Drinking Water pH Portable Meter

HI-99192 and FC2153 are ideal for on-site spot checks of drinking water.

The pH of potable water is fundamental to ensure safe water quality. If the pH is too low, drinking water will be corrosive to the distribution system and water pipes in homes. If it is too high, it can reduce the effectiveness of disinfectants. The pH of water also influences aesthetic or cosmetic properties including taste, odour, and clarity. Most public water operations maintain pH between 6.5 and 8.5.

Many factors affect pH measurements. An accurate temperature measurement and temperature compensated pH, along with at least two calibrated pH standards will improve the quality of the pH measurement. Often pH electrodes respond sluggishly in potable water samples due to the nature of the water, the sample temperature or the design of the electrode.

The HI-99192 together with the FC2153 pH electrode solves all the problems found with standard pH systems. This specialised electrode offers numerous features that improve pH testing in drinking water. The spherical pH bulb features a low resistance pH glass that responds quickly to the sample (even at cold temperatures). It also has a refillable single junction Ag/AgCl reference that is used with a KCl electrolyte and has three ceramic junctions to ensure continuity and provide quick and reproducible measurements (even in low ionic strength waters).

About the FC2153 electrode

FC2153 pH electrode has a built-in temperature sensor for temperature compensated pH and temperature readings and contains an integral pre-amplifier to provide stable measurements in electrically noisy environments. The glass-bodied probe has a Quick Connect DIN and 1m cable.
