Salt Spray Chambers

Ascott salt spray cabinets and chambers – one of the world’s most modern and most versatile salt spray corrosion test systems – and with design, ergonomics and quality that’s in a class of its own. Chambers to cover every testing requirement from continuous salt spray test through to condensation humidity and modified tests.



Ascott Analytical Salt Spray Chambers

Key Features

Six model sizes:

  • 120 Ltr (4.2 cu ft)
  • 450 Ltr (15.8 cu ft)
  • 1000 Ltr (35.3 cu ft)
  • 1300 Ltr (45.9 cu ft)
  • 2000 Ltr (70.6 cu ft)
  • 2600 Ltr (91.8 cu ft)

Two specification levels:

  • StandardStandard models meet the requirements of basic, continuous salt spray tests conducted at a single temperature only, such as ASTM B117 and similar international test standards, and may be used with pH neutral salt solutions (NSS) or those acidified by the addition of Acetic Acid (ASS) or Cupric Acid (CASS).
  • PremiumPremium models can perform the same basic salt spray tests, but in addition are equipped with extra features which enable them to undertake ‘modified’ tests such as those defined in ASTM G85. Here conventional salt spray is often combined with one other climate, in a two-part cycle, to accelerate the test. For example: salt spray and condensation humidity (SWAAT) or salt spray and drying (PROHESION) or salt spray and SO2 testing.

All Ascott corrosion test chamber models feature:

  • 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 floor standing salt solution reservoir.
  • 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.

Additional features of Premium Salt Spray Chambers:

  • 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.


Standard and Premium model specifications to cover every need:

Standard chambers feature all the facilities described in the chamber key features and have:

  • alpha-numeric messaging interface for programming and control commands
  • hours run counter

Standard chambers cover the requirements for continuous salt spray testing to ASTM B117 & similar international salt spray test standards.

Premium chambers feature all the facilities of the Standard models and:

  • touch screen, menu driven programming with graphical logging actual & set conditions
  • user programmable for ‘modified’ salt spray tests

For Salt Spray Testing to ASTM B117, ASTM G85 (Annex A1, A2, A3, A4* & A5) & Humidity Testing to ASTM D2247 & similar test standards.
