Nutrient Analyzer
The Smartchem 170 can analyze nitrate, ammonia, ortho-phosphate, Kjeldahl nitrogen and phosphate and silicate in water and soil samples.
![Spectrophotometer](../../images/spectrophoto-meter-phytoplankton-absorbtion-light-visible-ultravioletjpg.jpg)
Cary 300 Spec
This instrument measures the light absorbed, transmitted, or reflected by the sample at each wavelength in the UV and Visible spectrum.
