The ranges work to test water quality in wastewater, surface water, ground water, or drinking water. A clear LCD display shows results in ppm or mg/L with enunciators to aid in use and troubleshooting.

No meter warm-up or polarization required so you can take dissolved oxygen measurements right away.

Perfect for conditions that ruin ordinary dissolved oxygen meters! This completely waterproof meter reads dissolved oxygen in mg/L, ppm or % saturation. Its waterproof construction lets you thoroughly wash the meter to maintain working condition.
