In selecting water quality equipment it is critical to take into account the type of application, be it industrial process lines, hand held meters or bench top models. Examples ranges from test strips, pocket testers, single parameter meters, multi parameter meters and bench top meters.

3. Did you ever think about buying a water quality equipment?
If you ever had a hard time deciding what type to choose,

4. In selecting water quality equipment it is critical to take into account
the type of application, be it industrial process lines, hand held meters
or bench top models. Examples ranges from test strips, pocket testers,
single parameter meters, multi parameter meters and bench top
meters.

5. Here are the types of water quality measurement instruments and
their applications or what type of parameter/s are being measured.

6. For typical probe type water quality testing instruments:
pH, conductivity, Resistivity, Salinity, TDS, Chloride, Dissolved Oxygen,
Temperature, and ORP or Redox.

7. Photometer type instruments measures:
Alkalinity (total), Alkaphot M, Alkaphot P, aluminum, ammonia, boron,
bromine, calcium hardness, chloride, chlorine DPD 1, chlorine DPD 2,
chlorine DPD 1 and 3, chlorine DPD 4, chlorine HR, chlorine dioxide
DPD, chlorine dioxide LR, chlorine dioxide HR, chromium VI hexavalent,
copper (coppercol), copper free, color (includes turbidity), cynuric acid,
fluoride, hardness (hardicol), hydrazine, hydrogen peroxide LR,
hydrogen peroxide HR, iron LR, iron MR, Iron HR, magnesium
(magnecol), manganese, molybdate LR, molybdate HR, nickel, nitrate,
nitrite N, nitrite (NaNO2), organophosphate, ozone, pH phenol red,
phenol, phosphate LR, phosphate HR, potassium, silica, silica HR
sulphate, sulphide, sulphite, and zinc.

8. Hand held meters are usually used to measure TDS (total dissolved
solids) in the water supply of home or office or anywhere water quality
is needed to be at a safe level. It is ideal for all water purification
applications, including waste water regulation, aquaculture,
hydroponics and more.

9. It also provides direct reading of total chlorine in less than two
minutes. It has low detection limit up to 0.01 parts per million. The
measurement is unaffected by sample color or turbidity. It can store
memory, tags and recalls up to 15 readings. These instruments must be
approved by EPA and is an acceptable method of wastewater
compliance monitoring of total chlorine.

10. These testers must accurately measure the TDS level in the water.
These meters are ideal for testing reverse osmosis membrane
performance and determining the need for replacement. Ideal for all
water purification applications, wastewater regulation, aquaculture and
colloidal silver.

11. They are also highly efficient and accurate because it contains
advanced microprocessor technology. Some have automatic functions.
After operating for three minutes in the same condition, the
measurement simply stops. This type of meter will also turn off after 10
minutes of non-use to conserve battery power.

12. There are also school kits that allows water learning program designed
to help teach students about water and its importance to life. The ease
and accuracy of these water test kits prompts parents, student and
educators to explore water quality in science classes and school fairs.
They are ideally sized for a science fair project or small group
experiment.

13. Water knowledge booklets and test strips engage students in
identifying 8 water contaminants or conditions, and teaches
appropriate corrective action to improve water quality. This kit also
helps the students learn about water wells, the hydrologic cycle and
how water is acquired and naturally removes some contaminants. The
types of tests include alkalinity, chlorine, copper, hardness, iron,
nitrates, nitrites, and pH.
