of the device and its accessories
We reserve the right to make technical variations.
IN NO EVENT SHALL OKOLAB S.R.L. BE LIABLE FOR ANY DIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES OF ANY NATURE, OR LOSSES OR EXPENSES RESULTING FROM ANY DEFECTIVE PRODUCT OR THE USE
OF ANY PRODUCT.
