User-replaceable sensors and cables and convenient Quick Cal feature makes it extremely user friendly. Mil-spec (military spec) connectors, IP-67 waterproof and rubber over molded case, and 1-meter drop tests ensure the instrument remains in your hands to provide years of sampling even in the harshest field conditions. The feature set of the Pro2030 results in a low total cost of ownership over the life of the product and proves that it is smarter, tougher, and more versatile.


Fast response times with the Polarographic or Galvanic DO sensor allows you to complete your sampling routine quickly. The long life of the Polarographic sensor saves time and money and reduces your overall cost. The Galvanic sensor enables you to start sampling immediately without a warm-up period. Either sensor you choose for the field will give you accurate, quality data.

The super-stable 4-electrode conductivity cell is built into the cable and will provide years of accurate data. The cells are designed for rugged field performance and are easily cleaned and require minimal maintenance.

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
