The ProQuatro was designed with the 4-port Quatro cable in mind. Combine 4 sensors on a single cable for comprehensive multiparameter sampling to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate. Pairing the ProQuatro with the 4-port cable creates an extremely powerful handheld multiparameter water quality instrument.
Toughest
The ProQuatro meter meets the demands of true field work. Made from ultra-rugged components to withstand harsh field conditions, 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 over-molded case, scratch-resistant lens, and a 2-year cable warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.

Most Versatile
ProQuatro is easily customized to be the ideal choice for low-cost water quality sampling. Connect the ProQuatro handheld to any Professional Series cable and probe option for parameter options including dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids, pH, ORP, ammonium, nitrate, chloride, and temperature.
Cable options range from 1-, 4-, 10-, 20-, and 30-meter choices (up to 100-meters on DO only cables) and the convenient cable management kit to keep everything simple and organized. Use lab or field probes and switch between the two quickly. The ProQuatro 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 increase the versatility of the ProQuatro and help get the job done right. Choose among accessories including carrying cases, flow cells, cable weights, belt clip, tripod, and c-clamp.
Added Versatility Features Include:
- Multiple parameter options and cable lengths
- Multiple user-replaceable sensor options and a choice of DO sensors*
- Lab-grade ISE sensors and BOD probe available to make a true lab/field instrument
- Adjustable right- or left-handed hand strap*
- Languages – English, Spanish, German, French, Italian, Norwegian, Portuguese, Japanese, Chinese (Simplified and Traditional)
- Wide array of accessories are available from flow cells, to shoulder straps, to carrying cases
