# 140 Dissolved Phosphate in Water
Colorimetric test strips. (1 test per strip)
Testing for Dissolved Phosphate in water is common, but
usually found in low concentrations. Because of low
concentrations, phosphate is involved with regulating bilogical growth and productivity in natural waters.
The color chart for this test allows you to read Dissolved
Phosphate in micrograms/L or ppb.
The Color Comparator Chart for this test allows you to read Phosphate levels in water at:
~0, 200, 400, 600, 1000, 2500 microgms/L or ppb.
(Note: concentration units are micrograms per Liter or parts per billion).
