SO2 Humidity Chamber

Kesternich testing simulates acid rain or industrial chemical exposure  to evaluate the relative corrosion resistance of the coating, substrate, or part itself.  Parts or panels are placed inside a specially designed chamber and are exposed to SO2 and condensation humidity before being evaluated for resistance to corrosion.

Communication port

RJ45 communications port for connection to a local area network (LAN) for logging and remote programming via a computer running optional Ascott software (ACC121).

Dry seal gasket

Dry seal gasket prevents wetting operator’s clothes, etc

S02 dispersion bar

Fully automated electronic gas dosing system.

Air distribution bar

For purging and the air drying function.

Test space illumination

The inside of the test space can be illuminated at the touch of a button.

Low loading threshold

Low loading threshold for loading and unloading samples into the chamber

Chamber Connection

The following connections can be found on the back of the chamber: Mains power lead, remote diagnostic socket - Connection to the chamber, compressed air connection, Sulfur dioxide inlet, drain for change the paraffin system, water inlet

Well-designed test room

Chamber designed with angled interior roof to avoid condensation droplets falling onto samples below.

Fully Automatic, SO2 Gas Dosing Test Chamber.

A specific volume of SO2 gas, usually 0.2L, 1L or 2L is introduced into the test chamber, the chamber temperature is increased to a predetermined level and the relative humidity is maintained at condensation levels. After a set period, the chamber is vented and the temperature is allowed to decrease to ambient conditions.

Ascott’s Kesternich chamber does not require any human intervention whilst running the tests, its fully automatic design is controlled by a state of the art control system. The Kesternich chamber is designed to meet various gas dosing test standards as listed below and can also be used as a condensation humidity chamber.

Discover the advanced user interface of the Ascott Kesternich SO₂ Humidity Chamber in action.

This video offers a detailed look at the innovative touchscreen control system of the Ascott Kesternich SO₂ Humidity Chamber. The intuitive interface allows users to easily configure and manage all test parameters — including SO₂ gas dosing, humidity control, air purging, and drainage — all fully automated.

Designed for efficiency and repeatability, the system ensures consistent and accurate corrosion testing results. Watch the video to see how effortless and effective test setup and operation can be with the latest control technology.

Product options

Guardian Angel (ACC05)

The Guardian Angel comprises a modular light alarm that can now be fitted to the top of all Ascott iP chambers. When the chamber is in daily use in the laboratory it allows the occupants of the area to see the status of the chamber visually at a distance depending on the colour of the status light:
GREEN: Everything is operating correctly.
AMBER: The chamber has a small problem which will eventually need attention but is still operational.
RED: The chamber operation has been stopped and needs immediate attention.

Logging software (ACC121)

This software allows logging of chamber variables and editing of chamber programs using a graphical interface. It also allows for remote programming, pause , start, stop. This software is suitable for logging a maximum of 3 chambers at any one time, providing all chambers are connected to the same network, either via an Ethernet hub or router.

Wall Mounted So2 Detector (ACC128 )

When working with So2 then safety is obviously paramount for all users of such equipment. We can offer a wall mounted detector that is powered by mains. The unit is to be fitted on or near to the chamber to help detect leaks proactively with the chamber or gas bottles.

Water Pressure booster (ACC61)

An externally mounted water pump that can be used in order to boost the customer fed incoming water pressure.
