CO2- Incubators- Value Addition
Automatic sterilisation, A multifunctional, fuzzy-supported PID process controller, with permanent
performance adjustments and integrated self-diagnosis system, guarantees absolutely reliable
temperature control and realistic conditions for perfect environment simulations.
Temperature range 20 °C (at least 5 °C above ambient) to 70 °C with a display accuracy of 0.1 °C
Digital CO2 controller with precise infrared absorption measurement system (NDIR) with automatic
zeroing
Adjustable CO2 concentration 0.0 - 20.0 %.
Simultaneous display of all parameters, such as temperature, CO2, humidity, weekday and time
information
Visual and acoustic alarm in case of over-/undertemperature and excess/lack of CO2, if door is opened
or if gas bottle is empty.
Ensures perfect and absolutely reliable temperature control and the highest process safety.
Multiple overtemperature protection, An adjustable over/under temperature controller takes over control
in case of failure at a preset temperature.
Automatic Safety Function(ASF) - a unique safety function - for over- and undertemperature
automatically following the setpoint in a freely selectable tolerance range.
2 high-grade platinum temperature sensors Pt 100 in a 3-wire circuit (for stable long-term transmission of
measurement signals) communicate with each other and ensure uninterrupted error-free temperature
control at constant working temperature.
Digital programme control (programmable to the minute) for temperature profiles consisting of up to 10
ramps
Weekly timer programmable to the minute.
Function signals for stand-by, operating mode, heating and over/undertemperature Internal memory with
1024kB to save temperature and error states, with timestamp to the minute
Serial printer interface for printout of log data in thermal or dot matrix printer.
