"We've used YSI handheld products - DO and pH meters - in the past and present and regardless of application they've always performed well."

The Pro Series product line was designed with our customers in mind and directly from customer feedback.  Versatility was a constant theme since everyone is trying to do more with less.  A lot of companies claim versatility but it's more than talk - it has to be central to the product line.

The Pro Series instruments were designed to go from one application to another quickly and easily.  Whether it's a wastewater lab or aeration basin, groundwater low flow study or lake profiling the Pro Series instruments are versatile enough to give you what you need.  Now doesn't that sound refreshing?

Versatile Features

• Choose the DO technology that's right for you - optical, polarographic or galvanic.
• One simple brass insert on the back of the instrument accomodates a belt clip, cable management kit, tripod, or ultra clamp.
• Pro Comm II communications saddle simply clamps onto the instrument to allow USB communications directly to the PC and Data Manager desktop software - download data or configure instruments or conduct real-time studies...
• Cables are designed to be used on more than one instrument.  For instance, the Pro Plus instrument can use any of the Pro Series line of cables.
• Sensors can be used on multiple cables.  For instance, the pH sensor is the same for the 1010, 1020, 1030, 10, or Quatro cables.
• The soft-sided carrying case has velcro strips on the outside of the case to allow you to attach a few cable management kits to change from one parameter option or cable length to another quickly and conveniently.
• Lab pH and ORP probes are available to go from a field to lab instrument with a simple, quarter turn connector cable change.
• Various flow cells are available allowing you to measure in a flow cell by attaching it to the cable.
• The Quatro cable allows you to use two ISEs, DO, conductivity and temperature at one time - or simply plug any of the ports to determine what parameters you want to measure.
• The ultra clamp, tripod or lab dock allow you to measure in any setting by allowing you to secure the instrument to the side of a boat, bench top, or if you just want to set it on the ground.
• Cable weights can easily be connected to the probe guard to provide assurance you are at the correct depth or to prevent the cable from blowing around if sampling off a bridge.
