MODEL 7951

A VARIABLE DILUTER

Dilute 1:10 | 1:31.6 | 1:100 | 1:316 | 1:1000

The VKL-mini is a diluter with two cascadeable, variable dilution modules. The system needs an external compressed air supply (8 bar max.). Due to the modular setup with the connector block and the dilution modules, a wide range of dilution ratios can be covered.
To install and operate the 7951 VKL-mini no additional tools are required. All connections are easy to lock or unlock. This enables an easy installation and fast change of dilution ratios. Due to the operating principle no sampling in under or over pressure conditions is possible. Aerosol in, aerosol out, and exhaust air out have to be operated under the same atmospheric pressure.
No power supply is needed.
