Transcript of 21st Century Water Testing
A Comparative Look at Testing Equipment for the Water Quality Industry
Christian KrzykwaTechnical Product Manager
*pH is the a measure of acid (H+) and base (OH-) compounds in water*pH ranged from 1-14
and pure water has a pH of 7*It can be measured by
a number of different methodologies
*Testing for these three components of the nitrogen cycle are key in healthy marine aquariums*Ammonia and Nitrite
are toxic at high concentrations
*Phosphate plays an important role in the health of reef aquariums*No phosphate
inhibits coral growth while too much promotes algae
*There are hundreds of ways to detect trace chemicals in water*Electrochemistry*Spectrophotometry*Spectroscopy*Chromatography*Refractometry*Polarimetry *Microscopy
*The simplest form of testing uses similar chemistry to digital photometer testing*Requires user to
estimate based on color development
*Test can come with powder or liquid reagents*Some manufacturers
simplify the process with reagent strips
*Small and inexpensive*Takes liquid and
powder reagents*Not very versatile,
each meter test one parameter
*Expensive and immobile*Often give the most
accurate results*Models with
wavelength selection are most versatile*Require powder and
liquid reagents
*More versatile, capable of running multiple test parameters*ITS patented
reagent strip delivery system with photometer is fastest method
* Save, Send, Share data
* Add notes* Export via CSV/Excel* Customize and only
download the tests you need
* Flexible to the user/application
*Smartphones equipped with Bluetooth SMART 4.0 and later can manage data wirelessly*eXact meters are
smart phone compatible for data management
