American Marine Pinpoint Nitrate Monitor

High nitrate levels stress aquarium residents and fuel algae growth, especially in sensitive reef tanks. The Pinpoint Nitrate Monitor is a precision spot monitor that makes it easy to quickly and accurately tests these levels. Nitrate levels can be measured within 1 part per million (ppm) after calibration in either the low range (1 to 10 ppm) or high range (10 to 100 ppm) settings. The meter, probe, and calibration fluid are included. Designed for saltwater use only. _____________________________________________________________________________________
