Parameter pH, ORP, DO, Cond., Salt, TDS, Sea Gravity, Temp., Turb. ( LED), Depth, GPS Cat. No. U-52G ( 30M)

Measure and display pH, mV, conductivity, TDS, salinity, dissolved oxygen, turbidity, seawater specific gravity, water depth, and temperature simultaneously Auto-calibration feature simplifies calibration of pH, dissolved oxygen, conductivity, turbidity, and depth Built-in GPS— ideal for environmental surveys Rugged housing is both waterproof and shock resistant Stores up to 10, 000 readings with USB connectivity for export of data to a PC These handheld, waterproof meters feature a large 3-1/ 2" ( 8.9 cm) , easy-to-read LCD with backlighting for use in dark and low-light conditions. Multiple parameters can be measured and displayed at the same time. USB/ probe connectivity, GPS info, and battery power are also indicated via the display. Variable contrast allows you to adjust for extreme ambient light conditions. Meters are designed for one-handed operation. Probes are attached via a quick-connect connector allowing for fast setup. Unique auto-calibration feature provides hassle-free meter setup. Turbidity sensor offers better accuracy than most other conventional water quality meters. Polarographic DO sensor features improved stability, fast response, and easy maintenance. Auto-hold function freezes average data values providing more time to verify or transcribe data. Up to 10, 000 data sets can be stored and later transferred to a PC via a built-in USB connection. Units of measure are user selectable which helps you save time. What' s Included: one probe, one 500-mL bottle of pH 4.0 buffer solution, one 250-mL bottle of KCl solution, DO sensor installation set, cleaning brush, calibration cup, batteries, shoulder strap, and carrying case.
