YSI Professional Plus Multiparameter Water Quality Meter
PFAS Accepted Equipment
The YSI Professional Plus handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, and temperature. Also a very powerful lab instrument for BODs, pH, and ORP.
Additional probes are available on request, which measure the following parameters: pH/ORP combination, ammonium (ammonia), nitrate, and chloride.
The Pro Plus instrument meets the demands of true fieldwork. The instrument is rated to IP-67 standards even without the battery cover on. Other tough features include Mil-spec connectors and a rubber over-molded case. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field durability.
The instrument provides numerous benefits from the following features; 5,000 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.
Features:
Easy-to-install cable weights; can be daisy-chained for additional weight
Rubber over-molded IP-67 waterproof case
Rugged cables sensors and military-spec connectors
Scratch-resistant lens; viewable with polarized glasses
5000 data set memory
Detailed on-screen Help function
Interval or single-event logging
100 folder & site list data structure
