*Most thermometers use electrical resistance to detect temperature change

*In marine aquaria refractometry is the most practical method of detecting high salt levels

*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

*Total Hardness measures measures cations like Ca2+ and Mg2+*Carbonate Hardness

measures anions

*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
