With the
SK400C corrosive gas test chamber, we
have successfully integrated this corrosive gas dosing system into a CTS
climatic chamber to ensure standardised climate simulation and thus
enable reproducible induction of corrosion.
Its refrigeration technology is designed entirely with
CO₂ compressors, making it particularly environmentally friendly and
compliant with the latest version of the F-Gas Regulation.
With its outstanding performance and a test volume of 400 litres on up to 3 levels, the SK400C corrosive
gas test chamber allows you to efficiently scale up your corrosion
tests, making it one of the highest quality corrosive gas test chambers
on the market.
Simultaneous dosing of up to 4 corrosive gases
The SK400C is characterised by a removable container
made of transparent, corrosion-resistant plastic (PMMA) and can be
equipped with up to 4 individual dosing lines. This enables both
corrosion testing with individual gases and the simultaneous dosing of
up to 4 corrosive gases. The CTS climatic chamber can also be used
flexibly for other tests by removing the PMMA container.
Our corrosive gas dosing system can be easily adapted and integrated
into different climate chambers of various sizes. Thanks to this
adaptability, we can offer you extremely versatile solutions that can be
customised precisely to your specific requirements and the conditions
of a wide range of test environments.

Key facts
- Ideal results thanks to high-precision corrosive gas dosing using a high-quality mass flow controller
- Ideal injection of the corrosive gases in the carrier gas free jet
and homogenization by diffuser expansion before entering the test
chamber. As a result, even the smallest concentrations in the range of
10 ppb are homogeneously mixed and brought into the test chamber in the
specified concentration.
- Continuous monitoring of the air exchange rates and gas
concentrations by three independent parameters with automatic switch-off
when the process parameters are exceeded. These must include the
recording and control of the test chamber internal pressure, the carrier
air inflow rate, the supply air rate of the corrosive gas dosing and
the fan characteristics in relation to the speed
- Regulation of the air exchange rate by means of a flow sensor at the
inlet of the corrosive gas test chamber. This ensures correct
concentrations in accordance with the corresponding standard when the
corrosive gases enter the test chamber, preventing concentrations from
increasing above the standard value.
- Software specially developed for the application of corrosive gas
testing, which guides the user through the individual process steps in a
user-friendly manner
- Clear view of the test material thanks to high-quality acrylic glass
windows (polymethyl methacrylate) that enable transparent observation
- Compliance with industry-leading test standards such as IEC
60068-2-60, IEC 60068-2-42/43 and others to ensure reliable test results
Performance characteristics
- Possible test gases: hydrogen sulphide (H₂S), sulphur dioxide (SO₂),
chlorine gas (Cl₂) with carrier gas N₂, nitrogen dioxide (NO₂) with
carrier gas synthetic air, and others
- Dosing of up to four corrosive gases with 4 corrosive gas dosing lines in the range 1-100 ml/min
- Pressure monitoring as an integrated safety device for reliable operation
- Connection for gas sampling for further analysis
- Testing of the corrosive gas concentration optionally possible with dry air or nitrogen
