1. Portable pH-meters.
¹1 given portable pH-meters. pH - is one of the most important
indicators of water quality is largely determined by the
nature and rate of chemical and biological processes, it
reflects the degree of acidity or alkalinity of water. At
neutral pH acid and alkali present in the water in equal
amounts (or nonexistent). Such an environment is the most
balanced and optimal for the passage of biochemical reactions
in the body. Water with a low pH (ie acidic) has increased
corrosivity, and with a high pH (ie alkaline) - has a characteristic
suds to cause eye and skin irritation. Increasing pH is
usually increase hardness and scale is out of order washing
machines, boilers, etc.
2. Portable ORP-meters.
¹2 given portable ORP meter. ORP (redox potential, rH, ORP)
- a measure of the reactivity of the elements and their
compounds in the reversible chemical processes associated
with the change in the charge of the ions in solution (by
transmission electron or accession). ORP value for each
redox reaction can be both positive and negative. In humans,
the energy released during the oxidation-reduction reactions,
is spent on the maintenance of homeostasis and regeneration
of body cells. The water absorbed optimally when it is close
to the ORP of internal environment. In the vast majority
of cases ORP of drinking water is more important. In this
case, the water in the tissue takes up electrons from the
cell body, and accordingly is subjected to oxidative degradation.
3. Portable conductometer and TDS-meters.
¹3 given portable conductivity and TDS-meters (Salimeters).
Control of salinity in the water as necessary to determine
the actual water quality (this is especially important for
water from the pump room) and to control the quality of
filtration systems, ranging from the pitcher filters and
ending with a reverse osmosis system.
4. Portable oximeters.
¹4 given portable oximeters. Oxygen is essential to most
living creatures on Earth for the process of synthesis of
energy in the body. Decreased oxygen saturation (for example,
in the winter when the water surface is covered with ice,
and aquariums - with insufficient aeration) adversely affects
the health and behavior of fish. Reduced oxygen concentrations
may also indicate that the water flow is actively putrefaction.
5. Portable clorinemeters.
¹5 given portable hlorine-meters. In cities with centralized
water supply, water chlorination - is the main method of
disinfecting. Therefore, control of the chlorine content
in water is particularly relevant in the case of the use
of water directly from the tap or use in aquariums of tap
water, which does not pass the boiling, sedimentation or
purification through a carbon filter. Control of the concentration
of chlorine is also required in swimming pools.
6. Complex water analyzers.
¹6 given portable integrated water analyzers - devices that
can measure several parameters of water.
