VLM DosiCORR® ED Electronic Gas Dosing System for the Kesternich Test
Highly sensitive electronic mass flow meter
The electronic gas dosing system for the Kesternich test (DosiCORR® ED) 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 test chambers belonging to the VLM mid-range (CON, CON-SAL and CCT) featuring Jumo dTRON and Jumo Imago controller will be equipped with this option. This flexibility is possible due to the fact that the DosiCORR® ED gas dosing system operates independently from the process controller built into the basic test chamber.
The operation of DosiCORR® ED gas dosing unit is simple. At the beginning of the Condensation test the control button is pressed on the control display of the DosiCORR® ED gas dosing unit which releases the
predefined volume of SO2 into the test chamber.
Customer Benefits
- High flexibility in choosing the basic type of the test chamber – the DosiCORR® ED system operates in combination with (almost) all chamber types and all controllers
- User friendly operation
- Highly sensitive electronic mass flow meter allows accurate gas dosing
- Modular design of VLM test chambers allows easy adding of the DosiCORR® ED option long after the chamber has been commissioned
- The complete system is designed according to the highest safety standards; the DosiCORR® ED system with SO2 bottles is enclosed in a separate casket which is continuously ventilated
-
Safety
SO2 is a poisonous gas and for this reason was the safety of the operating personnel one of the main DosiCORR® ED design parameters. For this reason this system meets the highest safety standards. Some of the features are:
- The SO2 bottles are kept in a permanently ventilated casket inside the bench underneath the test cabinet
- The casket is made of a special, fire-resistant material specially designed for this purpose
-
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 volume of the gas per cycle (in litres) is controlled by the control unit with a handy digital display.
- The standard gas dosing volume for Kesternich test is 2 L per test cycle (one test cycle takes typically 24 h).
