The Pro20 provides everything you need in a handheld dissolved oxygen meter. Ruggedness, simplicity and reliability are the cornerstones of the instrument’s design.

The YSI Pro20 dissolved oxygen meter is a rugged, user-friendly
instrument for DO measurement. The Pro20 can be used in
the lab or the field and can go from one to the other in seconds.

User-replaceable sensors and cables and convenient One Touch 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 Pro20 results in a low total cost of ownership over the life of the
product.

Fast response times with the Polarographic or Galvanic dissolved
oxygen sensors allow 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.

Additional features include:

• Internal barometer for highest accuracy
• Choose field DO sensors (Polarographic or Galvanic) or lab BOD probe for BOD in wastewater
• One Touch Cal calibrates within 3 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, 30 or 100-meter cables

Lab or field, the Pro20 is ready for whatever you need when it comes to oxygen meters.

When ordering the YSI Pro20 you must order the instrument, cable, and
dissolved oxygen probe separately, allowing you to choose the system
that best fits your application.
