The new Quatro cable attached to the Pro Plus allows you to utilize 4-ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate creating an extremely powerful handheld multiparameter instrument. 

Toughest
The Pro Plus instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on. Other tough features include a 3-year warranty, Mil-spec connectors, rubber overmolded case, and a 2-year cable warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure  expected field-durability.

Smartest
The instrument provides numerous benefits from the following features; 2,000 data-set memory, password protection, backlit display and keypad, graphic display with detailed Help functionality, re-cal prompts, user defined fields, detailed GLP, auto stable, Hold All Readings function,

Data Manager software for the desktop, USB connection, auto-buffer recognition, and flexible folders and site lists for logging data.

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. 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.

Free - Data Manager
Data management can become a daunting task over time but with the Data Manager software this task is much simpler and efficient. Download data, configure instruments, and conduct real-time studies easily with Data Manager software. View data graphically or in tabular form and export data as needed to other programs. Data Manager software is a very powerful tool. So powerful in fact, that we give it to you at no charge when purchasing a Pro Plus. After all, it's all about the data!

When purchasing the Pro Plus you will receive the instrument, manual, batteries, communications saddle, USB cable, and Data Manager software. Cables and probes are ordered separately.
