The rugged, easy-to-use portable dissolved oxygen (DO) meters can be quickly calibrated with a push of a button for fast, accurate measurements and response times. The glow-in-the-dark keypad allows for easy navigation in low-light areas, while the display is viewable in all lighting conditions, even direct sunlight while wearing polarized sunglasses.
The meters are available with either a classic polarographic or “instant-on” galvanic user-replaceable DO probe with screw-on membrane caps for ease of maintenance. The cap membrane is prestretched at the factory making it easier to install. The membrane material requires less stirring and offers faster response time.
The rubber over-molded case provides a sturdy hand grip and protects meters while in the field. Meters have a IP67 waterproof rating even without the battery lid. Additional features include adjustable right- and left-handed strap, battery-life indicator, and multiple language display (English, Spanish, French, and German).
