Accessories

  • Automated Vapor Pressure in Gasoline, Aviation Fuel, Crude Oil or LPG. The analyzer is supplied mounted inside a stainless steel cabinet, pre-configured for connection to the Ex-proof external purge, and prepared for up to 4 measurement streams.
  • Calibration software ERASOFT RCS – Windows software for PC installation is included. Temperature and pressure sensors are easily calibrated without disassembling the measuring cell.
  • Full color touch screen
  • Includes variable vapor/liquid ratio program from 0.02/1 to 100/1, full multipoint or single point curve measurements.
  • Sample introduction: Automatic via internal piston – No external vacuum pump required.
  • Up to 4 inputs (3 samples + control) for programmable sequential measurement, as required.
  • Customized reports for each trial.
  • Allows crude steam pressure measurement (with optional specific software and agitation built into the cell)
  • Automatic cleaning system.
  • Quality control: The software includes quality control measurements according to ASTM D6299, with up to 8 control samples in parallel, with programmable alert levels between 1 and 3 times the standard deviation.
  • Patented maintenance-free automatic piston lubrication system.
  • Integrated PC with Ethernet, RS422 and RS232 (fieldbus / modbus) interfaces
  • I/O system with 4 analog outputs (4-20 mA), 4 digital outputs and 4 digital inputs. These inputs and outputs are fully configurable with the Analyzer control software.
  • Large database of results.
