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.
