Replacing the popular YSI 85 SCOOT the Pro 2030 is a handheld meter designed specifically for measuring temperature, dissolved oxygen, conductivity, salinity and barometric pressure.

The Pro 2030 is a rugged field meter with Mil-spec (military spec) connectors, IP-67 waterproof and rubber over molded case. The 1-meter drop test specification ensures that the instrument remains in your hands to provide years of sampling even in the harshest field conditions.

All sensors have been tested and certified to the Environment Agencies MCERTS scheme to offer the best confidence in your collect field data.

Additional features include:

  • Internal barometer for highest accuracy
  • Choose field DO sensors (Polarographic or Galvanic)
  • Quick Cal allows DO calibrations within seconds with the push of a button
  • Stores 50 data sets
  • Graphic, backlit display and glow in the dark keypad
  • Available with 1, 4, 10, 20, or 30-meter cables (4-meter and longer cables include cable management kit)
  • View display with polarized sunglasses on
  • Fastest DO response time on the market with 95% response in 8 seconds with standard membrane
  • Multiple languages include English, Spanish, French and German
  • User replaceable DO sensors and cables
  • Conductivity cell built-in
  • 3-year instrument; 2-year cable warranty

When ordering the Pro2030 you must order the instrument, cable, and DO sensor separately, allowing you to choose the system that best fits your application. Conductivity is part of the cable you order and included in the cable purchase.
