Product Features
Sample transfer type structure
By switching between high and low temperature chambers in a short period of time, specimens are subjected to instantaneous temperature changes to realize highly reproducible cold thermal shock testing.
Defrost-free operation
The unique mechanism enables continuous operation of more than 1,000 cycles, eliminating the need for test interruption due to defrosting.
Independent use of high and low temperature tanks
Each chamber can be used as an independent chamber and can be utilized not only for thermal shock testing but also for independent high or low temperature testing.
Robust construction
The test chamber is made of highly corrosion-resistant stainless steel to maintain stable performance even with rapid temperature changes and long-term operation. Product Features
operability
- Large observation windowWidth: 355 mm x Height: 355 mm. all models are equipped as standard for high visibility.
- Sample basket with meshSafety is improved by preventing specimens from falling.

- 7-inch color TFT touch panelIntuitive operation screen with full Japanese support.
- WEBSeason®.Remote access from smartphones and tablets, with chart preview function.
- S!MPATI®.: Up to 99 test instruments can be centrally managed, and data can be documented and edited (optional).
- CSV output: Test results can be saved on a USB memory stick and analyzed with common spreadsheet software.
Environmentally Friendly
- Adoption of low GWP refrigerant R449AGlobal warming potential is reduced to about 1/3 that of conventional refrigerants.
- Compliance with European F-Gas Regulations: Can be used safely even after 2030
- economical modeEnergy savings of up to 37% is achieved by controlling the unused tanks without heating or cooling them.
- CO2 emission reductionContributing to sustainability by reducing environmental impact
