Size Test Meters
Measurements of pH,
ORP, Conductivity, TDS Total Dissolved Solids and Salt are fundamental
to water and liquid quality, and these pocket testers offer high reliability
and accuracy at a very affordabte price.
is measured by an electrochemical sensor that indicates the acidity or
alkalinity of the liquid. The instruments read this measurement and display
it on the screen. Temperature may affect the pH measurement, and most
of the listed testers automatically compensate for the temperature factor
(A TC). At pH 7.00 there is no effect of temperature and the default temperature
built in is 77 of or 25 °C. A Single Junction electrode is suitable
when water or liquid is relatively clean. Double Junction electrodes offer
extra protection for the sensors suitable for harsh, corrosive, dirty
or industrial liquids.
is a measurement of Oxidation Reduction Potential (mV) most commonly used
to measure the effectiveness of water disinfection systems using sanitizers
such as Chlorinate, Bromine, Ozone, Peroxyacetic Acid, Hydrogen Peroxide
etc. It is also commonly used in waste water treatment for oxidation of
cyanide waste, chrome reduction etc. ORP standards have been long established
for water sanitation, and are recommended over ppm measurements with traditional
is measured in micro siemens or micro mhos and is an indicator of the
number of ions present in solution and is a measurement of their build
up in water and liquid systems. Rinse water, DI water, cooling towers,
horticulture, wash water systems, swimming pools, aquaculture, drinking
water, food-process and facility waters-are common applications of conductivity.
Conductivity is very easily affected by temperature and all featured testers
automatically compensate for it.
is a measurement of total dissolved solids dissolved in water or liquids
and is read in ppm or mg/l. It is a conductivity measurement with a translation
to ppm by a conversion factor calibrated to natural water systems.
Salt is a measurement
of sodium chloride build up in water systems based on conductivity and
calibrated with a factor adjustment for salt concentrations. Commonly
used to measure salt concentration in aquaculture, swimming pools salt
generation systems and brine solution, or wherever salt is of interest
