pNa tester for the efficiency of the resins in the softening plants
HI 98202 (PNA) is a tool pocket and economic for the control of plant water softening.
fact with pNa is possible to determine the efficiency of ion exchange resins used in this type of installations by means of the measurement of ion concentration sodium (Na + ) upstream and downstream of the plant. Consequently, the operator can determine with certainty and precision the moment when it is necessary to replace the exhausted resin. To measure the concentration of sodium ions using a pNa sensitive glass electrode.
When you know the concentrations of specific chemical substances in a solution containing sodium (eg caustic soda or hypochlorite), it is also possible to relate the readings of PNA with concentrations of other specific substances in the solution.
pNa is robust and ergonomic design, suitable for field measurements. It is powered by standard batteries and is calibrated manually to ensure the accuracy of the measurements.
