Large Size Series

Test the reliability of your products in different temperatures and humidity. The Constant Temperature & Humidity Chamber allows you to keep the desired temperature and humidity at all times without any effort, saving you time and energy. Constant temperature and humidity chambers simulate the real-world thermal conditions of a product in use. It is especially suited for testing of devices with electric or electronic components, and the materials that come into contact with them. The Excellent Series chambers can maintain temperatures from – 40°C to 150°C and relative humidities from 20% to 98% RH depending on the model.

Low power consumption

Efficiently built chambers that make the most of every watt.

High Performance

Best in class performance with commendable efficiency.

Low Noise

Quiet operation ensures a tranquil surrounding.

Compact Size

Correspond to large size test sample.

Expand the test chamber dimension and enabled to correspond large size sample examination such as large size display (ex. LCD panel) or solar power module.

Correspond to humidity control function

Adopting 2 refrigerating cycles of inverter control and constant speed control.
At low load conditions, saving electric power by controlling refrigerate machine to test condition.

Improvement of usability

No need of wick change by adopting capacitance type humidity sensor. Also, illumination up and energy-saving is coexistence by adopting LED light.

Corresponding 2kW heat load

Correspondence of allowance of heat load to 2kW heat load
at 40℃/90%RH testing condition (at High load mode). Corresponding for tests with electric conduction materials or
with heat load.

High capacity testing chamber

By owning chamber capacity of 3,780L and 4,780L to be able to correspond large size material test such as solar cell module, display, rechargeable battery, or others.

Achieving Solar cell module evaluation test standard

Corresponding specific condensation freezing test in the IEC 61646(Edition2.0) which is the evaluation test standard for solar cell module

Refrigerate control

Reducing power dissipation by controlling refrigerating ability by matching refrigerating machine to operating condition at low necessary of refrigerate ability in high temperature (humidity) testing condition

Energy saving performance

Inverter control of scroll compressor（ 600W）performs great energy saving effect at all the area of temperature &
temperature/humidity control range.

Defrosting function

Cyclical defrosting function by setting the operation time

  • When the temperature in the chamber is
    less than 5℃, heater will warm the inner chamber to required temperature to defrost.
  • When the temperature in the chamber is
    over 5℃, refrigerator will suspend and
    defrost.

Humidification delay function

Function to prevent sample from dew condensation at the temperature / humidity rising time, by delaying the humidification start for an optional set time (1 to 120 minutes) after the dry-bulb rise to the required temperature.

USB memory saving function

Saving the trend-graph data to USB memory is available. This is the function which enables USB memory to save the data (measured temperature, measured humidity) shown on the trend-graph of LCD operation panel as CSV file format.

Data log Function

When the operation stops by alarm for abnormal detection, this feature saves the data (the operating situation just before the trouble has occurred) to USB memory. Collecting the data just before the operation-stop enabled user to do trouble analysis.

Operation mode selective function

While operating the program, the user can choose the settings of operation mode by each step. (Choice of Energy saving mode, High load mode) For example electric conduction, a setting
change of the device ability
according to the test pattern is possible.

Unit Control Panel

Color LCD Touch Panel

The color LCD touch panel is adopted so that setting and controlling of the unit will be simple only by touching the displays. The color LCD offers clear view and the system is supported for diverse functions in operation control.

Program name input function

At this function, you may input a program name. Program name can be input by using alphabet, number, and
symbols (!”#%&’()@:,.=+-*/?_) for 14 words (maximum).

Various types of communication interface

By using communication interface, unit is being enabled to external control on operations and measurements from a connected computer or user’s original system unit.

Combined-program operate function

At this function, you may operate 2 or more programs continuously (or by combination). Up to 5 combined programs can be operated at maximum.

Various types of communication interface

By using communication interface, unit is being enabled
to external control on operations and measurements from a connected computer or user’s original system unit.
