All Ascott Cyclic Corrosion Test chambers feature:

  • Touch-screen, full color user control interface, employing the latest version of our highly intuitive operating software, for ease of programming and use.
  • The operating software has a very large capacity for the creation of complex multi-step test programmes, so that the widest possible range of test profiles can be accommodated.
  • The icon based control interface offers a variety of languages built-in for ease of understanding and use.
  • RJ45 communications port enabling the chamber to be wired or wirelessly connected to a local area network (LAN) for logging and remote programming via a computer running optional software.
  • A real-time, user configurable ‘clock’ to enable different test samples to be batched and have their exposure time monitored separately, with alarms to warn when a pre-set test period has been completed.
  • Touch-screen operator control interface.
  • ‘Easy Open’ pneumatically operated canopy.
  • Dry seal gasket prevents wetting operator’s clothes, etc.
  • Low loading threshold for loading and unloading.
  • Large capacity salt solution reservoir mounted on castors for mobility.
  • Calibration certificate.
  • Canopy color choice.
  • Set of sample racks.
  • Interior viewing window.
  • Consumables spares kit.
  • Easily accessible salt spray atomizer(s) in transparent hard-wearing acrylic.
  • Purge of the cabinet interior with fresh air after testing and before the chamber is opened.

Modes of Operation

Ascott CCT chambers are designed to be flexible enough to comply with as many different CCT specifications as possible. As standard they come with the ability to create 4 distinct climates:

  • Salt spray
  • Condensation humidity (wetting)
  • Air drying
  • Controlled humidity

– which may be programmed to occur in any sequence and be repeated automatically. By choosing from a wide range of optional accessories, these climates may be added to as required to further extend the number of climates and conditions that can be created.


Wetting mode  Temperature range  Adjustable from ambient to +70°C/+158°F
  Humidity range  Fixed at 95% – 100% RH
Salt spray mode  Temperature range  Adjustable from ambient to +50°C/+122°F
  Salt spray fall-out rates  Adjustable from 0.5 to 2.5 ml per 80 cm² per hour
(Option ACC01 increases fallout rate up to 5.5 ml per 80 cm² per hour)
Drying mode Temperature range  Adjustable from ambient to +70°C/+158°F
  Humidity range  Uncontrolled
Controlled humidity mode Temperature/humidity range  See graph
