Corrosion Testing Apparatus, Model 618

Testing Apparatus to carry out tests in altering climates as well as various salt spray and condensation water tests

Corrosion chamber inclusive interface for connecting an Air Conditioning Unit

In connection with preparatory treatment techniques and new materials, coating systems have achieved a high technical level. In addition, growing working requirements and environmental aspects are leading to further improvements of the coating systems.
Therefore corrosion tests for quick quality monitoring and examination of weakest points are now as before indispensable.
All corrosion testing instruments of the 618 series are „Made in Germany“. The test chambers are made of special resistant glass fibre reinforced plastic and are suitable for low-temperature cycles (down to -40 °C) and dry heat (up to +70 °C).
The salt spray cabinets are opened pneumatically, and therefore both hands can be used to handle the test samples. The ergonomic design of the combined cabinet/chest shaped instrument enables a very user- friendly placing in of the test samples.
Different sample holder are available as accessories. All relevant test parameters are entered and read using a “Full Color Touch Panel“ with multilingual menu navigation.
By simply touching the display the required functions can be initiated. The graphics display indicates the set and the actual value, shows graphically the course of the last 72 hours.
Via touch-screen operation the user can store up to 40 main programmes, which can each consist of 50 individual steps. Therefore tests in varying climatic condition with differing specifications from the automotive standards can be pre-programmed.
Furthermore, the basic instrument is equipped with a humidity regulation function, which allows the regulation during tests from ambient conditions up to 95 % relative humidity.
The actual temperature as well as the air humidity are displayed both graphically and numerically.
The 618 series are equipped with a control unit for the humidity for tests from ambient conditions up to 95% (+/-5%) relative humidity and up to a mximum temperature of 50 °C. During salt spray tests the humidity sensor removed pneumatically from the test chamber.



The communication between test chamber control and PC will be realised by an Ethernet RJ45 communications port. This port is also used for data acquisition of test chamber temperature, humidifier temperature, relative humidity, spray pressure, etc.

The quantity of test solution is adjusted by means of the infinitely variable spray pressure and the dosing pump. This optimises the quantity of test solution proportionally to the required salt spray precipitation rate.
The control and display instruments of the test apparatus are ergonomically designed and clearly arranged so that only one glance is sufficient to inspect and act immediately if necessary.
The dosing pump (peristaltic pump) is mounted on the outside of the test instrument (rear) thus enabling an easy check and exchange of the squeeze tube.
A separate reservoir (semitransparent) for the absorption of approx. 200 l spray solution is included in the scope of supply. For simple level control the tank is equipped with float switches.

All versions of the 618 series can be combined with a Compact Air Conditioning Unit to cool the test chamber (all testers are already prepared for the connection of an air conditioner as standard.)

Depending on the application the following versions are available:
  • Compact Air Conditioning Unit for cooling the test chamber down to -20 °C and for the humidity control between 30% and 95% rel. humidity at +25 °C, for corrosion cycling tests, eg. according to VDA 233-102
  • Compact Air Conditioning Unit for cooling the test chamber down to -40 °C and for the humidity control between 30% and 95% rel. humidity at +25 °C, for corrosion cycling tests, eg. according to VDA 233-102

The specified data are valid for installation in rooms with standard ambient conditions 23/50 (DIN 50014 / ISO 554).
In non-standard ambient conditions, we recommend to use Compact Air Conditioning Units as split version.
Various optional accessories are available for additional control functions of the corrosion test apparatus 618
The test apparatus ready including the interface for connection to the Compact Air Condition Unit.
Besides the usual applications such as salt spray test and cyclic corrosion tests, the specimens can be stored and tested in an atmosphere with controlled humidity. Constant settings, as well as rising and falling ramps for temperature and humidity can be programmed quickly and easily using a display with "Touch" function.
The Model 618 is ideal for using fast ramps for temperatures or rel. humidity or for slowly increasing/decreasing over several hours. An additional air conditioner allows the operator to carry out low-temperature cycles down to - 40 ° C.
