Control system
The colour LCD touch screen display allows the user to easily see operating conditions and to alter
settings through icon based menus.
Software controlled PID loops constantly monitor temperature and CO2 values, making automatic
adjustments to keep the chamber atmosphere within limits.
The controller is equipped with a built in feature that logs incubator data directly to a removable SD
card. This data is in Excel format, making it easy to view with a PC.
Section 7
A RS232 serial port is fitted as standard. This allows you to connect the incubator to a PC so that you
can remotely access the SD card data. PC software is required to do this. Contact your dealer or LEEC
directly for advice.
Other optional communication options are Ethernet PC interface and 4-20mA retransmit.

is measured and controlled using a highly accurate infra-red sensor. This sensor remains
practically drift free between calibration periods.
The sensor is not mounted within the chamber; instead a small pump passes the chamber atmosphere
through the sensor.
The sensor does not have to be removed during high temperature sterilisation.
