Preface

CO2-UNIT-BL

is a Digital CO2 Controller that mixes CO2 and Air to the desired concentration in the range

0-18%. It connects to any Bold Line T controller and can be operated through the same intuitive touch screen
interface, OKO-TOUCH.

The

CO2-UNIT-BL

features a long life Non Dispersive InfraRed (NDIR) dual wave length detector to

ensure a high accuracy on CO2 concentration and a flow rate sensor to regulate output flow rate.

The

CO2-UNIT-BL

is 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 compressed air.

The

CO2-UNIT-BL

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).
