Introduction
The ME-6937 Aquatic Productivity Bottles rest in a rack
that provides consistent and reliable light control for
quantitative aquatic productivity studies. Students fill
the bottles with algae solution or pond water and then
measure the dissolved oxygen concentration in the solu-
tions before and after incubation in fluorescent light. By
comparing the dissolved oxygen concentrations in each
solution, students learn about the relationship between
light intensity, dissolved oxygen concentration, photo-
synthetic activity, and the primary productivity of
aquatic ecosystems.
• The identical transparent bottles nest in each of
five rack positions.
• The custom design of the rack shields the bottles
from light by blocking a fixed percentage of light
in 25% increments from zero to 100%.
The PASPORT Water Quality Sensor measures tempera-
ture, pH, dissolved oxygen, and conductivity. It also
supports Ion Selective Electrodes (ISE) and the Oxygen
Reduction Potential Electrode (ORP). It is designed for
a wide range of water studies.
The PASPORT Dissolved Oxygen Sensor and Water
Quality Sensor work with a PASPORT interface such as
the ones listed below.
