    Refrigerated Incubator / Environmental Testing Chamber - Panasonic MIR-254 Features:

    The MIR-Series incorporates an 8-bit microprocessor controller for heat and refrigeration control;0.2 deg C. Programmable models include three-step functions useful for investigations involving microbiology, plant cell biology and more.

    Precise Temperature Control For accurate, Repeatable Conditions

    • High precision microprocessor controller combined with a heater P.I.D. and compressor On-Off system.
    • Feed forward function inputs compressor operating conditions beforehand, assuring accurate temperature control.
    • Wide temperature range settable from -10 deg C to +60 deg C with precise temperature control to +/-0.1 deg C.
    • Chamber temperature uniformity;0.5 deg C

    Energy Saving Operation

    • Microprocessor control operates heater and compressor functions for optimum automatic operation.
    • Control sensitivity to ambient and load conditions minimizes power requirement.

    CFC-Free Foamed-In-Place Rigid Insulation

    • High thermal retention
    • Energy saving
    • Environmentally safe

    Triple-Pane Glass Window, fluorescent Lamp

    • Allow sample observation during process.
    • Light shielding plate (MIR-153/253) can be attached to block ambient light

    Alarm and Security System, Automatic Setting Temperature Alarm

    • Activates automatically if chamber temperature deviates more than +/-2.5 deg C from setpoint
    • Digital indicator flashes during warning
    • Audible buzzer sounds after 10 minutes
    • Accommodates programmed operation or setpoint changes

    Independent Over and Under-Temperature Protection

    • Isolated from main circuit, an exclusive and independent sensor functions even if sensor or microprocessor continuity is interrupted
    • Activates audible and visual warning in case of deviation
    • Over temperature function:
      • Turns off heater and chamber fan motor during alarm condition
      • 15 deg C - 65 deg C
    • Under temperature function
      • Turns off refrigeration compressor
      • -15 deg C to +20 deg C
    • Remote alarm contacts provided for connection to external alarm system

    Programmed Memory Back-Up System

    • Retains programmed data for approximately 5 hours if power is interrupted.
    • When power is restored, operation continues according to pre-determined program

    Automatic Return Buzzer Switch

    • Automatically switches to ON mode after alarm condition
    • Minimizes chance of human error on alarm reset.

    Control Key Lock Switch

    • Prevents unauthorized change in setpoints or programs
    • Includes multi-position switch activated to ON or OFF by control key

    Control Key Auto Return

    • Automatically returns temperature indicator to normal indication when control key is not operated for approximately 90 seconds.
    • Assures normal operation, minimizes chance of human error if operational setting is not re-established.

    Self-Diagnostic Function

    • Digitally indicates system error
    • Allows quick operator response

    Refrigeration System

    • Panasonic hermetically sealed compressors
    • CFC-free refrigerants
