VPP-01 Density Meter Secondary Converter

Compact secondary converter for radioisotope density meters with touchscreen control, calibration tools, and a 4-20 mA current output.

VPP-01 secondary density meter converter

VPP-01 is designed to convert the signal from scintillation detector-based density meters into a normalized signal corresponding to process density or concentration.

The unit is developed by BSL-LAB for industrial teams that need a serviceable local device with a clear interface, flexible calibration logic, and stable operation in production environments.

Application areas:

  • chemical production
  • oil refining and oilfield service
