Lab & Pharmacy Refrigerator - Refrigerated Incubator / Environmental Testing Chamber - Panasonic MIR-254

Refrigerated Incubator / Environmental Testing Chamber, model MIR-254, manufactured by Panasonic incorporates an 8-bit microprocessor controller for heat and refrigeration control to +/-0.2 Deg C, precise temperature control for accurate, repeatable conditions and CFC-free foamed-in-place rigid insulation. The automatic setting temperature alarm activates automatically if chamber temperature deviates more than 2.5 Deg C from setpoint. The digital indicator flashes during warning.

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
  • fin and tube type evaporator
  • Manual start defrost, automatic finish


    MIR environmental test chambers/refrigerated incubators are ideal in testing applications such as:
  • Industrial testing in the electrical, machinery, textiles industries
  • Chemical testing e.g., storage, stability, acid/alkali, durability
  • Food industry for packaging, quality control and stability
  • Testing for waste water, BOD, soil testing
  • Microorganism culturing
  • Germination experiments

Optional Accessories

  • MIR-S154SB
  • Key Mounting Plate: MIR-LP
  • Lighting addition kit: MIR-LP15
  • Light shading plate for glass: MIR-154BP/MIR-254BP
  • Chart Recorder: MTR-C958
