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.
