Pocket-Size pH and Conductivity Meters

pH meters measure acidity/alkalinity. These units are
accurate enough for testing the pH of fountain solution of printing presses, yet
inexpensive enough to use at work or home for testing soil, water, food service
compliance with HACCP regulations,
tropical fish aquariums, aqua culture, hydroponic gardening
and farming, winery/brewery process control, and swimming pools.
They are even used by sushi restaurants to make sure the
rice meets health department guidelines!
HINTS: To test the pH of soil in gardens and lawns, mix two parts of distilled or
de-ionized water per part of soil, let the solids settle to the bottom, and measure the pH of
the solution at the top. To test rice, add enough
distilled or de-ionized water to make the rice moist enough to measure.
When checking cooked food, allow it to cool to room temperature, so the pH
bulb will last longer. In such instances, a temperature compensating
meter, such as the HI98127 or HI98128 will give more accurate readings.
Conductivity meters measure either electrical
conductivity (EC) as expressed in "micro-siemens" or total dissolved solids
(TDS) expressed in parts per million (ppm), so you can determine solution
strength without regard to "buffers" and other chemical agents added to maintain
pH. Conductivity is important for water
conditioning and treatment, environmental, and electro-plating applications.
In hydroponic gardens and farming, greenhouses and aqua culture, measurement assures the
proper level of fertilizer is being dosed.
All units are rugged, pocket-size, battery operated (batteries are included), and have LCD
displays. They measure directly with no need to remove messy samples.
