LMS Series 4 cooled incubators are temperature controlled cabinets with fan assisted air circulation via a pre-mixing chamber. The units have a stainless steel exterior, stainless steel lined interior with polyurethane foam insulation, and feature a door lock and magnetic door gasket. Corrosion resistant inner chamber is easy to clean, disinfection procedures are detailed in the user manual.

• Units feature automatic defrost
• Easy to use controls with digital display of actual temperature (and set point for programmable models)
• Hermetically sealed refrigeration system, and suppressed RF and TV electronics
• Safety features include variable over-temperature alarm, safety cutout preset at 70 °C and refrigeration isolation switch
• Full PID heating control to ensure stable internal temperature

Controls are recessed in the control panel, to avoid accidental alteration. Full PID heating control, indicators for mains and high temperature safety cutout. They are ideal for studying growth patterns of plants and insects, BOD tests, seed germination, tissue culture, enzyme testing and fruit fly culture.

The programmable option for LMS Series 4 cooled incubators (denoted by NP) is designed to offer the highest functionality and enables the user to set up and run complex processes relying on accurate temperature control. The programmer function is able to control applications needing set point changes over time, e.g. ramp changes where a gradual rate of change can be set or step changes which are instantaneous. These can be separated by soak periods during which the process is held at a constant value. Each individual time interval of the program, or segment, together with its associated moving set point value, can be stored as a unique program. Via use of 'event outputs' control of interior illumination and/or alarm function is also available. At the end of a sequence, a program can be arranged to repeat (or loop), either a specified number of cycles, or continuously. For safety reasons, three modes of recovery from power failure are available. These either automatically restart the program from the beginning, continue it from where it stopped or hold it, waiting for a user restart. Finally, chart recorder, data logging and configuration software for Windows is available as optional extras. This software is designed to operate to program all functions of the controller and to data log the recorded process signals, including chart recorder for on screen viewing of trends, virtual instrument display, on screen alarm displays and remote set point adjustment.

'A' denotes dual temperature cycling models, 'NP' denotes programmable models. The only difference is the programmable controller, all other specifications are the same for all types of models.

* Please note that with the maximum number of shelves fitted in a cabinet, there is only a 20 mm gap between each shelf.
