The YSI Professional Plus is not a refinement. It came straight out of the imagination of our customers... and the ingenuity of a multi-disciplined team dedicated to making the ideal solution come to life. Our focus never wavered because listening to our customers is a continuous process, and the heart and soul of our commitment.
Designed to be tough and smart in the lab or field. And extremely versatile. The Pro Plus accommodates any combination of YSI Pro Series cables, sensors, and accessories. Want to measure DO in the field? Maybe pH/DO/Nitrate? Or perhaps you need it to be a lab instrument that measures BODs? Whatever you need...the Pro Plus is your choice.
Do your job with confidence even in the harshest field conditions. The drop-tested Pro Plus was designed tough with military-spec connectors, a two-year warranty on all cables, weighted sensor guards, and a rubber over-molded case with three- year warranty. Its interchangeable sensors and extra-durable cables nearly eliminate down time. And its low overall cost of ownership means you’re making a worthwhile investment for years to come.
Quatro Cable
The multiparameter Quatro cable allows the measurement of temperature, conductivity, salinity, dissolved oxygen and any two ISEs -pH, ORP, ammonium, nitrate or chloride.
What a Come-back
A YSI customer accidentally dropped his Pro Plus off a 40-foot bridge into the river below. A week later, he and his team came back. Using a long pole to scrape the river bottom, they found the cable and then the meter. They were amazed to find that — after a week submerged in a muddy river bed — their Pro Plus still worked.
Not All is Lost
A YSI wastewater customer knocked a Pro Plus into an aeration basin. Seemingly lost for good, he reluctantly moved on. One year later, the tank was drained to complete minor maintenance. And there lay the meter. After a bit of cleaning, they turned it on. Not only did it work, but it’s still being used today.
Smarter....
The technology-smart YSI Pro Plus has all the built-in support you’ll need for the lab or field. It provides multiple languages, detailed GLP data, on-screen Help to eliminate the need for a bulky manual, sensor diagnostics, up to six-point auto-buffer recognition, re-cal prompts, user-defined auto-stable function, and security passwords for extra protection. And much more.
Most Versatile....
Connect any Professional Series cable (excludes ODO cables) and probe option to the instrument and use the convenient cable management kit to keep everything simple and organized. Cable options range from 1-, 4-, 10-, 20-, and 30-meter choices (up to 100-meters on DO only cables). Use lab or field probes and switch between the two quickly. The Pro Plus makes an ideal lab BOD instrument with the proven self-stirring BOD probe (EPA Approved). A convenient handstrap can be used on either side of the instrument. A complete family of accessories also increases the versatility of the Pro Plus. Choose among accessories including carrying cases, flow cells, cable weight, belt clip, tripod, and c-clamp.
