VLM DosiCORR® MD Manual Gas Dosing System for the Kesternich Test

Cost effective way of conducting the Kesternich test

Manual gas dosing system for the Kesternich test (DosiCORR® MD) in SO2 environment can be fitted to virtually any VLM test chamber (except for the SAL range) and regardless of the controller used. However for the cost-effective reasons only the smaller test chambers belonging to the VLM low-range (CON, CON-SAL and CCT) featuring JUMO dTRON and Jumo Imago controller are normally equipped with this option. This flexibility is possible due to the fact that the DosiCORR® MD system operates completely independent from the process controller built into the test chamber.

The operation of the DosiCORR® MD gas dosing unit is quite simple. At the beginning of the Condensation test the specified volume of SO2 is injected from the bottle into the lower part of the glass cylinder. Under the weight of the Paraffin oil in the upper part of the cylinder, the gas is displaced into
the test chamber.

Customer Benefits

  • Cost effective way of conducting the Kesternich test
  • High flexibility in choosing the basic type of the test chamber – the DosiCORR® MD system operates in combination with (almost) all chamber types and all process controllers
  • User friendly operation
  • Modular design of VLM test chambers allows easy adding of the DOSICORR® MD option long after the chamber has been commissioned

Safety

SO2 is a poisonous gas and for this reason, is the safety of the operating personnel of upmost
importance. It is for this reason recommended that:

  • Tests are conducted in a good ventilated room
  • The bottles with SO2 should be kept in closed containers made of special, fire-resistant material specially designed for this purpose (VLM can provide this item)

Applicable Test Standards

EN ISO 6988
DIN 50018
ASTM G 85

Process Control

  • The standard Kesternich test consists of two phases within one day cycle from which
    one features the introduction of the gas (SO2).
  • The standard gas dosing volume for the Kesternich test is 2 L per test cycle (one test
    cycle lasts typically 24 h).
