4Preface
LEO (see Figure 1 for front and rear view of LEO) is a handheld meter for IVF Applications, allowing
measurement of CO2-O2 gas composition, temperature, relative humidity, gas flow of the high-top and bench-top
incubators, by using multiple sensor modules.
The CO2-O2-MODULE is embedded into LEO, and it is included standard. It measures, with a high accuracy,
the CO2-O2 volume concentration in the unit of %, and CO2-O2 partial pressure in the units of mbar, psi and KPa.
Other (external) sensor modules that can be connected to LEO’s connection ports are: T1-MODULE, T2-
MODULE, CO2-PPM-MODULE, HUMIDITY-MODULE, FLOW-RATE-MODULE. All sensor modules are calibrated by
using traceable standards, and store the calibration data in the internal memory. The sensor modules can be
delivered with traceable or accredited calibration certificate, and sent to Okolab for re-calibration. Moreover,
sensor calibration can be performed by using LEO intuitive user calibration routines.
LEO works in Diffusion Mode when the gas to be sampled is pressurized and in Aspiration Mode when it
works at atmosphere pressure, sucking the gas from the incubator by an internal pump. In both cases, if the gas
inside the incubator is humid, prior de-humidification with the Moisture Trap (included standard with LEO) is
needed to retain water molecules.
LEO can improve the CO2 and O2 reading accounting the water content of your incubator by use Wet
Mode. The temperature and relative humidity (RH) values of your incubator must be entered.
LEO can perform both single measurement and extended time logging, storing the data in its local memory.
LEO allows organization of the stored data, associating a label to each device. You can store up to 40 devices labels.
The stored data to be downloaded through the micro USB port, and analyzed by using the free LEO DATA IMPORT
Excel Macro.
LEO features a user-friendly 4.3” touch screen interface.
