Operational Functions - Cooled Incubators

Programmable 3-step operational functions
with microcomputer control

Program input is simple and the steps during each operation
are indicated via the LCD display. This incubator accommodates
a range of diversied experimentation requirements, and
is ideal for experimentation during night time or holidays,
experimentation that requires settings to be changed, and
microorganism culture and preservation. Constant operation
mode without step operation is also available.

3 Step Repeat Operation

Temperature (T1, T2, T3) and Time (H1, H2, H3) are set. Then, limited
repeating operations (from 1 to 99 times) or continuously repeated
operations are conducted. After a limited repeating operation has
been completed, constant operating temperature T0 is retained.
Application: Optimum for repeated experiments in which 3 different
elemental temperatures and times are combined.

The MIR Series accommodates a wide range of temperatures

High-precision Temperature Environment

SANYO Refrigerated Incubators incorporate a high precision
microprocessor temperature control combined with a heater P.I.D.
and compressor ON-OFF system. This system has a feed forward
function that inputs the operating conditions of the compressor
beforehand, ensuring accurate temperature control for the chamber.
In a wide temperature range from -10°C to 60°C, the heater P.I.D.
exhibits temperature uctuation up to 0.2°C, and the Compressor
ON-OFF controls precisely ±1.5°C. In addition, the uctuation of
temperature uniformity in the chamber is within ±0.5°C, allowing a
full range of precise experimentation from microorganism cultures
to various types of incubation and testing.

Energy Savings

In addition to a microprocessor-controlled high efcient heater
output and compressor ON/OFF, a renewal control program and
low heat-emission inner chamber fan are newly adopted that
allow high-energy saving operation over a wider range of ambient
environments.

Foamed-in-place Rigid Polyurethane Insulation

HCFC-free foamed-in-place polyurethane is used for the chamber
because of its high thermal retention and energy saving properties.

Triple-pane Glass Observation Window plus
Programmable 15W Fluorescent Lamp

An easy-to-observe triple-pane glass observation window and
15W uorescent lamp are provided for sample observation during
experimentation. When observation is not required, an optional light
shielding plate (MIR-154/254) can be easily attached. The MIR-554
has an observation door included.

Alarm and Security System to Protect
Sample Safety

Automatic Setting Temperature Alarm

When the chamber temperature deviates more than ±1 to ±5°C
(user selectable), all digits of the digital indicator ash. Fifteen
minutes later a buzzer will sound. This system also automatically

allows programmed operation or setting value changes.

Independent Over-temperature Protection Device

This incubator incorporates an excessive temperature prevention
circuit that protects experimentation materials in the rare event
that a temperature abnormality does occur. Isolated from the
main circuit, this exclusive circuit and sensor operate even if the
temperature sensor or microprocessor malfunction, activating
an exclusive lamp and buzzer notication. This system turns off
the heater and chamber fan motor when over temperature is
detected (setting temperature range: 15°C~65°C), and turns off
the compressor when under temperature is detected (setting
temperature range -15°C to 20°C). Remote alarm contacts are
provided for monitoring alarm from a remote location.

Programmed Memory Back-up Mechanism

Should the power source be interrupted due to power failure or
other event, programmed data remains stored in memory semi­permanently. When the power source is restored, operation can be
continued according to the predetermined program.

Automatic Return Buzzer Switch

After an power failure occurs, the alarm buzzer automatically
switches to the ON mode, even if the operator forgets to return
the alarm buzzer to the ON mode, thus ensuring safe and secure
operation.

Key Lock

A key lock switch is provided so that settings may not be changed
unintentionally.

Auto Return Mechanism

This mechanism automatically returns the chamber temperature
indicator to its normal indication when the control key is not
operated for approx. 90 seconds at each setting mode. Thus, normal

operation is ensured even if the operator forgets an operational

procedure during setting.

Trouble Monitor (Self Diagnostic Function)

Should a malfunction occur, the location of the malfunction can be
digitally indicated, allowing quick operator response.

3 Step to Constant Operation

Temperature of T1, T2, and T3, correspond to times H1, H2, and H3,
respectively. Then, constant operation temperature T0 is retained.
Application: Optimum for experiments that require consistent 4-step
temperature increases and decreases.

2 Step to Repeating Operation

Using a temperature T1 and T2, operation is repeatedly conducted
using time H1 and H2. Application: Optimum for day and night cycle
operations of plant material or quality testing for chemicals, foods
and samples.

2 Step to Constant Operation

With a temperature of T1 and T2, operation is conducted using time
H1 and H2. Then, constant operating temperature T0 is retained.

1 Step to Constant Operation

With a temperature of T1, operation is conducted using time H1.
Then, constant operating temperature T0 is retained.
Application: Optimum for automation and labor savings while
performing bacteria inspection from culture to preservation, and from
preservation to culture.

Incubation & Testing

MLR-351H Environmental Test Chambers with Humidity Control

The microprocessor P.I.D. and refrigeration capacity control
minimizes temperature uctuations and thereby improves
temperature control. This allows precise experiments plus energy
and electricity savings.

Programming of temperature, light, and humidity can be used for
small plants, environmental tests, algae, drosophila, etc.

Easy calibration of temperature and humidity can be calibrated
easily through the control panel. Small lightweight, high molecular
membrane-type humidity sensor also boasts a high degree of
accuracy and reproducibility.

Graphic LCD panel with pop-up menu function on control panel
provides visual display of operation and allows intuitive operation.

Versatile Environmental Test Chamber

• Graphic LCD provides easier operation

• Programmable temperature, lighting and humidity function

• Microprocessor P.I.D. temperature control

• Data logging function

• Easy calibration through controller

• Small lightweight, high molecular membrane-type humidity sensor

Feature and Benefits

Microprocessor P.I.D. controls temperature and humidity to create
the optimum environments for various applications.

Programmable Temperature Function can operate 12 step programs
x 10 patterns which can be stored, select a clock or timer mode,
multiple programs can be ‘connected’ (join mode), and a starting day
and time of operation can be programmed.

Automatic Data Logging of Operational Data of approximately two
weeks (6 minute intervals) can be automatically recorded. The
data can be viewed on the control panel. The data can also be
transmitted to a PC via RS-232C, interface board (MTR-480 required)

Technology and Applications

The wide variety of temperatures, humidity and lighting patterns
that are essential in research and environmental studies can now be
accurately reproduced and controlled.
