Features of XL20
Dual channel measurement and display for fast and flexible research-grade analyses
  • Automatic temperature correction: ATC probe in each channel
  • Accepts two-cell and four-cell conductivity probes
  • Built-in replatinizing circuit
  • Provides inputs for two- or four-cell conductivity probe, pH/mV electrode, ATC probe, plus an input for the accuFet* nonglass electrode
  • Advanced circuitry and shielding prevent crosstalk and other interference
  • Password security to protect data from deletion
Versatile Conductivity Mode
  • Measure conductivity from 0 to 5 x 10cµS/cm, resistivity from 3ohms·cm to 100megohms·cm, salinity from 0 to 60ppt
  • Selectable temperature coefficients, cell constants and display units ensure accurate readings throughout a broad range of samples
  • Accepts simple two-cell probes or versatile four-cell probes for greater linearity over a wide range
  • Use k=1 cells for general purpose, 0.1 cells for high purity water, or 10 for brines or other concentrated solutions
Full-function pH and mV capabilities
  • Extended pH range: -2 to +20pH
  • Adjustable resolution to 0.001pH
  • Reads to 0.1mV for accurate titrations and ORP readings, too
  • Calibration at up to 6 points for exceptional accuracy of ±0.002pH
Extensive GLP capabilities
  • Customizable printer/computer output
  • 1000-reading datalog capability
  • Print Setup lets you print exactly what you want, when you want
  • Displays time in 12- or 24-hour format, date in U.S. or international format
  • USB port lets you connect keyboard, mouse, or trackball for meter control, or connect printer or PC for data output
  • RS-232 serial port lets you connect to PCs or printers without USB, or frees computer USB port while using the meter is in use
  • Ethernet allows unmatched LAN connectivity plus software upgrades
