Hanna Instruments pNa Meter (HI 98202)

• Measures sodium concentration in liquids.
• Accurately determines water hardness/softness
• Quick and inexpensive
• Simple-to-operate

The pNa is an easy-to-use and inexpensive instrument that can measure the sodium concentration in liquids. Especially useful for measuring the sodium concentration in soil extract solutions to determine salinity levels.

Was originally developed to test the hardness level of water:-

From the manufacturer "Water hardness is due to the presenceof magnesium and calcium ions. These make washing difficult, waste soap andcreate unpleasant scum and scale. With a zeolite system, the calciumand magnesium ions are substituted on a one-to-one basis with sodiumions from a resin. Once all the sodium ions are exhausted, the resinhas to be regenerated. This is currently determined by estimating thevolume of water that goes through the softener and guessing when tochange the resin! Even though this may work in some cases, it fails inmost since the sodium content of feed water is never constant. As aresult, either the resin is regenerated too early, waste of resources,or too late, causing damage due to scaling. With the pNa, you canmeasure the sodium content of feed water and exit water in seconds.When the resin is exhausted of sodium, there will be no exchange andthe pNa will read the same value at the two ends. Only then should theresin be changed. pNa takes guess work out of resin regeneration!"

HI 98202 (pNa) is supplied complete with protective cap, calibration screwdriver, batteries and instructions.
